EMC Proven Professional – PowerMax Specialist — Question 54

A company needs to expand their dynamic pool by 5 TB. The current dynamic pool consists of sixty-three 3.8 TB SSD that are configured for RAID5 4+1.
What is the minimum number of drives needed for the pool expansion?

Answer options

• A. 1
• B. 6
• C. 7
• D. 8

Correct answer: A

Explanation

The correct answer is A because adding one additional 3.8 TB drive will provide enough space to meet the 5 TB expansion requirement. The other options suggest adding more drives than necessary, which would exceed the needed capacity for the expansion.
