The correct answer is A. A drive failed in the OS array. If a server has two arrays on the failed server: a two-drive RAID 0 set for the OS, and an eight- drive RAID 10 set for data, then the most likely failure scenario that caused the server to crash and not boot is that a drive failed in the OS array.

Question
An administrator is troubleshooting a RAID issue in a failed server. The server reported a drive failure, and then it crashed and would no longer boot. There are two arrays on the failed server: a two-drive RAIO 0 set tor the OS, and an eight-drive RAID 10 set for data. Which of the following failure scenarios MOST likely occurred?
Options
- AA drive failed in the OS array.
- BA drive failed and then recovered in the data array.
- CA drive failed in both of the arrays.
- DA drive failed in the data array.

Explanation
If a server has two arrays on the failed server: a two-drive RAID 0 set for the OS, and an eight- drive RAID 10 set for data, then the most likely failure scenario that caused the server to crash and not boot is that a drive failed in the OS array. RAID 0 is a RAID configuration that stripes data across two or more drives without parity or redundancy. RAID 0 offers high performance but no fault tolerance. If one drive fails in RAID 0, all data is lost and the system cannot boot. RAID 10 is a RAID configuration that combines disk mirroring and disk striping with parity. RAID 10 offers high performance and fault tolerance. RAID 10 can tolerate up to one drive failure per mirrored pair without losing data or functionality.
