Dell EMC Specialist – Systems Administrator, Unity XT — Question 77

A customer has a Dell EMC Unity 680F array with a single pool consisting of 10 drives configured with RAID 5 (4+1). What is the minimum number of drives required to expand the pool?

Answer options

• A. 1
• B. 5
• C. 6
• D. 7

Correct answer: A

Explanation

To expand a RAID 5 (4+1) configuration, you only need to add one additional drive to create space for more data and maintain the RAID level's redundancy. Other options like 5, 6, or 7 drives are unnecessary and would exceed the minimum requirement for expansion.
