Scenario: A Citrix Administrator configured an authentication, authorization, and auditing (AAA) policy to allow
users access through the Citrix ADC. The administrator bound the policy to a specific vServer.
Which policy expression will allow all users access through the vServer?
Tricky one, this is for 13.1 and classic still is mandatory for AAA until 2023 (with exceptions on Traffic policy) https://docs.citrix.com/en-us/citrix-adc/current-release/appexpert/policies-and-expressions/introduction-to-policies-and-exp/advanced-policy-infrastructure.html
Scenario: A Citrix Administrator manages a Citrix SDX appliance with several instances configured. The administrator needs to enable Layer 2 mode on two instances.
When using a shared network interface, what must the administrator do to ensure that traffic flows correctly?
Scenario: A Citrix Administrator is managing a Citrix ADC SDX running eight Citrix ADC instances. The administrator needs to upgrade the firmware on the instances. However, the administrator is concerned that it needs to be done simultaneously.
What upgrading flexibility does SDX provide in this scenario?
Scenario: A Citrix Administrator gives permissions to team members to access their own admin partition. This will allow them to add resources for different departments and manage them without making changes to the default Citrix ADC partition and configuration.
One team member typing to use the command line interface (CLI) to troubleshoot an authentication issue could NOT use aaad.debug. However, the team member has full permissions on the admin partition.
What can be the cause of this issue?
A Citrix Administrator receives user complaints about latency while accessing an application that is load balanced on the Citrix ADC.
Which tool can the administrator use to gather information regarding response time, client network latency, and server-side processing time?
Correct Answer: A. Citrix Application Delivery Management (ADM)
Short Explanation with reference: Citrix Application Delivery Management (ADM) is a web-based tool that provides end-to-end visibility and management for Citrix ADC deployments. It also enables administrators to view real-time and historical data on response time, client network latency, and server-side processing time for applications that are load balanced on the Citrix ADC1. HDX Insight, WAN Insight, and Security Insight are features of Citrix ADM that provide specific insights for HDX traffic, WAN optimization, and security events respectively1. They are not standalone tools that can be used to gather information on latency and response time. Therefore, the correct answer is A. Citrix Application Delivery Management (ADM).
Scenario: A Citrix Administrator is managing a Citrix Gateway with a standard Platform license and remote employees in the environment. The administrator wants to increase access by 3,000 users through the Citrix Gateway using VPN access.
Which license should the administrator recommend purchasing?
If a policy evaluates as_________________ a Citrix ADC performs the action assigned to the ____________ condition and stops further policy evaluation.
In a global server load balancing (GSLB) active-active environment, the connection proxy is used as the site persistence method.
What is used to source the traffic when the connection is proxied?
Which step can a Citrix Administrator take to use default compression policies?
To put a compression policy into effect, you must bind it either globally, so that it applies to all traffic that flows through the Citrix ADC, or to a specific virtual server, so that the policy applies only to requests whose destination is the VIP address of that virtual server.
By default, compression is disabled on the Citrix ADC. You must enable the feature before configuring it. You can enable it globally so that it applies to all HTTP and SSL services, or you can enable it just for specific services.
Scenario: A Citrix Administrator manages an environment that has three SSL websites, all serving the same content.
The administrator would like to consolidate the websites into a single, load-balanced SSL vServer.
What can the administrator bind to use a single SSL vServer?
Scenario: A Citrix Administrator currently manages a Citrix ADC environment for a growing retail company that may soon double its business volume. A Citrix ADC MPX 5901 is currently handling web and SSL transactions, but is close to full capacity. Due to the forecasted growth, the administrator needs to find a cost-effective solution.
What cost-effective recommendation can the administrator provide to management to handle the growth?
Scenario: The Citrix Administrator of a Linux environment needs to load balance the web servers. Due to budget constraints, the administrator is NOT able to implement a full-scale solution.
What can the administrator purchase and install to load balance the webservers?
it is the CPX, which is not a full scale solution. You don´t need a full virtual like VPX to run CPX inside Docker for Linux, that is the budget choice.
Scenario: A Citrix Administrator executed the command below:
> set httpcallout httpcallout1 –cacheForSecs 120
This command changes the cache duration of the HTTP ____________ to be set to 120 seconds. (Choose the
correct option to complete the sentence.)
A Citrix Administrator needs to confirm that all client certificates presented to the authentication vServer are valid until the year 2023.
