Answer:

C, E

Explanation:

Basic Concept: This question tests database auditing and query visibility. DP-300 expects you to distinguish between collecting audit events, retaining logs, and analyzing query behavior.

Why C and E is Correct: an Azure Policy initiative is correct because it is the feature whose normal purpose matches the stated requirement. an Azure Policy initiative can participate in administration workflows, but automation questions require the mechanism that can execute repeatable tasks with the correct scope and schedule. The scenario wording points to that specific behavior: You need to ensure that all the databases have the same configuration. an Azure Policy definition is correct because it is the feature whose normal purpose matches the stated requirement. an Azure Policy definition can participate in administration workflows, but automation questions require the mechanism that can execute repeatable tasks with the correct scope and schedule. The scenario wording points to that specific behavior: You need to ensure that all the databases have the same configuration.

Why A is Wrong: an Azure Policy assignment can participate in administration workflows, but automation questions require the mechanism that can execute repeatable tasks with the correct scope and schedule. It does not provide the required repeatable execution, scheduling, or deployment automation requirement, so it would not complete the administrative workflow reliably.

Why B is Wrong: Azure Automation runbooks execute PowerShell or Python tasks on a schedule, making them useful for Azure SQL maintenance workflows. It belongs to a different step of operations; this question needs the mechanism that can run or deploy the task repeatedly.

Why D is Wrong: Azure Automation runbooks execute PowerShell or Python tasks on a schedule, making them useful for Azure SQL maintenance workflows. It does not provide the required repeatable execution, scheduling, or deployment automation requirement, so it would not complete the administrative workflow reliably.

Task 1

In an Azure SQL database named db1, you need to enable page compression on the PK_SalesOrderHeader_SalesOrderlD clustered index of the SalesLT.SalesOrderHeader table.

Options:

Buy Now

Answer:

See the explanation part for the complete Solution.

Explanation:

To enable page compression on the PK_SalesOrderHeader_SalesOrderlD clustered index of the SalesLT.SalesOrderHeader table in db1, you can use the following Transact-SQL script:

-- Connect to the Azure SQL database named db1

USE db1;

-- Enable page compression on the clustered index

ALTER INDEX PK_SalesOrderHeader_SalesOrderlD ON SalesLT.SalesOrderHeader

REBUILD WITH (DATA_COMPRESSION = PAGE);

This script will rebuild the clustered index with page compression, which can reduce the storage space and improve the query performance

The script solution consists of three parts:

The first part is USE db1; GO. This part connects to the Azure SQL database named db1, where the SalesLT.SalesOrderHeader table is located. The GO command separates the batches of Transact-SQL statements and sends them to the server.

The second part is ALTER INDEX PK_SalesOrderHeader_SalesOrderlD ON SalesLT.SalesOrderHeader REBUILD WITH (DATA_COMPRESSION = PAGE); GO. This part enables page compression on the clustered index named PK_SalesOrderHeader_SalesOrderlD, which is defined on the SalesLT.SalesOrderHeader table. The ALTER INDEX statement modifies the properties of an existing index. The REBUILD option rebuilds the index from scratch, which is required to change the compression setting. The DATA_COMPRESSION = PAGE option specifies that page compression is applied to the index, which means that both row and prefix compression are used. Page compression can reduce the storage space and improve the query performance by compressing the data at the page level. The GO command ends the batch of statements.

The third part is optional, but it can be useful to verify the compression status of the index. It is SELECT name, index_id, data_compression_desc FROM sys.indexes WHERE object_id = OBJECT_ID( ' SalesLT.SalesOrderHeader ' );. This part queries the sys.indexes catalog view, which contains information about the indexes in the database. The SELECT statement returns the name, index_id, and data_compression_desc columns for the indexes that belong to the SalesLT.SalesOrderHeader table. The OBJECT_ID function returns the object identification number for the table name. The data_compression_desc column shows the compression type of the index, which should be PAGE for the clustered index after the script is executed.

These are the steps of the script solution for enabling page compression on the clustered index of the SalesLT.SalesOrderHeader table in db1.

Questions 11

Task 1

You need to implement a disaster recovery solution by using active geo replication for an Azure Azure SQL database named db1. The replica must be in the East US or East US 2 Azure region on a server named sql60152867-dr.database.windows.net. You may need to use SQL Server Management Studio and the Azure portal.

Options:

Buy Now

Answer:

See the explanation part for the complete Solution.

Explanation:

Requirement: Configure active geo-replication for Azure SQL Database db1. The geo-replica must be created in East US or East US 2 on the logical Azure SQL server:

sql60152867-dr.database.windows.net

The important point: in Azure SQL, the logical server name used in portal/T-SQL is usually:

sql60152867-dr

not the full FQDN.

Microsoft states that active geo-replication is configured per database, and a geo-secondary is created for an existing Azure SQL Database. After creation and seeding, changes from the primary are replicated asynchronously to the secondary.

Method 1 — Azure Portal Method

This is the safest method for the simulation if the portal is available.

Step 1: Open the primary database

Search for SQL databases.

Select the database named db1.

Confirm you are looking at the primary database, not an existing secondary.

Step 2: Open the Replicas blade

In the left menu of the db1 database page, scroll to Data management.

Select Replicas.

Select Create replica.

Microsoft’s portal workflow is: open the database, go to Data management > Replicas, and choose Create replica.

Step 3: Configure the geo-secondary replica

On the Create SQL Database replica page, configure the target like this:

Setting

Value

Database

db1

Replica type

Geo replica / Active geo-replication

Target server

sql60152867-dr

Region

East US or East US 2

Database name

db1

Compute + storage

Keep same or compatible with primary

Elastic pool

Only choose this if the lab specifically requires an elastic pool

Do not create a failover group unless the task asks for one. This task says active geo replication, so configure a database-level geo-replica, not a failover group. Microsoft explicitly separates active geo-replication from failover groups and notes that active geo-replication is configured per database.

Step 4: Review and create

Select Review + create.

Confirm the target server is:

sql60152867-dr

Confirm the region is either:

East US

East US 2

Select Create.

Azure will create the secondary database and begin the seeding process. Microsoft notes that the secondary database has the same name as the primary by default and begins replication after it is created and seeded.

Step 5: Verify replication

After deployment completes:

Go back to the primary database db1.

Open Replicas again.

Under Geo replicas, confirm that a replica exists on:

sql60152867-dr.database.windows.net

Confirm the replica status is healthy, online, or synchronizing.

You can also open the target SQL server sql60152867-dr and verify that a database named db1 now exists there.

Method 2 — SSMS / T-SQL Method

Use this method if the portal is awkward or the exam simulation expects T-SQL.

Step 1: Allow SSMS connectivity

Before connecting with SSMS:

In Azure portal, open the primary SQL server hosting db1.

