Dell EMC Associate – Information Storage and Management v4 — Question 22

What is the primary advantage of RAID 6 compared to RAID 5?

Answer options

• A. High available storage capacity
• B. Low write penalty
• C. High resiliency
• D. Low rebuild time for data

Correct answer: A

Explanation

The primary advantage of RAID 6 over RAID 5 is its ability to provide high resiliency through dual parity, allowing it to withstand two simultaneous drive failures. While RAID 5 also offers storage efficiency, RAID 6's additional parity means it can maintain data integrity better than RAID 5. Options B and D do not accurately reflect RAID 6's strengths compared to RAID 5.