Which expression can the administrator use to meet this requirement?
To improve page-rendering time a Citrix Administrator needs to overcome the connection limitation by enabling client browsers to simultaneously download more resources.
What should the administrator enable while configuring the front end optimization (FEO) feature?
A Citrix Administrator wants to configure independent and isolated access on a single appliance to allow three different departments to manage and isolate their own applications.
What can the administrator configure to isolate department-level administration?
Correct Answer: A. Admin partitions that use dedicated VLANs
Short Explanation with reference: Admin partitions are a feature of Citrix ADC that allow administrators to create multiple logical partitions on a single physical appliance. Each partition is independent and isolated from the others, and has its own configuration, resources, and management. This enables administrators to delegate administration tasks to different departments or customers, while maintaining security and operational consistency1. Admin partitions can use dedicated VLANs to isolate the network traffic of each partition from the others2. A SNIP in each partition, and bind a VLAN for the department (option B) is also a valid way to isolate network traffic, but it does not provide configuration and management isolation. Policy-based routes for each department in the nsroot partition (option C) and dedicated routes in the admin partitions for each department (option D) are not relevant for isolating department-level administration, as they are used for routing traffic based on policies or routes3. Therefore, the correct answer is A. Admin partitions that use dedicated VLANs.
Scenario: A Citrix Administrator observes that when the client gets redirected to www.citrix.com/owa/search?q=username, an HTTP 503 response is received from the content switching vServer.
The relevant configuration is as follows:
> add cs action CS_Act_1 -targetLBVserver SERVER_1
> add cs action CS_Act_2 -targetLBVserver SERVER_2
> add cs action CS_Act_3 -targetLBVserver SERVER_3
> add cs action CS_Act_4 -targetLBVserver SERVER_4
> add cs policy CS_Pol_1 -rule "http.REQ.URL path_and_queryCONTAINS(\"connect\")" -action CS_Act_1
> add cs policy CS_Pol_2 -rule "http.REQ.URL path_and_query EQ(\"owa\")" -action CS_Act_2
> add cs policy CS_Pol_3 -rule "http REQ.URL path_and_query CONTAINS(\"owa\")" -action CS_Act_3
> add cs policy CS_Pol_4 -rule "http.REQ.IS_VALID" -action CS_Act_4
> bind cs vServer CS_vserver1 -policyName CS_Pol_1 -priority 110
> bind cs vServer CS_vserver1 -policyName CS_Pol_4 -priority 120
How can the administrator correct the issue?
Scenario: Client connections to certain vServers are abnormally high. A Citrix Administrator needs to be alerted whenever the connections pass a certain threshold.
How can the administrator use Citrix Application Delivery Management (ADM) to accomplish this?
The correct answer is D. Configure specific alerts for vServers using Citrix ADM.
Short Explanation with reference: Citrix Application Delivery Management (ADM) is a web-based tool that provides end-to-end visibility and management for Citrix ADC deployments. It also enables administrators to view real-time and historical data on response time, client network latency, and server-side processing time for applications that are load balanced on the Citrix ADC1. Citrix ADM allows administrators to create thresholds and alerts to monitor the state of a Citrix ADC instance, entity, or counter. When the value of a counter exceeds the threshold, Citrix ADM generates an event to signify a performance-related issue, and performs an action such as sending an alert, email, or SMS notification1.
To configure specific alerts for vServers using Citrix ADM, administrators need to follow these steps1:
The other options are incorrect because they either do not allow setting specific thresholds and alerts for vServers, or they are used for different purposes. Network reporting (option A) and SMTP reporting (option B) are features of Citrix ADM that enable administrators to generate and send reports on network performance and statistics2. They do not allow setting thresholds and alerts for vServers. TCP Insight (option C) is a feature of Citrix ADM that provides detailed analytics of TCP traffic passing through the Citrix ADC instances3. It does not allow setting thresholds and alerts for vServers. Therefore, the correct answer is D. Configure specific alerts for vServers using Citrix ADM.
Scenario: A Citrix Administrator manages an environment that has an externally accessible website. The administrator would like to provide end-to-end encryption and use features such as caching and compression on the Citrix ADC.
Which setting should the administrator configure to meet this requirement?
Which mode on a Citrix ADC can a Citrix Administrator utilize to avoid asymmetrical packet flows and multiple route/ARP lookups?