Go to Networking or Firewalls and virtual networks.

Add your client IP address.

Repeat this on the secondary server:

sql60152867-dr.database.windows.net

This matters because SSMS must be able to connect to the Azure SQL logical server.

Step 2: Connect to the primary server in SSMS

Open SQL Server Management Studio.

Connect to the primary Azure SQL logical server that hosts db1.

Use SQL admin credentials or Microsoft Entra admin credentials.

In Connection Properties, connect to the database:

master

This is important. For Azure SQL Database geo-replication setup through T-SQL, run the command from the master database on the primary server.

Step 3: Run the active geo-replication command

Run this query:

ALTER DATABASE [db1]

ADD SECONDARY ON SERVER [sql60152867-dr]

WITH (ALLOW_CONNECTIONS = ALL);

Microsoft documents that ALTER DATABASE ... ADD SECONDARY ON SERVER creates a secondary database for an existing Azure SQL Database and starts data replication. The official example also uses WITH (ALLOW_CONNECTIONS = ALL) to create a readable geo-secondary.

Step 4: Verify the replication link

Still connected to the primary server, run:

SELECT *

FROM sys.geo_replication_links;

Or use:

SELECT *

FROM sys.dm_geo_replication_link_status;

Microsoft lists sys.geo_replication_links and sys.dm_geo_replication_link_status as views used to return information about existing replication links and replication status.

Optional PowerShell Method

Only use this if the lab gives you Cloud Shell or PowerShell access.

New-AzSqlDatabaseSecondary `

-ResourceGroupName " < PrimaryResourceGroupName > " `

-ServerName " < PrimaryServerName > " `

-DatabaseName " db1 " `

-PartnerResourceGroupName " < SecondaryResourceGroupName > " `

-PartnerServerName " sql60152867-dr " `

-PartnerDatabaseName " db1 "

Microsoft identifies New-AzSqlDatabaseSecondary as the PowerShell cmdlet that creates a secondary database for an existing Azure SQL Database and starts replication.

Final Answer / What You Must Achieve

The task is complete when:

Database db1 still exists on the primary server.

A secondary database named db1 exists on:

sql60152867-dr.database.windows.net

The target server is in East US or East US 2.

The replica appears under db1 > Replicas > Geo replicas.

Replication status is healthy, online, seeding, or synchronizing.

You did not configure a failover group unless separately requested.

D, E

Explanation:

Azure RBAC is used to manage who can create, update, or delete the Synapse workspace and its SQL pools, Apache Spark pools, and Integration runtimes.

[Reference:, https://docs.microsoft.com/en-us/azure/synapse-analytics/security/synapse-workspace-synapse-rbac, , https://docs.microsoft.com/en-us/security/benchmark/azure/baselines/synapse-analytics-security-baseline, , , , , , , Basic Concept: This question tests Azure monitoring and performance management, including which metric, log destination, or alerting behavior fits the operational requirement., Why D and E is Correct: a custom role-based access control (RBAC) role is a security-related control, but its value depends on whether the requirement is identity, encryption, auditing, network isolation, or data exposure reduction. This fits the case because the requested outcome is: You need to ensure that users from each company can view only the data of their respective company. The selected feature addresses that outcome directly rather than relying on a workaround. a security policy is correct because it is the feature whose normal purpose matches the stated requirement. a security policy is a security-related control, but its value depends on whether the requirement is identity, encryption, auditing, network isolation, or data exposure reduction. The scenario wording points to that specific behavior: You need to ensure that users from each company can view only the data of their respective company., Why A is Wrong: a column encryption key is a security-related control, but its value depends on whether the requirement is identity, encryption, auditing, network isolation, or data exposure reduction. It is not the right enforcement point for this case; the scenario needs the control that governs the data or identity path being tested., Why B is Wrong: asymmetric keys is a security-related control, but its value depends on whether the requirement is identity, encryption, auditing, network isolation, or data exposure reduction. It does not satisfy the required identity, encryption, firewall, auditing, or data-exposure boundary described in the scenario: You need to ensure that users from each company can view only the data of their respective company., Why C is Wrong: a function is a security-related control, but its value depends on whether the requirement is identity, encryption, auditing, network isolation, or data exposure reduction. It protects or manages a different security layer, so the required database access or protection behavior would still be incomplete., ]

Which counter should you monitor for real-time processing to meet the technical requirements?

Options:

SU% Utilization

Data Conversion Errors

Buy Now

Answer:

Explanation:

Scenario: Real-time processing must be monitored to ensure that workloads are sized properly based on actual usage patterns.

To monitor the performance of a database in Azure SQL Database and Azure SQL Managed Instance, start by monitoring the CPU and IO resources used by your workload relative to the level of database performance you chose in selecting a particular service tier and performance level.

[Reference:, https://docs.microsoft.com/en-us/azure/azure-sql/database/monitor-tune-overview, , , , , , Basic Concept: This question tests Azure monitoring and performance management, including which metric, log destination, or alerting behavior fits the operational requirement., Why A is Correct: SU% Utilization is the Stream Analytics metric used to determine whether the job has enough streaming units for its workload. This fits the case because the requested outcome is: Which counter should you monitor for real-time processing to meet the technical requirements? The selected feature addresses that outcome directly rather than relying on a workaround., Why B is Wrong: CPU percentage is important for database compute monitoring, but it is not the Stream Analytics sizing metric when the question is about streaming units. It would produce a different operational signal than the one needed to investigate, alert, or tune the workload in this question., Why C is Wrong: Concurrent users is related to operational monitoring or tuning, but it must match the exact signal needed: query history, resource utilization, wait/blocking detail, or automatic remediation. It does not expose the required metric, query history, wait/blocking signal, or tuning mechanism; using it would not give the administrator the evidence requested., Why D is Wrong: Data Conversion Errors is related to operational monitoring or tuning, but it must match the exact signal needed: query history, resource utilization, wait/blocking detail, or automatic remediation. It is useful in other troubleshooting paths, but this scenario requires a more specific monitoring or optimization feature., Verification Note: The original listed answer was B; the corrected answer is A because For Azure Stream Analytics workload sizing, SU% Utilization is the service metric used to evaluate whether streaming units are appropriately sized., ]

[Reference:, https://docs.microsoft.com/en-us/azure/storage/blobs/storage-lifecycle-management-concepts, , , , , , , , Basic Concept: This question tests plan and configure a high availability and disaster recovery (ha/dr) environment in the DP-300 exam context. The correct choice is determined by the exact service boundary and operational requirement stated in the scenario., Why C is Correct: lifecycle management matches the expected DP-300 administration action. lifecycle management is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. The question is not asking for a general Azure capability; it is asking for the feature that produces this result: You need to design a data retention solution for the Twitter feed data records., Why A is Wrong: time-based retention is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. It does not meet the failover, restore, quorum, or cross-region continuity target stated in the question, even if it is valid in a different availability design., Why B is Wrong: change feed is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. It handles a different resilience pattern and would not deliver the failover or recovery behavior required here., Why D is Wrong: soft delete is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. It does not meet the failover, restore, quorum, or cross-region continuity target stated in the question, even if it is valid in a different availability design., ]

Options:

Buy Now

Answer:

See the explanation part for the complete Solution.

