Question

Which of the following is the characteristic of RAID-5?

• A. Dedicated Parity
• B. Distributed Parity
• C. Double Parity
• D. Single Parity

Hint:

RAID-5 improves data protection by distributing parity across all drives, ensuring fault tolerance in case of a single disk failure.

Answer 1

The Correct Option is B

Step 1: Understanding RAID-5 Characteristics
RAID-5 (Redundant Array of Independent Disks - Level 5) is a widely used RAID configuration that provides both redundancy and improved performance.
Step 2: Evaluating the Options
- (A) Incorrect: RAID-5 does not use dedicated parity; dedicated parity is used in RAID-4.
- (B) Correct: RAID-5 uses distributed parity, meaning that parity information is spread across all disks instead of being stored on a single dedicated disk.
- (C) Incorrect: Double parity is used in RAID-6, not RAID-5.
- (D) Incorrect: Single parity is a general term and does not specifically refer to RAID-5.
