What do you call an extra drive usually found with RAID that can be used when a drive fails?

The correct answer is B. Hot Spare. A hot spare is much like it sounds. When drives need to be fault tolerant, you can combine a hot spare drive with a RAID. Then, if a drive fails, the system will automatically grab the hot spare drive to replace the failed drive and rebuild or restore the missing data.