Explanation:

Create an Azure Private Endpoint for the Azure SQL logical server that hosts db1, place the private endpoint in VNET1, and integrate it with the private DNS zone:

privatelink.database.windows.net

This is the correct solution because Azure SQL Database is a PaaS service. You do not assign a private IP directly to db1. Instead, Azure creates a private endpoint network interface in the virtual network. That private endpoint receives a private IP address from a subnet in VNET1, and clients in VNET1 use that private IP path to reach the SQL server. Microsoft defines a private endpoint as a network interface that uses a private IP address from your virtual network to connect privately to a Private Link resource such as Azure SQL Database.

Azure Portal Method — Recommended for Simulation

Step 1: Identify the SQL logical server that hosts db1

Search for SQL databases.

Open db1.

On the database overview page, identify the Server name.

The private endpoint is created for the Azure SQL logical server, not for the database object alone. For Azure SQL Database, the Private Link resource type is:

Microsoft.Sql/servers

and the target subresource is:

sqlServer

Microsoft lists Azure SQL Database private endpoint DNS configuration under Microsoft.Sql/servers with subresource sqlServer.

Step 2: Open the SQL server networking page

Open the Azure SQL logical server that hosts db1.

In the left menu, go to:

Security > Networking

Select the Private access tab.

Select Create a private endpoint.

Microsoft’s Azure SQL private endpoint workflow is performed from the SQL server resource under Networking > Private access, where you can create or manage private endpoint connections.

Step 3: Configure the private endpoint basics

On the Create private endpoint page:

Setting

Value

Subscription

Use the lab subscription

Resource group

Use the lab resource group

Name

pe-db1-sql

Region

Same region as VNET1, if possible

The name is not exam-critical. The critical part is that the endpoint is associated with VNET1 and the SQL server that hosts db1.

Step 4: Configure the target resource

On the Resource tab, configure:

Setting

Value

Connection method

Connect to an Azure resource in my directory

Resource type

Microsoft.Sql/servers

Resource

SQL logical server that hosts db1

Target sub-resource

sqlServer

Do not choose storage, VM, managed instance, or any unrelated resource type. This is Azure SQL Database, so the target subresource must be sqlServer.

Step 5: Configure VNET1 and subnet

On the Virtual Network tab:

Setting

Value

Virtual network

VNET1

Subnet

Select an available subnet in VNET1

Private IP configuration

Dynamic is fine unless the lab requires static

Azure will create a network interface for the private endpoint and assign it a private IP address from the selected subnet. Microsoft notes that the network interface page for the private endpoint shows the private IP address assigned to the private endpoint connection.

Step 6: Configure private DNS integration

On the DNS tab:

Enable private DNS zone integration.

Use or create the private DNS zone:

privatelink.database.windows.net

Link the private DNS zone to:

VNET1

This is not optional in a clean exam solution. Without DNS integration, clients may still resolve the SQL server name to the public endpoint instead of the private endpoint. Microsoft states that DNS is critical because it resolves the private endpoint IP address, and for Azure SQL Database the recommended private DNS zone is privatelink.database.windows.net.

Step 7: Review and create

Select Review + create.

Confirm:

Resource: SQL logical server hosting db1

Target subresource: sqlServer

Virtual network: VNET1

Private DNS zone: privatelink.database.windows.net

Select Create.

After deployment, the SQL server will have a private endpoint connection associated with VNET1.

Step 8: Approve the private endpoint connection if required

In most same-directory deployments, approval may be automatic. If approval is pending:

Open the SQL logical server.

Go to:

Networking > Private access

Select the pending private endpoint connection.

Select Approve.

Microsoft documents that SQL administrators can approve or reject private endpoint connections from the SQL server private access page.

Step 9: Optional but recommended — Disable public network access

The task only says you need to connect by private IP from VNET1. It does not explicitly say to block public access. But if the exam expects private-only access, then disable public access after the private endpoint works.

On the SQL logical server:

Go to:

Security > Networking > Public access

Set Public network access to:

Disabled

or select:

Deny public network access

Save.

Be careful: Microsoft states that adding a private endpoint does not automatically block public routing to the logical server. Public access must be denied separately if you want private-only access.

How to Connect from SSMS

You should connect from a machine that is inside VNET1, such as an Azure VM joined to VNET1.

Step 1: Test DNS from a VM in VNET1

From a VM in VNET1, run:

nslookup < sql-server-name > .database.windows.net

Expected result: the name should resolve through the private endpoint path and return a private IP address from VNET1’s address space.

Microsoft explains that connection URLs do not change; DNS resolution is overridden so the existing service FQDN resolves to the private endpoint private IP address.

Step 2: Connect with SSMS

In SSMS, connect using the normal Azure SQL server name:

< sql-server-name > .database.windows.net

Then select database:

db1

Use normal SQL authentication or Microsoft Entra authentication.

Do not type the raw private IP address into SSMS unless the lab specifically forces it. For Azure SQL, the correct operational pattern is to connect to the SQL server FQDN and allow private DNS to resolve that FQDN to the private endpoint IP. Direct IP connection can cause TLS/certificate name problems because the server certificate matches the DNS name, not the private IP.

Verification

The task is complete when all of these are true:

Private endpoint exists for the SQL logical server hosting db1.

Target subresource is sqlServer.

The private endpoint is deployed into VNET1.

A private IP address is assigned to the private endpoint NIC.

Private DNS zone privatelink.database.windows.net exists.

The private DNS zone is linked to VNET1.

The SQL server FQDN resolves to the private endpoint private IP from inside VNET1.

SSMS can connect to db1 from a VM or client connected to VNET1.

Final Exam-Lab Action

Use the Azure portal and configure:

SQL server hosting db1

> Networking

> Private access

> Create private endpoint

Resource type: Microsoft.Sql/servers

Target subresource: sqlServer

Virtual network: VNET1

Private DNS zone: privatelink.database.windows.net

Then connect from a VM or client in VNET1 using:

< sql-server-name > .database.windows.net

That is the correct way to ensure db1 is reachable through a private IP address on VNET1.

Task 12

You need to configure high availability for dbl. The solution must tolerate the loss of an Azure datacenter without data loss or the need to modify application connection strings.

Options:

Buy Now

Answer:

See the explanation part for the complete Solution.

