CompTIA Cloud+ (CV0-003) — Question 261

A systems administrator is deploying a new storage array for backups. The array provides 1PB of raw disk space and uses 14TB nearline SAS drives. The solution must tolerate at least two failed drives in a single RAID set. Which of the following RAID levels satisfies this requirement?

Answer options

Correct answer: D

Explanation

RAID 6 is the correct choice because it can tolerate the failure of two drives in a single RAID set, providing enhanced redundancy. In contrast, RAID 0 offers no fault tolerance, RAID 1 allows for only one drive failure, RAID 5 can only handle a single drive failure, and RAID 10, while fault-tolerant, would not meet the requirement of supporting two failed drives as effectively as RAID 6.
