Show answer & explanation
Correct answer: B
Correct matching and explanation:
RAID Level 1 — disk mirroring. Data is duplicated across disks for redundancy.
RAID Level 2 — ECC organization. Uses bit-level striping with error-correcting codes (Hamming) for fault detection and correction.
RAID Level 3 — bit-interleaved parity organization. Uses byte/bit-level striping with a dedicated parity disk to provide parity for each small unit.
RAID Level 4 — block-interleaved parity organization. Uses block-level striping with a dedicated parity disk (parity for whole blocks rather than for individual bytes/bits).
