Which of the following RAID configurations has a single point of failure?

The correct answer is A. 0. RAID 0 uses striping to split data across two or more drives for performance gains, but provides no redundancy whatsoever. If any single drive in a RAID 0 array fails, all data across the entire array is lost - making every drive a single point of failure. RAID 1 (mirroring)…

Explanation

RAID 0 uses striping to split data across two or more drives for performance gains, but provides no redundancy whatsoever. If any single drive in a RAID 0 array fails, all data across the entire array is lost - making every drive a single point of failure. RAID 1 (mirroring) can survive a drive failure. RAID 5 (striping with parity) can survive one drive failure. RAID 10 (mirror + stripe) can survive multiple drive failures as long as no two failed drives are in the same mirrored pair. RAID 0 is the only configuration here with no fault tolerance.
