CompTIA A+ Core 1 (220-1201) — Question 45

A high-end workstation with a RAID 5 array is exhibiting slow data access speeds and occasional errors when retrieving files. The technician investigates further and notices one of the hard drives in the RAID array has an amber light. Which of the following steps should the technician take to troubleshoot and resolve the issues?

Answer options

• A. Review network issues that might be causing slow speeds.
• B. Upgrade all RAID drives to higher capacity models to increase data access speeds.
• C. Replace the failing drive, and then allow the RAID controller to rebuild the array.
• D. Reformat all drives in the RAID array to clear any software issues that might be causing the errors.

Correct answer: C

Explanation

The correct answer is C because replacing the failing drive is essential for restoring the RAID array's integrity and performance. Options A and B do not address the specific issue of the failing drive, while option D could result in data loss and does not address the underlying problem with the RAID array.
