CompTIA A+ Core 1 (220-1101) — Question 63

A drive failed on a server that was leveraging a RAID disk configuration. The server administrator would like to rebuild the array so it can withstand a potential multidrive failure in the future. Which of the following RAID configurations will the administrator MOST likely select?

Answer options

Correct answer: D

Explanation

RAID 10 is the most suitable choice because it combines the mirroring of RAID 1 and the striping of RAID 0, providing both redundancy and improved performance, thus allowing for multiple drive failures. In contrast, RAID 0 offers no redundancy, RAID 1 only protects against a single drive failure, and RAID 5 can only withstand a single drive failure, making them less suitable for this scenario.
