Certified Network Defender (CND) — Question 181

Which of the following types of RAID offers no protection for the parity disk?

Answer options

• A. RAID 2
• B. RAID 1
• C. RAID 5
• D. RAID 3

Correct answer: D

Explanation

RAID 3 uses byte-level striping with a dedicated parity disk, meaning it does not offer redundancy for the parity itself. In contrast, RAID 1 provides mirroring, RAID 5 distributes parity across all disks, and RAID 2 uses Hamming code for error correction, all of which involve some level of protection for data integrity.