Explanation:

To configure high availability for dbl, you can use the failover groups feature of Azure SQL Database. Failover groups allow you to manage the replication and failover of a group of databases across different regions with the same connection strings1. You can choose all, or a subset of, user databases in a logical server to be replicated to another logical server in a different region. You can also specify the failover policy, such as manual or automatic, and the grace period for data loss.

Here are the steps to create a failover group for dbl:

Using the Azure portal:

Go to the Azure portal and select your Azure SQL Database server that hosts dbl.

Select Failover groups in the left menu and click on Add group.

Enter a name for the failover group and select a secondary region that is different from the primary region.

Click on Create a new server and enter the details for the secondary server, such as server name, admin login, password, and subscription.

Click on Select existing database(s) and choose dbl from the list of databases on the primary server.

Click on Configure failover policy and select the failover mode, grace period, and read-write failover endpoint mode according to your preferences.

Click on Create to create the failover group and start the replication of dbl to the secondary server.

Using PowerShell commands:

Install the Azure PowerShell module and log in with your Azure account.

Run the following command to create a new server in the secondary region: New-AzSqlServer -ResourceGroupName < your-resource-group-name > -ServerName < your-secondary-server-name > -Location " < secondary-region-name > " -SqlAdministratorCredentials $(New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList " < your-admin-login > " , $(ConvertTo-SecureString -String " < your-password > " -AsPlainText -Force))

Run the following command to create a new failover group with dbl: New-AzSqlDatabaseFailoverGroup -ResourceGroupName < your-resource-group-name > -ServerName < your-primary-server-name > -PartnerResourceGroupName < your-resource-group-name > -PartnerServerName < your-secondary-server-name > -FailoverGroupName < your-failover-group-name > -Database dbl -FailoverPolicy < manual-or-automatic > -GracePeriodWithDataLossHours < grace-period-in-hours > -ReadWriteFailoverEndpoint " < enabled-or-disabled > "

You can modify the parameters of the command according to your preferences, such as the failover policy, grace period, and read-write failover endpoint mode.

These are the steps to create a failover group for dbl

Task 5

You need to generate an email alert for db1 if the average CPU percentage utilization is greater than 50 percent for five minutes sampled at one-minute intervals. The alert must be sent to admin@contoso.com.

You may need to use SQL Server Management Studio and the Azure portal.

Options:

Buy Now

Answer:

See the explanation part for the complete Solution.

Explanation:

Create an Azure Monitor metric alert rule on database db1 using the metric:

CPU percentage

Configure the condition as:

Aggregation: Average

Operator: Greater than

Threshold: 50

Aggregation granularity / Period: 1 minute

Frequency of evaluation: 1 minute

Evaluation period / Lookback window: 5 minutes

Action group email: admin@contoso.com

Azure SQL Database exposes CPU percentage as a platform metric, and Azure Monitor metric alerts can send notifications through action groups such as email. Microsoft describes SQL Database alerts as metric-based alerts that can send email when metrics such as CPU usage reach a defined threshold.

Azure Portal Method — Recommended for Simulation

Step 1: Open the db1 Azure SQL database

Search for SQL databases.

Open the database named:

db1

Do not open the SQL logical server unless the alert needs to apply to all databases. This task is specifically for db1, so the alert scope must be the db1 database resource.

Step 2: Create a new alert rule

From the db1 database page:

In the left menu, select Alerts.

Select Create.

Select Alert rule.

Microsoft’s Azure Monitor workflow allows you to create an alert rule directly from the target resource. When you create it from a resource, the resource is automatically set as the alert scope.

Step 3: Confirm the alert scope

On the alert rule page, confirm the scope is the Azure SQL database:

db1

The resource type should be similar to:

SQL database

Microsoft.Sql/servers/databases

If the scope is the SQL server instead of the database, remove it and select the db1 database resource.

Step 4: Add the alert condition

Under Condition, select Add condition.

Choose the metric:

CPU percentage

Sometimes it appears as:

CPU percent

or metric name:

cpu_percent

For Azure SQL Database, CPU percentage represents CPU consumption toward the database workload limit, expressed as a percentage.

Step 5: Configure the signal logic

Configure the alert logic exactly like this:

Setting

Value

Threshold type

Static

Aggregation type

Average

Operator

Greater than

Threshold value

Unit

Percent

Aggregation granularity / Period

1 minute

Frequency of evaluation

1 minute

Evaluation period / Lookback window

5 minutes

This means Azure Monitor evaluates the CPU metric every minute, using one-minute metric samples, and fires the alert only when the average CPU percentage is greater than 50% across the five-minute evaluation window.

Be precise here. The task says:

average CPU percentage utilization is greater than 50 percent for five minutes sampled at one-minute intervals

So the correct choices are:

Average

Greater than 50

Every 1 minute

Over the last 5 minutes

Azure Monitor metric alert rules combine the monitored resource, the metric condition, and action groups that run when the condition is met.

Step 6: Create the email action group

Under Actions, select:

Create action group

Configure the basics:

Setting

Value

Subscription

Use the current subscription

Resource group

Use the lab resource group

Action group name

AG-db1-CPU-Email

Display name

db1CPU

Then go to Notifications.

Add a notification:

Setting

Value

Notification type

Email/SMS message/Push/Voice

Name

EmailAdmin

admin@contoso.com

Select OK, then Review + create, then Create.

Action groups define the notification or automation action that runs when an alert fires. Microsoft documents email as a supported action group notification type.

Step 7: Configure alert rule details

Under Details, configure:

Setting

Value

Severity

2 or 3

Alert rule name

db1 CPU greater than 50 percent

Description

Alert when average CPU percentage for db1 is greater than 50 percent for 5 minutes.

Enable upon creation

Yes

Severity is usually not specified by the task, so any reasonable severity is acceptable. In an exam lab, I would use Severity 2 for CPU performance impact.

Step 8: Review and create

Select Review + create.

Confirm the condition says something equivalent to:

Whenever the average CPU percentage is greater than 50

Confirm the evaluation settings are:

Check every 1 minute

Lookback period 5 minutes

Confirm the action group sends email to:

admin@contoso.com

Select Create.

Verification

After creation:

Open db1.

Go to Alerts.

Select Alert rules.

Confirm the alert rule exists and is enabled.

Open the rule and verify:

Scope: db1

Signal: CPU percentage

Aggregation: Average

Operator: Greater than

Threshold: 50

Evaluation frequency: 1 minute

Window size: 5 minutes

Action group: admin@contoso.com

Azure CLI Method

Use this only if the simulation gives you Cloud Shell.

