Question: 1 / 525

Which RAID level is characterized by mirroring?

RAID 0

RAID 1

RAID 1 is the correct answer because it is the only level that utilizes mirroring as its primary feature. RAID 0, also known as striping, distributes data across multiple disks for increased performance but does not involve mirroring. RAID 5, also known as striping with parity, distributes data and parity information across multiple disks for increased performance and fault tolerance, but again does not involve mirroring. RAID 10 is a combination of striping and mirroring, but it is not the only level that utilizes mirroring as its primary feature. Therefore, RAID 1 is the best option as it is the only RAID level that is characterized by mirroring.
