CompTIA Server+ (SK0-005) — Question 255

A technician is configuring a new server with four disks for the development team. The requirements are disk redundancy and maximum usable disk capacity. Which of the following RAID levels should be used for this server?

Answer options

• A. 0
• B. 1
• C. 5
• D. 10

Correct answer: C

Explanation

RAID 5 provides both redundancy and efficient use of disk space by using parity information, allowing for one disk failure without data loss. RAID 0 offers no redundancy, RAID 1 requires double the disk space for mirroring, and RAID 10 combines RAID 1 and 0, which reduces capacity too much for this scenario.
