CompTIA A+ Core 1 (220-1001) — Question 187

A technician is installing and configuring a storage array on a Windows server. There are four disk slots available, and the only requirement is that the RAID array survives the loss of two drives. Which of the following RAID levels should be used?

Answer options

• A. 1
• B. 5
• C. 10
• D. 60

Correct answer: D

Explanation

RAID 60 is designed to provide fault tolerance by combining RAID 6 and striping, allowing it to survive the loss of two drives within each RAID 6 set, which is suitable for the given requirement. RAID 1 and RAID 5 cannot survive the loss of two drives, while RAID 10 requires a minimum of four drives but only protects against one drive failure in each mirrored pair.
