An administrator needs to install two hard drives in a server and configure the system for maximum redundancy. Which of the following RAID levels would be BEST suited for the administrator?

RAID 0 stripes data across drives to improve performance but provides zero redundancy - losing either drive results in total data loss.

RAID 1 writes identical data to two drives simultaneously so that if one drive fails, the other continues to serve data without any interruption or data loss. It requires a minimum of exactly two drives, making it perfectly suited for a two-drive configuration focused on maximum redundancy. RAID 5 and RAID 10 require three and four drives respectively, disqualifying them from this scenario.

RAID 5 uses distributed parity across drives and requires a minimum of three drives, so it cannot be configured with only two drives.

RAID 10 combines striping and mirroring and requires a minimum of four drives, making it impossible to implement with only two drives.
