Certified Information Systems Security Professional (CISSP) — Question 318

What level of Redundant Array of Independent Disks (RAID) is configured PRIMARILY for high-performance data reads and writes?

Answer options

• A. RAID-0
• B. RAID-1
• C. RAID-5
• D. RAID-6

Correct answer: A

Explanation

RAID-0 is configured primarily for high-performance data reads and writes as it stripes data across multiple disks, which increases throughput. RAID-1, RAID-5, and RAID-6 prioritize redundancy and fault tolerance over performance, which can lead to slower read and write speeds compared to RAID-0.
