Dell EMC Specialist – Implementation Engineer, PowerEdge Server — Question 13

A storage administrator is provisioning storage on a PowerMax 2000 array. The application requires fast reads and the highest possible data protection.
Which RAID level should be recommended?

Answer options

• A. RAID 6 (6 + 2)
• B. RAID 5 (3 + 1)
• C. RAID 6 (14 + 2)
• D. RAID 5 (7 + 1)

Correct answer: B

Explanation

RAID 5 (3 + 1) is ideal for scenarios requiring fast read performance and a good balance of data protection, as it allows for one disk failure without data loss. RAID 6 configurations, while offering higher fault tolerance, can result in slower read speeds due to additional parity calculations. Therefore, RAID 5 (3 + 1) is the most suitable option for the given requirements.
