CompTIA A+ Core 1 (220-1001) — Question 8

A technician is talking to end users about the specifications for an upgraded application server. The users of the application report that there cannot be any unscheduled downtime or data loss. Additionally, they would like the performance of the application to improve over the previous server in any way possible. The previous server was running RAID 5.
Which of the following RAID solutions should be implemented in this scenario?

Answer options

Correct answer: D

Explanation

RAID 10 combines the benefits of both mirroring and striping, providing excellent performance and redundancy, which satisfies both the requirement for improved performance and the need for no data loss. RAID 0 offers no redundancy, making it unsuitable for preventing data loss, while RAID 1 and RAID 6 do not provide the same level of performance as RAID 10 when it comes to write operations.
