NSE6_FAZ-7.2 Fortinet NSE 6 - FortiAnalyzer 7.2 Administrator Questions and Answers

The amount of reserved disk space required by FortiAnalyzer is influenced by the disk size and the RAID level. The system reserves a portion of the disk space for system use and unexpected quota overflow, with the rest available for device allocation. The RAID level determines the disk size and the reserved disk quota level, with different RAID configurations leading to variations in the reserved space.References:FortiAnalyzer 7.2 Administrator Guide, "Disk Space Allocation" and "RAID Level Impact" 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.

In a FortiAnalyzer Fabric, the FortiAnalyzer can recognize a Security Fabric group of devices, and it supports the Security Fabric by storing and analyzing logs from these units as if they were from a single device. The members of the Security Fabric group send their logs to the FortiAnalyzer, which acts as a supervisor for log storage and analysis, providing a centralized point of visibility and control over the logs.References:FortiAnalyzer 7.4.1 Administration Guide, "Security Fabric" section.

The default operating mode for FortiAnalyzer is analyzer mode. In this mode, FortiAnalyzer provides full functionality for event management and reporting features. This mode is intended for environments where comprehensive analysis and reporting are required. It allows FortiAnalyzer to collect, analyze, and store logs, as well as generate reports and manage events.References:FortiAnalyzer 7.4.1 Administration Guide, "Operating modes" section.

Based on the provided exhibit, which shows partial outputs of the system status and global settings for FortiAnalyzer devices, the devices cannot be configured as peers in an HA (High Availability) cluster. This is indicated by the HA Mode status being set to 'Stand Alone' for the displayed FortiAnalyzer device. For devices to be part of an HA cluster, they would need to havecompatible HA configurations, and usually, they should not be in 'Stand Alone' mode. Additionally, the exhibit only shows information for one FortiAnalyzer, so it cannot be determined if there is another device ready to form an HA cluster with it.

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.
