Dell Technologies Proven Professional – Midrange Storage Solutions — Question 50

A customer must provision file systems on a Dell Unity XT 480F for a test environment. A dynamic pool will be configured with RAID 5 (4+1) protection to match the production pool. The used tier contains only SAS Flash 3 drives.

What is the minimum drive count necessary to create this pool?

Answer options

• A. 10
• B. 11
• C. 6
• D. 5

Correct answer: A

Explanation

To implement a RAID 5 (4+1) configuration, you need a minimum of 5 drives, where 4 are used for data and 1 for parity. However, in this scenario, additional drives are necessary to meet the requirements of the dynamic pool, resulting in a total of 10 drives being needed. The other options (11, 6, and 5) either exceed the minimum requirement or do not meet it for the intended setup.
