CompTIA Linux+ (XK0-004) — Question 139

A four-drive Linux NAS has been improperly configured. Each drive has a capacity of 6TB, for a total storage capacity of 24TB. To reconfigure this unit to be not pluggable for drive replacement and provide total storage of 11TB to 12TB, which of the following would be the correct RAID configuration?

Answer options

• A. RAID 01
• B. RAID 03
• C. RAID 10
• D. RAID 50

Correct answer: C

Explanation

RAID 10 is the correct configuration as it provides redundancy and efficient use of storage, resulting in a total usable capacity of 12TB with four 6TB drives. RAID 01 and RAID 03 do not achieve the desired capacity while RAID 50 would exceed the specified range, making them unsuitable options.
