NSE 5 – FortiAnalyzer 6.4 — Question 2

You are using RAID with a FortiAnalyzer that supports software RAID, and one of the hard disks on FortiAnalyzer has failed.
What is the recommended method to replace the disk?

Answer options

• A. Downgrade your RAID level, replace the disk, and then upgrade your RAID level.
• B. Perform a hot swap.
• C. Clear all RAID alarms and replace the disk while FortiAnalyzer is still running.
• D. Shut down FortiAnalyzer and then replace the disk.

Correct answer: D

Explanation

The correct answer is D because shutting down the FortiAnalyzer ensures that the system is in a safe state to replace the disk without risking data loss. Option A is incorrect as downgrading the RAID level is unnecessary and could introduce additional risk. Option B is not applicable in this case, as hot swapping may not be supported for the specific RAID configuration. Option C is also incorrect since replacing the disk while the system is running could lead to further complications or data corruption.