First get the database resource ID:

az sql db show \

--resource-group < resource-group-name > \

--server < sql-server-name > \

--name db1 \

--query id \

--output tsv

Create the action group:

az monitor action-group create \

--resource-group < resource-group-name > \

--name AG-db1-CPU-Email \

--short-name db1CPU \

--action email EmailAdmin admin@contoso.com

Create the metric alert:

az monitor metrics alert create \

--name " db1 CPU greater than 50 percent " \

--resource-group < resource-group-name > \

--scopes < db1-resource-id > \

--condition " avg cpu_percent > 50 " \

--window-size 5m \

--evaluation-frequency 1m \

--action AG-db1-CPU-Email \

--description " Alert when average CPU percentage for db1 is greater than 50 percent for 5 minutes. "

The metric name commonly used for Azure SQL Database CPU percentage in CLI/ARM contexts is:

cpu_percent

SSMS Clarification

SSMS is not the correct tool for this task.

Do not configure Database Mail. Azure SQL Database does not use SQL Server Agent/Database Mail in the same way as SQL Server on a VM or SQL Managed Instance. This requirement is an Azure Monitor metric alert requirement.

Correct tool:

Azure portal > db1 > Alerts > Create alert rule

Wrong tool:

SSMS Database Mail

Final Exam-Lab Configuration

Use this exact configuration:

Resource: db1

Alert type: Metric alert

Metric: CPU percentage

Aggregation: Average

Operator: Greater than

Threshold: 50

Aggregation granularity: 1 minute

Evaluation frequency: 1 minute

Evaluation period/window: 5 minutes

Action group notification: Email

Email recipient: admin@contoso.com

That completes the task.

Task 9

You need to ensure that when non-administrative users query the SalesLT.Customer table in db1, email addresses are obscured. For example, an email address of alice@contoso.com must appear as aXXX@XXXX.com.

You may need to use SQL Server Management Studio and the Azure portal.

Options:

Buy Now

Answer:

See the explanation part for the complete Solution.

Explanation:

Configure Dynamic Data Masking on the email column in:

SalesLT.Customer

The column is normally:

EmailAddress

Use the built-in masking function:

email()

Microsoft documents that Dynamic Data Masking hides sensitive data in query results for nonprivileged users without changing the stored data. The built-in email() masking function exposes the first letter and returns the masked format aXXX@XXXX.com, which exactly matches the requirement.

Method 1 — SSMS / T-SQL Method

This is the fastest and most reliable method.

Step 1: Connect to db1

Open SQL Server Management Studio.

Connect to the Azure SQL logical server that hosts db1.

Open a query window against database:

db1

Step 2: Apply the email mask

Run:

ALTER TABLE [SalesLT].[Customer]

ALTER COLUMN [EmailAddress]

ADD MASKED WITH (FUNCTION = ' email() ' );

This adds a Dynamic Data Masking rule to the EmailAddress column. The actual email address remains stored in the table, but users without permission to view unmasked data will see the masked value. Microsoft’s documented syntax for adding an email mask is ALTER COLUMN Email ADD MASKED WITH (FUNCTION = ' email() ' ).

Step 3: Verify that the column is masked

Run:

SELECT

OBJECT_SCHEMA_NAME(mc.object_id) AS schema_name,

OBJECT_NAME(mc.object_id) AS table_name,

c.name AS column_name,

mc.masking_function

FROM sys.masked_columns AS mc

JOIN sys.columns AS c

ON mc.object_id = c.object_id

AND mc.column_id = c.column_id

WHERE OBJECT_SCHEMA_NAME(mc.object_id) = ' SalesLT '

AND OBJECT_NAME(mc.object_id) = ' Customer '

AND c.name = ' EmailAddress ' ;

Expected result:

schema_name SalesLT

table_name Customer

column_name EmailAddress

masking_function email()

Step 4: Test as a non-administrative user

If you have a test user, run:

EXECUTE AS USER = ' TestUser ' ;

SELECT TOP (10)

EmailAddress

FROM SalesLT.Customer;

REVERT;

Expected output should look like:

aXXX@XXXX.com

bXXX@XXXX.com

cXXX@XXXX.com

A user with administrative privileges, db_owner, or UNMASK permission can still see the original email value. Microsoft states that users with administrative rights such as server admin, Microsoft Entra admin, and db_owner can view the original unmasked data.

Method 2 — Azure Portal Method

Use this if the simulation expects portal configuration.

Step 1: Open db1

Search for SQL databases.

Open database:

db1

Step 2: Open Dynamic Data Masking

From the db1 page:

Security > Dynamic Data Masking

Microsoft states that for Azure SQL Database, Dynamic Data Masking can be configured in the Azure portal from the SQL database configuration pane under Security > Dynamic Data Masking.

Step 3: Add a masking rule

Add a mask for the email column:

Setting

Value

Schema

SalesLT

Table

Customer

Column

EmailAddress

Masking field format

Masking function

email()

Then select:

Save

The portal may show the mask type simply as:

That is the correct option because it maps to the email() masking function.

Important Permission Check

Dynamic Data Masking only affects users who do not have permission to view unmasked data.

If a non-administrative user was previously granted UNMASK, remove it:

REVOKE UNMASK TO [UserName];

Or, if a role was granted UNMASK, revoke it from the role:

REVOKE UNMASK TO [RoleName];

Do not grant UNMASK to normal users. UNMASK allows users to bypass masking and see the original values. Microsoft documents that UNMASK permission controls whether users can view masked or original data.

Final Exam-Lab Action

Run this against db1:

ALTER TABLE [SalesLT].[Customer]

ALTER COLUMN [EmailAddress]

ADD MASKED WITH (FUNCTION = ' email() ' );

Then verify:

SELECT

OBJECT_SCHEMA_NAME(object_id) AS schema_name,

OBJECT_NAME(object_id) AS table_name,

name AS column_name,

masking_function

FROM sys.masked_columns

WHERE OBJECT_SCHEMA_NAME(object_id) = ' SalesLT '

AND OBJECT_NAME(object_id) = ' Customer '

AND name = ' EmailAddress ' ;

The task is complete when non-administrative users querying SalesLT.Customer.EmailAddress see masked email values such as:

aXXX@XXXX.com

Task 8

You need to increase the maximum storage size of the query store on db1 to 4,000 MB You may need to use SQL Server Management Studio and the Azure portal.

Options:

Buy Now

Answer:

See the explanation part for the complete Solution.

Explanation:

Connect to db1 in SQL Server Management Studio and run:

ALTER DATABASE [db1]

SET QUERY_STORE (MAX_STORAGE_SIZE_MB = 4000);

Microsoft documents that Query Store maximum storage size is changed with:

ALTER DATABASE < database_name >

SET QUERY_STORE (MAX_STORAGE_SIZE_MB = < size > );

For Azure SQL Database, the maximum allowed MAX_STORAGE_SIZE_MB value is 10,240 MB, so 4,000 MB is valid.

Method 1 — SSMS / T-SQL Method

This is the cleanest method for the simulation.

Step 1: Open SQL Server Management Studio

Open SQL Server Management Studio.

