CompTIA Linux+ (XK0-005) — Question 307

Which of the following options represents disk mirroring?

Answer options

• A. RAID 0
• B. RAID 1
• C. RAID 5
• D. RAID 6

Correct answer: B

Explanation

RAID 1 is the correct answer because it involves creating an exact copy of data on two or more disks, which is the essence of disk mirroring. In contrast, RAID 0 focuses on data striping without redundancy, while RAID 5 and RAID 6 incorporate parity for fault tolerance rather than mirroring.
