CompTIA A+ Core 1 (220-1101) — Question 242

A technician is replacing a failed drive in a RAID 5 array. Which of the following is the first step the technician should take before hot swapping the drive out of the array?

Answer options

• A. Document the replacement date.
• B. Shut down the array.
• C. Safely dispose of the failed drive.
• D. Perform a full backup.

Correct answer: D

Explanation

The correct answer is D, as performing a full backup ensures that all data is secured before any changes are made to the array. Options A, B, and C are important steps but do not provide the necessary data protection that a backup offers before replacing the drive.
