- D.
RAID 6
Correct Answer
A. RAID 0Explanation
Windows refers to RAID 0 as a striped volume. In RAID 0, data is divided into blocks and distributed across multiple disks. This allows for improved performance as data can be read and written simultaneously from multiple disks. However, RAID 0 does not provide any fault tolerance or data redundancy, meaning that if one disk fails, all data is lost.Rate this question:
