Data is striped at a byte level across multiple drives and parity information is distributed among all member drives. What RAID level is represented here?

The correct answer is D. RAID Level 5. RAID 5 is the level characterized by distributed parity - parity information is spread across all member drives rather than stored on a single dedicated parity disk. This is its defining feature and key differentiator. For context: RAID 0 (A) uses striping with no parity; RAID…

Explanation

RAID 5 is the level characterized by distributed parity - parity information is spread across all member drives rather than stored on a single dedicated parity disk. This is its defining feature and key differentiator. For context: RAID 0 (A) uses striping with no parity; RAID 1 (B) uses mirroring; RAID 3 (C) uses byte-level striping but with a single dedicated parity drive (not distributed). The question's emphasis on 'parity distributed among all member drives' is the hallmark of RAID 5. Note: technically RAID 5 uses block-level striping, but the distributed parity characteristic is the definitive identifier tested here.
