CompTIA A+ Core 1 (220-1001) — Question 105

A workstation has RAID 1 and RAID 5 arrays. Although performance is not degraded, management software is reporting a hard disk failure.
Which of the following should a technician do NEXT?

Answer options

• A. Check one of the RAID 1 disks for failure
• B. Rebuild the RAID 1 disks for failure
• C. Check one of the RAID 5 disks for failure
• D. Rebuild the RAID 5 array

Correct answer: A

Explanation

The correct action is to check one of the RAID 1 disks for failure because RAID 1 mirrors data, and if one disk fails, it needs to be identified first. Rebuilding the RAID 1 disks or checking the RAID 5 disks is premature if the specific failure has not been identified. Rebuilding the RAID 5 array is unnecessary since the RAID 1 configuration is likely where the issue lies.
