A technician has a computer with three hard drives and wants to create a RAID array with parity. Which of the following RAID configurations should be installed?

The correct answer is C. RAID 5. RAID 5 uses block-level striping with distributed parity, requiring a minimum of 3 drives. Parity data is spread across all drives, allowing the array to survive a single drive failure with no data loss. RAID 0 (A) uses striping only - no redundancy or parity, and increases…

Explanation

RAID 5 uses block-level striping with distributed parity, requiring a minimum of 3 drives. Parity data is spread across all drives, allowing the array to survive a single drive failure with no data loss. RAID 0 (A) uses striping only - no redundancy or parity, and increases failure risk. RAID 1 (B) is mirroring (requires 2 drives, no parity). RAID 10 (D) combines mirroring and striping but requires a minimum of 4 drives. With exactly 3 drives and a requirement for parity, RAID 5 is the only correct option.
