CompTIA Server+ (SK0-005) — Question 259

An administrator has been asked to deploy a database server that provides the highest performance with fault tolerance. Which of the following RAID levels will fulfill this request?

Answer options

• A. RAID 0
• B. RAID 1
• C. RAID 5
• D. RAID 6
• E. RAID 10

Correct answer: E

Explanation

RAID 10 combines the benefits of both RAID 0 and RAID 1, providing high performance through striping and fault tolerance through mirroring. RAID 0 offers no redundancy, making it unsuitable for fault tolerance, while RAID 1, RAID 5, and RAID 6 do not deliver the same level of performance as RAID 10 due to their write penalty or lack of striping.
