Question 2

Explanation

The correct answer is:

D. Shut down FortiAnalyzer and then replace the disk.

Explanation:

When using software RAID on FortiAnalyzer, the recommended approach after a disk failure is to shut down the system before replacing the faulty disk. This ensures that the RAID array is properly managed, and no data corruption or additional issues arise during the disk replacement. Unlike hardware RAID, which may support hot swapping, software RAID often requires a more cautious approach and typically recommends a system shutdown to ensure stability during the disk replacement process.

Why the Other Options Are Incorrect:

• A. Downgrade your RAID level, replace the disk, and then upgrade your RAID level: Downgrading the RAID level is unnecessary and complicated. It’s not a standard practice for replacing a failed disk and could complicate the system’s integrity and performance.

• B. Perform a hot swap: Software RAID typically does not support hot swapping as smoothly as hardware RAID. It’s safer to shut down the device and replace the disk.

• C. Clear all RAID alarms and replace the disk while FortiAnalyzer is still running: Clearing alarms does not address the underlying issue of the failed disk. Replacing the disk while the system is running is risky, as it can lead to data corruption in software RAID configurations.

Thus, D is the safest and recommended method for replacing the disk in a software RAID setup on FortiAnalyzer.