Connect to the Azure SQL logical server that hosts db1.

Use SQL authentication or Microsoft Entra authentication.

In Connection Properties, select:

db1

You can also connect to master, but for this task it is cleaner to open a query window in db1.

Step 2: Run the Query Store configuration command

Open a new query window and run:

ALTER DATABASE [db1]

SET QUERY_STORE (MAX_STORAGE_SIZE_MB = 4000);

This changes the Query Store maximum allocated storage size to 4,000 MB.

Step 3: Verify the setting

Run this query in db1:

SELECT

actual_state_desc,

desired_state_desc,

current_storage_size_mb,

max_storage_size_mb

FROM sys.database_query_store_options;

Expected result:

max_storage_size_mb = 4000

Microsoft documents sys.database_query_store_options as the catalog view that returns Query Store configuration, including max_storage_size_mb.

Method 2 — SSMS Graphical Method

Use this if the simulation expects a GUI action.

Step 1: Connect to the server

Open SQL Server Management Studio.

Connect to the Azure SQL logical server.

Expand Databases.

Right-click db1.

Select Properties.

Step 2: Open Query Store settings

In the Database Properties window, select Query Store.

Find the setting:

Max Size (MB)

or:

Maximum Storage Size (MB)

Change the value to:

4000

Select OK.

Step 3: Verify

Run:

SELECT max_storage_size_mb

FROM sys.database_query_store_options;

Expected value:

4000

Azure Portal Clarification

The Azure portal is not the best tool for this specific Query Store configuration. Query Store size is a database engine setting, not a normal Azure resource setting like backup retention, locks, alerts, or private endpoints.

Use SSMS/T-SQL for this task.

Important Notes

Query Store must remain enabled

Do not disable Query Store. Azure SQL Database uses Query Store heavily, and Microsoft notes that Query Store is enabled by default for Azure SQL Database. The task only asks to increase the maximum storage size, not to change capture mode, cleanup policy, or operation mode.

4,000 MB is valid

Azure SQL Database allows Query Store MAX_STORAGE_SIZE_MB up to 10,240 MB, so this setting is within the allowed range.

Final Exam-Lab Action

Run this against db1:

ALTER DATABASE [db1]

SET QUERY_STORE (MAX_STORAGE_SIZE_MB = 4000);

Then verify with:

SELECT max_storage_size_mb

FROM sys.database_query_store_options;

The task is complete when the result shows:

4000

You need to configure a disaster recovery solution for db1. When a failover occurs, the connection strings to the database must remain the same. The secondary server must be in the West US 3 Azure region.

Options:

Buy Now

Answer:

See the explanation part for the complete Solution.

Explanation:

To configure a disaster recovery solution for db1, you can use the failover groups feature of Azure SQL Database. Failover groups allow you to manage the replication and failover of a group of databases across different regions with the same connection strings1. You can also use active geo-replication as an alternative, but you will need to update the connection strings manually after a failover2.

Here are the steps to create a failover group for db1 with the secondary server in the West US 3 region:

Using the Azure portal:

Go to the Azure portal and select your Azure SQL Database server that hosts db1.

Select Failover groups in the left menu and click on Add group.

Enter a name for the failover group and select West US 3 as the secondary region.

Click on Create a new server and enter the details for the secondary server, such as server name, admin login, password, and subscription.

Click on Select existing database(s) and choose db1 from the list of databases on the primary server.

Click on Configure failover policy and select the failover mode, grace period, and read-write failover endpoint mode according to your preferences.

Click on Create to create the failover group and start the replication of db1 to the secondary server.

Using PowerShell commands:

Install the Azure PowerShell module and log in with your Azure account.

Run the following command to create a new server in the West US 3 region: New-AzSqlServer -ResourceGroupName < your-resource-group-name > -ServerName < your-secondary-server-name > -Location " West US 3 " -SqlAdministratorCredentials $(New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList " < your-admin-login > " , $(ConvertTo-SecureString -String " < your-password > " -AsPlainText -Force))

Run the following command to create a new failover group with db1: New-AzSqlDatabaseFailoverGroup -ResourceGroupName < your-resource-group-name > -ServerName < your-primary-server-name > -PartnerResourceGroupName < your-resource-group-name > -PartnerServerName < your-secondary-server-name > -FailoverGroupName < your-failover-group-name > -Database db1 -FailoverPolicy Manual -GracePeriodWithDataLossHours 1 -ReadWriteFailoverEndpoint " Enabled "

You can modify the parameters of the command according to your preferences, such as the failover policy, grace period, and read-write failover endpoint mode.

These are the steps to create a failover group for db1 with the secondary server in the West US 3 region.

Answer:

See the explanation part for the complete Solution.

Explanation:

Enable Azure SQL Auditing at the server level on the Azure SQL logical server:

sql60152867

and configure the audit destination as the Azure Storage account:

sa60152867

This is the correct solution because the task says all databases on sql60152867. Database-level auditing would only apply to one database. Server-level auditing applies to all existing and newly created databases on the logical server. Microsoft states that server auditing policies apply to all existing and newly created databases on the server. The default auditing policy includes BATCH_COMPLETED_GROUP, which audits queries and stored procedures executed against the database, plus successful and failed authentication events.

Azure Portal Method — Recommended for Simulation

Step 1: Open the Azure SQL logical server

Search for:

SQL servers

Open the SQL logical server named:

sql60152867

Be careful with the name. In your prompt, it appears as sql60l 52867, but the earlier tasks strongly indicate the real server name is probably:

sql60152867

Use the SQL logical server that hosts the databases, not a single SQL database.

Step 2: Open Auditing

On the SQL server page:

In the left menu, go to Security.

Select Auditing.

Microsoft’s setup path is to navigate to Auditing under the Security heading in either the SQL database or SQL server pane. For this task, you must use the SQL server pane because the requirement covers all databases.

Step 3: Enable server-level auditing

Set:

Enable Azure SQL Auditing = On

or:

Auditing = On

depending on the portal wording.

This enables the server-level audit policy.

Step 4: Select Storage as the audit destination

Under Audit log destination, select:

Storage

Then choose the storage account:

sa60152867

Microsoft states that Azure SQL auditing can write database events to an Azure storage account, Log Analytics workspace, or Event Hubs. For this simulation, the destination must be the storage account sa60152867, so do not choose Log Analytics or Event Hub unless the task separately asks for them.

Step 5: Configure storage authentication

If the portal asks for authentication type, use one of these depending on what is available in the lab:

Option

Use when

Managed Identity

Preferred if available

Storage access keys

Use if the lab expects the older/default storage-key method

Microsoft recommends managed identity for storage authentication because storage access keys are a security risk. However, many exam simulations still accept the default storage-key flow as long as the audit destination is correctly set to the required storage account.

