CompTIA A+ Core 1 (220-1001) — Question 359

A high-end workstation is operating as expected, but two of the four SATA drives are displaying solid fault lights.
Which of the following is the MOST likely reason for this issue?

Answer options

• A. RAID 5 is being used.
• B. The RAID level of the disk array is 10.
• C. An M.2 boot device is being used.
• D. The RAID controller cache is turned on.

Correct answer: D

Explanation

The correct answer is D because having the RAID controller cache turned on can lead to fault lights if there's a discrepancy in data integrity or communication issues. Option A is incorrect as RAID 5 typically manages drive failures better. Option B is also not applicable since RAID 10 would provide redundancy for the drives. Option C is unrelated to the issue with SATA drives showing fault lights.
