CompTIA A+ Core 1 (220-1201) — Question 32

A technician is working on a RAID 1 array that is apparently degraded. The technician verifies the RAM and power are both operating as expected. Which of the following can the technician do to further isolate the issue?

Answer options

• A. Perform individual drive diagnostics.
• B. Run the chkdsk /f command.
• C. Rebuild the RAID array.
• D. Reconfigure the array as RAID 0.

Correct answer: A

Explanation

Performing individual drive diagnostics is the most effective way to determine which specific drive in the RAID 1 array may be causing the degradation. The chkdsk /f command is useful for checking file system errors, but it does not address hardware issues. Rebuilding the RAID array or reconfiguring it to RAID 0 would not help isolate the problem and could lead to further data loss.