Step 6: Leave default audit action groups enabled

Do not remove the default audit action groups.

The default Azure SQL auditing policy includes:

BATCH_COMPLETED_GROUP

SUCCESSFUL_DATABASE_AUTHENTICATION_GROUP

FAILED_DATABASE_AUTHENTICATION_GROUP

BATCH_COMPLETED_GROUP is the key one here because it captures completed T-SQL batches, meaning the queries executed against the databases. Authentication and principal fields identify the login/user context. Microsoft states that the default auditing policy audits all queries and stored procedures executed against the database, plus successful and failed logins.

Step 7: Save the auditing configuration

Select:

Save

Wait for the portal notification that the auditing settings were saved successfully.

That completes the required configuration.

Verification

Verify from the Azure portal

Open the SQL server:

sql60152867

Go to:

Security > Auditing

Confirm:

Auditing: On

Destination: Storage

Storage account: sa60152867

Scope: Server-level

Verify storage output

After users execute queries, audit files should appear in the storage account.

Open storage account:

sa60152867

Go to Containers.

Open:

sqldbauditlogs

Azure SQL audit logs written to Azure Storage are stored in a container named sqldbauditlogs. Audit logs are written as .xel files and can be opened with SQL Server Management Studio.

What Information Is Captured?

The audit log includes the exact fields needed for this task.

Required information

Audit log field

Query executed

statement / statement_s

Database name

database_name / database_name_s

User context

database_principal_name / database_principal_name_s

server_principal_name / server_principal_name_s

Session principal

session_server_principal_name / session_server_principal_name_s

Time of execution

event_time / event_time_t

Client IP

client_ip / client_ip_s

Microsoft’s audit log format documents statement as the T-SQL statement that was executed, database_principal_name as the database user context, and server_principal_name as the current login.

SSMS Method — Viewing the Audit Logs

SSMS is not the main tool to enable Azure SQL auditing in this simulation, but it can be used to read the .xel audit files after they are written.

Step 1: Download or access the .xel files

From the storage account:

sa60152867 > Containers > sqldbauditlogs

Download the .xel audit file, or access it through supported tooling.

Step 2: Open the audit file in SSMS

Open SQL Server Management Studio.

Go to:

File > Open > File

Select the .xel audit file.

Review fields such as:

statement

database_principal_name

server_principal_name

database_name

event_time

client_ip

This verifies that the queries and the users that executed them are being captured.

Azure CLI Method

Use this only if Cloud Shell is available and you know the resource group names.

az sql server audit-policy update \

--resource-group < resource-group-name > \

--name sql60152867 \

--state Enabled \

--storage-account sa60152867

Depending on the environment, you may also need to specify the storage endpoint and access key, or use managed identity configuration. In the portal simulation, the UI normally handles this for you.

PowerShell Method

Use this if Azure PowerShell is available.

Set-AzSqlServerAudit `

-ResourceGroupName " < resource-group-name > " `

-ServerName " sql60152867 " `

-BlobStorageTargetState Enabled `

-StorageAccountResourceId " /subscriptions/ < subscription-id > /resourceGroups/ < storage-rg > /providers/Microsoft.Storage/storageAccounts/sa60152867 "

This configures auditing at the server level, which is the correct scope for all databases.

Final Exam-Lab Action

Configure this in the Azure portal:

SQL server: sql60152867

Security > Auditing

Auditing: On

Audit destination: Storage

Storage account: sa60152867

Default audit action groups: Enabled

Save

That captures queries and the users who executed them for all databases on the SQL logical server and stores the audit records in sa60152867.

Task 4

You need to encrypt the LastName column of the SalesLT.Customer table in db1 by using Always Encrypted. You must use the Windows Certificate Store. You may need to use SQL Server Management Studio and the Azure portal.

Options:

Buy Now

Answer:

See the explanation part for the complete Solution.

Explanation:

Use SQL Server Management Studio Always Encrypted Wizard and encrypt:

Database: db1

Schema: SalesLT

Table: Customer

Column: LastName

Encryption feature: Always Encrypted

Column master key store: Windows Certificate Store

Do not use Transparent Data Encryption. TDE encrypts the database at rest, but this task specifically requires Always Encrypted, which protects selected columns and keeps the encryption keys outside the database engine. Microsoft states that Always Encrypted uses column encryption keys to encrypt column data and column master keys to protect those column encryption keys. Column master keys are stored outside the database system, such as in the Windows certificate store.

Method 1 — SSMS Always Encrypted Wizard

This is the correct method for the simulation.

Step 1: Open SSMS and connect to Azure SQL Database

Open SQL Server Management Studio.

Connect to the Azure SQL logical server that hosts db1.

Use a SQL admin account or Microsoft Entra admin account.

In Options > Connection Properties, select database:

db1

Connect.

If SSMS cannot connect, go to the Azure portal and add your client IP address under the SQL server firewall/networking settings.

Step 2: Open the table column

In Object Explorer:

Expand Databases.

Expand db1.

Expand Tables.

Expand:

SalesLT.Customer

Expand Columns.

Locate:

LastName

Microsoft confirms that the Always Encrypted Wizard can be launched at the database, table, or individual column level. For one column, the cleanest path is to launch it directly from the column.

Step 3: Launch the Always Encrypted Wizard

Right-click the LastName column, then select:

Encrypt Column

or, depending on the SSMS version:

Always Encrypted Wizard

Alternative path:

Right-click db1 > Tasks > Always Encrypted Wizard

Then manually select:

SalesLT.Customer.LastName

Step 4: Select the LastName column for encryption

On the Column Selection page:

Find:

SalesLT.Customer.LastName

Select the checkbox for LastName.

Set the encryption type.

Use:

Randomized

unless the lab specifically requires searching or equality filtering on LastName.

Reason: Randomized encryption is stronger because identical plaintext values produce different ciphertext values. Deterministic encryption allows equality lookups, joins, grouping, and indexing, but leaks more pattern information because identical plaintext values produce identical encrypted values. Microsoft describes deterministic encryption as query-friendly but more pattern-revealing, while randomized encryption is more secure but does not support normal searching/grouping/joining without secure enclaves.

For this task, the requirement is only to encrypt the LastName column, so Randomized is the safer default.

Step 5: Choose or create a Column Encryption Key

For Encryption Key, select a new key such as:

CEK_Auto1

or create a new column encryption key if one does not already exist.

This is the key that encrypts the data in the LastName column. Microsoft states that a column encryption key encrypts the data in encrypted columns, and the column master key encrypts/protects the column encryption key.

Select Next.

Step 6: Configure the Column Master Key in Windows Certificate Store

On the key configuration page, create a new Column Master Key.

