CompTIA Security+ (SY0-601) — Question 482

A security administrator needs to create a RAID configuration that is focused on high read speeds and fault tolerance. It is unlikely that multiple drives will fail simultaneously. Which of the following RAID configurations should the administrator use?

Answer options

• A. RAID 0
• B. RAID 1
• C. RAID 5
• D. RAID 10

Correct answer: D

Explanation

RAID 10 combines the benefits of both RAID 1 and RAID 0, offering high read speeds and fault tolerance through mirroring and striping. RAID 0 provides no redundancy, RAID 1 lacks the same level of performance, and RAID 5 requires a minimum of three drives, which may not be as fast as RAID 10 in read operations.