Correct Answer: A. MAC-based forwarding (MBF)
Short Explanation with reference:
MAC-based forwarding (MBF) is a mode on a Citrix ADC that can be used to avoid asymmetrical packet flows and multiple route/ARP lookups. MBF enables the Citrix ADC to forward packets based on the MAC address of the destination server, instead of the IP address. This way, the Citrix ADC does not need to perform routing or ARP resolution for each packet, which reduces the processing overhead and improves performance. MBF also ensures that the return traffic from the server follows the same path as the incoming traffic from the client, which avoids asymmetrical routing issues.
MBF can be enabled on a Citrix ADC by using the GUI or the CLI of the appliance. MBF can be applied to a specific service or a service group, or to all services on the appliance. MBF can also be used in conjunction with other features, such as direct server return (DSR) and link load balancing (LLB).
Therefore, option A is the correct answer.
Scenario: A Citrix Administrator suspects an attack on a load-balancing vServer (IP address 192.168.100.25).
The administrator needs to restrict access to this vServer for 10 minutes.
Which Access Control List (ACL) will accomplish this?
By binding a multiple SAN certificate, we only need to adapt the DNS entries of the websites to point to the same IP (1 IP with 3 DNS) and we will be able to forward the requests to any backend server since all of them are serving the same content.
A Citrix Administrator configured global server load balancing (GSLB) for www.citrix.com, with two ADNS services named Citrix ADC 1 and Citrix ADC 2 in the setup.
Which record does the administrator need to add on the parent DNS server to delegate requests from www.citrix.com to Citrix ADC 1 and Citrix ADC 2?
set gslb vServer-GSLB-1-MIR ENABLED
What will the Citrix ADC appliance send when the above command is executed?
"if you enable multiple IP responses (MIR), the Citrix ADC appliance sends the best GSLB service as the first record in the response and adds the remaining active services as extra records. "
Scenario: While using the GUI, a Citrix ADC MPX appliance becomes unresponsive. A Citrix Administrator needs to restart the appliance and force a core dump for analysis.
What can the administrator do to accomplish this?
Scenario: After deploying a Citrix ADC in production, a Citrix Administrator notices that client requests are NOT being evenly distributed among backend resources. The administrator wants to change from the default loadbalancing method to one that will help distribute the load more evenly.
Which load-balancing method would ensure that the server with the least amount of network utilization is receiving new connections?
Scenario: A Citrix Administrator is running an e-commerce web service that uses backend SQL and RADIUS servers. The e-commerce platform runs on a web server using port 80, and a website status page on port 99 reports the status of all servers.
Which monitor should the administrator choose to confirm the availability of the e-commerce solution?
destPort TCP or UDP port to which to send the probe. If the parameter is set to 0, the port number of the service to which the monitor is bound is considered the destination port. For a monitor of type USER, however, the destination port is the port number that is included in the HTTP request sent to the dispatcher. Does not apply to monitors of type PING.
Scenario: A load-balancing vServer is configured to utilize the least bandwidth load-balancing method. A service attached to this vServer is brought into the effective state during production hours.
During the startup of a vServer, which load-balancing method is used by default?
During startup of a virtual server, or whenever the state of a virtual server changes, the virtual server can initially use the round-robin method to distribute the client requests among the physical servers. This type of distribution, referred to as startup round robin, helps prevent unnecessary load on a single server as the initial requests are served. After using the round-robin method at the startup, the virtual server switches to the loadbalancing method specified on the virtual server
Correct Answer: D. Round-robin
Short Explanation with reference:
A load-balancing vServer is a virtual server that distributes the incoming traffic among a group of services that provide the same content or functionality. A load-balancing vServer can use different load-balancing methods to select the best service for each request, based on various criteria, such as availability, performance, or load. The least bandwidth load-balancing method selects the service that is currently handling the least amount of traffic, measured in megabits per second.
However, during the startup of a vServer, the least bandwidth load-balancing method is not used by default. This is because the Citrix ADC appliance does not have enough data to calculate the bandwidth usage of each service at the beginning. Therefore, the appliance uses the round-robin load-balancing method by default, which selects the services in a circular order, without any weighting or priority. The round-robin load-balancing method is also used as a fallback method when other load-balancing methods fail or are not applicable.
Therefore, the correct answer is D. Round-robin.
