CompTIA Server+ (SK0-005) — Question 125

A server administrator wants to ensure a storage array can survive the failure of two drives without the loss of data. Which of the following RAID levels should the administrator choose?

Answer options

• A. 0
• B. 1
• C. 5
• D. 6

Correct answer: D

Explanation

RAID 6 is the correct choice because it can tolerate the failure of two drives by using dual parity, ensuring data integrity. RAID 0 offers no redundancy, RAID 1 only protects against one drive failure, and RAID 5 can only handle a single drive failure due to its single parity configuration.
