Explanation:
Disk striping is the process of writing bits of data across multiple disks.
Incorrect Answers:
B: Disk mirroring is the process of writing the same data to two disks so that the two disks contain identical copies of the data.
C: Parity is required to rebuild data on a failed disk. It is required with striping to provide fault tolerance.
