The correct answer is C. RAID 10. RAID 10 combines mirroring and striping across drive pairs, offering the highest fault tolerance among common RAID levels by tolerating multiple simultaneous drive failures.

Why each option

RAID 10 combines mirroring and striping across drive pairs, offering the highest fault tolerance among common RAID levels by tolerating multiple simultaneous drive failures.

ARAID 3

RAID 3 uses byte-level striping with a single dedicated parity disk and can only tolerate the failure of one drive, making it far less fault-tolerant than RAID 10.

BRAID 5

RAID 5 distributes parity across all drives but can only tolerate a single drive failure; a second concurrent failure before rebuild completes results in data loss.

CRAID 10Correct

RAID 10 (also called RAID 1+0) mirrors drives into pairs first, then stripes across those pairs. With six drives, three mirror pairs are created, and the array can survive the loss of one drive per pair - potentially three simultaneous failures - without data loss. This makes RAID 10 the configuration offering maximum fault tolerance when multiple drives are available.

DRAID 0

RAID 0 uses only striping with no redundancy or parity and provides zero fault tolerance - any single drive failure causes complete data loss.
