CompTIA A+ Core 1 (220-1001) — Question 180

A technician needs to configure a high-end workstation with four hard drives for redundancy. The customer wants the end result to have the highest capacity possible but still have the ability to survive a drive failure. Which of the following RAID levels should the technician configure to accomplish this?

Answer options

• A. RAID 0
• B. RAID 1
• C. RAID 5
• D. RAID 10

Correct answer: C

Explanation

RAID 5 provides a balance of high capacity and redundancy, utilizing striping with parity across the drives. This means it can tolerate the failure of one drive while still maintaining data integrity and maximizing storage use. RAID 0 offers no redundancy, RAID 1 sacrifices half the capacity for mirroring, and RAID 10 requires a minimum of four drives but does not provide the same capacity efficiency as RAID 5.