Use settings like:

Setting

Value

Column master key name

CMK_WindowsCert or default generated name

Key store

Windows Certificate Store

Certificate location

Current User

Certificate

Generate new certificate

Column encryption key

CEK_Auto1 or default generated CEK

In many SSMS versions, the wizard creates both:

CMK_Auto1

CEK_Auto1

That is acceptable as long as the CMK key store is Windows Certificate Store.

Microsoft states that SQL Server Management Studio supports column master keys stored in the Windows Certificate Store, and that a column master key can be a certificate stored in Windows Certificate Store.

Step 7: Run the wizard

On the final wizard pages:

Review the configuration.

Choose:

Proceed to finish now

or:

Run immediately

Select Finish.

SSMS will generate the column master key metadata, column encryption key metadata, and perform the data encryption operation. Microsoft explains that the wizard can encrypt selected columns and can generate a new column master key and column encryption key when needed.

During encryption, SSMS may temporarily create a new table, copy data, encrypt the selected column, and swap the table back, depending on whether secure enclaves are used. Microsoft notes that the wizard can move data out of the database and perform cryptographic operations inside the SSMS process when secure enclave in-place encryption is not used.

Verification Steps

Step 1: Confirm Always Encrypted metadata exists

Run this in db1:

SELECT

name,

key_store_provider_name,

key_path

FROM sys.column_master_keys;

You should see a column master key that uses the Windows certificate store provider.

Then run:

SELECT

name

FROM sys.column_encryption_keys;

You should see the column encryption key created by the wizard.

Step 2: Confirm LastName is encrypted

Run:

SELECT

t.name AS table_name,

c.name AS column_name,

c.encryption_type_desc,

cek.name AS column_encryption_key

FROM sys.columns AS c

JOIN sys.tables AS t

ON c.object_id = t.object_id

LEFT JOIN sys.column_encryption_keys AS cek

ON c.column_encryption_key_id = cek.column_encryption_key_id

WHERE t.name = ' Customer '

AND SCHEMA_NAME(t.schema_id) = ' SalesLT '

AND c.name = ' LastName ' ;

Expected result:

table_name: Customer

column_name: LastName

encryption_type_desc: RANDOMIZED

column_encryption_key: CEK_Auto1 or similar

If you selected deterministic encryption, the expected value will be:

DETERMINISTIC

The key requirement is that encryption_type_desc is no longer NULL.

Step 3: Test viewing the encrypted column

Open a new SSMS query connection without Always Encrypted enabled and run:

SELECT TOP 10 LastName

FROM SalesLT.Customer;

You should not see normal plaintext values.

Then reconnect with Always Encrypted enabled:

In SSMS, select Connect > Database Engine.

Select Options.

Go to Additional Connection Parameters.

Add:

Column Encryption Setting=Enabled

Connect again.

Run:

SELECT TOP 10 LastName

FROM SalesLT.Customer;

A client that has access to the Windows certificate/private key should be able to decrypt the values. Microsoft explains that the database stores encrypted data and key metadata, while client-side components with access to the column master key perform encryption and decryption.

Important Exam Notes

Do not choose Azure Key Vault

The task explicitly says:

You must use the Windows Certificate Store.

So the column master key should not be stored in Azure Key Vault.

Wrong:

Azure Key Vault

Correct:

Windows Certificate Store

Do not use TDE

TDE is not column-level Always Encrypted. It encrypts database files/logs at rest, but users and administrators querying the database still see plaintext if they have SQL permissions.

Correct technology:

Always Encrypted

Correct key store:

Windows Certificate Store

Correct target column:

SalesLT.Customer.LastName

Questions 63

Task 2

You need to configure differential backups for the db1 Azure SQL database to be once a day instead of twice day. You may need to use SQL Server Management Studio and the Azure portal.

Options:

Buy Now

Answer:

See the explanation part for the complete Solution.

Explanation:

Requirement: Configure differential backups for Azure SQL Database db1 to run once a day instead of twice a day.

Correct setting: Change Differential backup frequency from 12 Hours to 24 Hours.

Azure SQL Database supports differential backup frequency of either 12 hours or 24 hours. A 12-hour frequency means twice per day; a 24-hour frequency means once per day. Microsoft also notes that 24-hour differential backup frequency can increase restore time compared with 12-hour frequency.

Method 1 — Azure Portal Method

This is the best method for the simulation.

Step 1: Open the Azure SQL logical server

Search for SQL servers.

Open the logical SQL server that hosts database db1.

Do not start from SQL Server Management Studio for this task. The differential backup frequency is an Azure SQL backup policy setting, not a normal T-SQL database setting.

Step 2: Open the Backups page

In the SQL server left menu, select Backups.

Select the Retention policies tab.

Microsoft’s documented portal path is to go to the logical SQL server, select Backups, then select the Retention policies tab.

Step 3: Select database db1

In the list of databases, locate db1.

Select the checkbox next to db1.

Select Configure policies from the action bar.

Step 4: Change the differential backup frequency

In the policy configuration pane:

Find Differential backup frequency.

Change it from:

12 Hours

to:

24 Hours

Leave the PITR retention period unchanged unless the task specifically tells you to change it.

Select Apply or Save.

Microsoft’s documented option is exactly 12 Hours or 24 hours under Differential backup frequency.

Method 2 — Azure CLI Method

Use this if the simulation provides Cloud Shell.

az sql db str-policy set \

--resource-group < resource-group-name > \

--server < server-name > \

--name db1 \

--retention-days < current-retention-days > \

--diffbackup-hours 24

Example:

az sql db str-policy set \

--resource-group RG1 \

--server sql60152867 \

--name db1 \

--retention-days 7 \

--diffbackup-hours 24

Microsoft documents az sql db str-policy set with --diffbackup-hours 24 for changing active database differential backup frequency. Valid values are 12 or 24 hours.

Be careful: do not guess the retention days blindly in a real environment. In the exam lab, use the existing retention value shown in the portal unless the task also asks you to change retention.

Method 3 — PowerShell Method

Use this if Azure PowerShell is available.

Set-AzSqlDatabaseBackupShortTermRetentionPolicy `

-ResourceGroupName " < resource-group-name > " `

-ServerName " < server-name > " `

-DatabaseName " db1 " `

-RetentionDays < current-retention-days > `

-DiffBackupIntervalInHours 24

Microsoft documents Set-AzSqlDatabaseBackupShortTermRetentionPolicy with -DiffBackupIntervalInHours 24 for setting Azure SQL Database differential backup frequency.

SSMS / T-SQL Clarification

For this task, SSMS is not the right tool to change the setting.

There is no normal ALTER DATABASE T-SQL command in Azure SQL Database to change automated differential backup frequency. Microsoft documents this change through:

Azure portal

Azure CLI

PowerShell

REST API

not SSMS/T-SQL.

You may use SSMS only to confirm the database exists and is accessible, but the backup frequency setting must be changed from Azure management tools.
