Dell EMC Associate – Information Storage and Management v5 — Question 97

What is the total usable data storage capacity in this scenario:

- a RAID 6 array with four 250 GB disks

Answer options

Correct answer: C

Explanation

In a RAID 6 configuration, two disks are used for parity, which means the usable capacity is calculated as (Number of disks - 2) * Size of each disk. With four 250 GB disks, the calculation is (4 - 2) * 250 GB = 500 GB, making option C the correct answer. Options A, B, and D do not account for the parity disks correctly, leading to incorrect total capacities.
