CompTIA Server+ (SK0-005) — Question 324

An administrator needs to increase the size of an existing RAID 6 array that is running out of available space. Which of the following is the BEST way the administrator can perform this task?

Answer options

• A. Replace all the array drives at once and then expand the array.
• B. Expand the array by changing the RAID level to 6.
• C. Expand the array by changing the RAID level to 10.
• D. Replace the array drives one at a time and then expand the array.

Correct answer: D

Explanation

The correct answer is D because replacing the drives one by one allows the RAID 6 array to remain functional throughout the process, ensuring data integrity. Options A, B, and C are incorrect because replacing all drives at once risks data loss, while changing the RAID level does not directly address the need to increase capacity in an existing RAID 6 configuration.
