Show answer & explanation
Correct answer: A
Correct matching: RAID Level 2 → Also known as Memory style error correcting code organization; RAID Level 3 → Bit interleaved parity; RAID Level 5 → Block interleaved distribution parity; RAID Level 6 → Also known as P+Q redundancy Scheme.
RAID Level 2 → Also known as memory-style error-correcting code organization. Uses error-correcting codes (like Hamming) and bit-level striping; designed similarly to memory ECC.
RAID Level 3 → Bit interleaved parity. Data is striped at the byte/bit level across disks with a dedicated parity disk providing parity for the interleaved bits.
RAID Level 5 → Block interleaved distribution parity. Data is striped at the block level and parity is distributed across all disks (rotating parity), improving performance and redundancy.
RAID Level 6 → Also known as P+Q redundancy scheme. Provides dual parity (two independent parity calculations, often called P and Q) allowing recovery from two simultaneous disk failures.
