Dell Technologies Proven Professional – Midrange Storage Solutions — Question 7

A systems administrator has deployed a Dell Unity XT 380F system with 15x 1.92 TB SSD drives, in a RAID 5 dynamic pool. Shortly after deployment, the administrator wants to expand the capacity of the system and use larger drives to increase the density.
What will happen if the administrator adds 4x 3.84 TB SSD drives?

Answer options

• A. The mixing of drive types is not supported, and the operation will fail.
• B. Only half of the capacity of the new drives will be available.
• C. Three of the drives will be added with a fourth reserved as spare.
• D. The full capacity of the drives will be available.

Correct answer: B

Explanation

The correct answer is B because in a RAID configuration, if larger drives are added to a pool with smaller drives, only the capacity equivalent to the smaller drives will be utilized. Options A and C are incorrect as the mixing of drive types is allowed and all drives can be added, while option D is wrong because the full capacity of the new drives cannot be used due to the existing smaller drives.
