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

Regarding ADOMs (Administrative Domains) in FortiAnalyzer, a fabric ADOM is capable of including all device types that FortiAnalyzer supports. This is part of the flexibility offered by ADOMs to manage and report on logs from various devices within a Fortinet security fabric. ADOMs can be enabled to support non-FortiGate devices as well, and the root ADOM in Fabric ADOMs provides visibility into all Security Fabric devices. Additionally, it should be noted that in normal mode, you cannot assign different FortiGate VDOMs to different ADOMs, while in advanced mode, you can, which provides a more granular control over the log data from individual VDOMs.References:FortiAnalyzer 7.4.1 Administration Guide, "ADOMs" and "ADOM device modes" sections.

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.

In an HA cluster, the firmware upgrade process involves upgrading the secondary devices first. This approach ensures that the primary device can continue to handle traffic and maintain the operational stability of the network while the secondary devices are being upgraded. Once the secondary devices have successfully upgraded their firmware and are operational, the primary device can then be upgraded. This method minimizes downtime and maintains network integrity during the upgrade process.

When upgrading firmware in a High Availability (HA) cluster of FortiAnalyzer units, the recommended practice is to first upgrade the secondary devices before upgrading the primary device. This approach ensures that the primary device, which coordinates the cluster's operations, remains functional for as long as possible, minimizing the impact on log collection and analysis. Once the secondary devices are successfully upgraded and operational, the primary device can be upgraded, ensuring a smooth transition and maintaining continuous operation of the cluster.References:FortiAnalyzer 7.2 Administrator Guide - "System Administration" and "High Availability" sections.

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.

In systems that support hardware RAID, hot swapping allows for the replacement of a failed disk without shutting down the system. This capability is crucial for maintaining uptime and ensuring data redundancy and availability, especially in critical environments. The RAID controller rebuilds the data on the new disk using redundancy data from the other disks in the array, ensuring no data loss and minimal impact on system performance.

In the context of a FortiAnalyzer unit equipped with hardware RAID support, the optimal approach to addressing a hard disk failure is to perform a hot swap of the disk. Hardware RAID configurations are designed to provide redundancy and fault tolerance, allowing for the replacement of a failed disk without the need to shut down the system. Hot swapping enables the administrator to replace the faulty disk with a new one while the system is still running, and the RAID controller will rebuild the data on the new disk, restoring the RAID array to its fully operational state.References:FortiAnalyzer 7.2 Administrator Guide - "Hardware Maintenance" and "RAID Management" sections.

Fabric connectors in FortiAnalyzer, such as security fabric connectors (e.g., FortiClient EMS, FortiMail, FortiCASB) and storage connectors (e.g., Amazon S3, Azure Blob Container, Google Cloud Storage), provide efficient integration and data sharing capabilities. Using fabricconnectors for direct integration with FortiAnalyzer is more efficient and reliable than relying on third-party applications to poll information through the FortiAnalyzer API. Additionally, the ability to send logs to cloud storage platforms like Amazon S3, Azure Blob, and Google Cloud directly through storage connectors is a built-in feature that does not require an additional license, thus saving on storage costs and improving redundancy without incurring extra licensing fees.References:FortiAnalyzer 7.4.1 Administration Guide, "Fabric Connectors" and "Storage connectors" sections.
