A high-end workstation is operating as expected, but two of the four SATA drives are displaying solid fault lights. Which of the following is the MOST likely reason for this issue?

The correct answer is B. The RAID level of the disk array is 10. RAID 10 (also known as RAID 1+0) is a combination of RAID 1 (mirroring) and RAID 0 (striping). In a RAID 10 configuration, data is mirrored across multiple pairs of drives, and then those mirrored pairs are striped for performance. If two drives in one of the mirrored pairs fail,

Explanation

RAID 10 (also known as RAID 1+0) is a combination of RAID 1 (mirroring) and RAID 0 (striping). In a RAID 10 configuration, data is mirrored across multiple pairs of drives, and then those mirrored pairs are striped for performance. If two drives in one of the mirrored pairs fail, it can result in a fault condition for the RAID array, causing the fault lights to indicate the issue. So, if the workstation is using RAID 10 and two drives in one of the mirrored pairs have failed, it would explain the solid fault lights on those drives.
