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
- A. 750 GB
- B. 1000 GB
- C. 500 GB
- D. 250 GB
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.
