NSE6_FAZ-7.2 Sample Questions Answers

When you move a registered logging device from one ADOM (Administrative Domain) to another in FortiAnalyzer, it's essential to ensure that the analytical logs for the moved device are available in the new ADOM to maintain continuity in reporting and log analysis. The commandexecute sql-local rebuild-adom <new-ADOM-name>is used specifically for this purpose. Running this command populates the new ADOM with the analytical logs of the moved device, enabling you to generate accurate and comprehensive reports based on the historical data of the device in its new ADOM context. This process ensures that the transition of devices between ADOMs does not lead to a loss of analytical insight or reporting capabilities for the device's traffic and events.

In aggregation mode, FortiAnalyzer stores logs received from devices and forwards them at a specified time each day to avoid duplication. It is specifically designed to work between two FortiAnalyzer units and does not support syslog or CEF servers. Additionally, aggregation mode configurations are limited to CLI commandslog-forwardandlog-forward-service.References:FortiAnalyzer 7.2 Administrator Guide, "Aggregation" and "CLI Commands for Aggregation Mode" sections.

The processlogfiledin FortiGate units with an SSD disk is responsible for buffering logs when FortiAnalyzer is unreachable. If the connection to FortiAnalyzer is lost and the memory log buffer is full,logfiledallows logs to be buffered on disk. These logs are then sent to FortiAnalyzer once the connection is restored. This reliable logging mechanism ensures that logs are not lost during periods when FortiAnalyzer is not reachable, thereby maintaining log integrity and continuity.References:FortiOS 7.4.1 Administration Guide, "Log Buffering" and "Reliable Logging" sections.

The FortiAnalyzer commandexecute factory-resetis used to erase all device settings, images, databases, and logs on disk but preserves the current IP address and route information. This command effectively resets the FortiAnalyzer to its factory settings while maintaining its network configuration, allowing it to be quickly reconfigured with the same network settings.References:FortiAnalyzer 7.4.1 Administration Guide, "Reset Commands" section.

The purpose of executing the provided CLI commands, which include setting thelog-checksumtomd5-auth, is to ensure the integrity of the log files. This setting is used to record the MD5 hash value of log files, which is a widely used cryptographic hash function that produces a 128-bit (16-byte) hash value. By using MD5 authentication, FortiAnalyzer ensures that the log files have not been altered or tampered with during transit, thereby verifying their integrity upon receipt.This is not related to encrypting log transfers, scheduling reports, or creating secure channels for OFTP (Over-the-FortiGate Protocol) processes.

For HA on FortiAnalyzer, Log Data Sync ensures real-time log synchronization among all cluster members, including backup devices. This feature is enabled by default. The Initial Logs Sync state is triggered when a new unit is added to an HA cluster, where the primary unit synchronizes its logs with the newly added unit. After the initial synchronization, the secondary unit reboots and rebuilds its log database with the synchronized logs.References:FortiAnalyzer 7.2 Administrator Guide, "Log synchronization" section.
