CompTIA Security+ (SY0-601) — Question 398

A critical file server is being upgraded, and the systems administrator must determine which RAID level the new server will need to achieve parity and handle two simultaneous disk failures. Which of the following RAID levels meets this requirement?

Answer options

• A. RAID 0+1
• B. RAID 2
• C. RAID 5
• D. RAID 6

Correct answer: D

Explanation

RAID 6 is the correct answer because it provides dual parity, allowing it to withstand two simultaneous disk failures. RAID 0+1 offers redundancy but only supports one disk failure, RAID 2 is not commonly used and does not provide parity, and RAID 5 can only handle one disk failure at a time.
