Question
A systems administrator is investigating a server with a RAID array that will not boot into the OS. The administrator notices all the hard drives are reporting to be offline. The administrator checks the RAID controller and verifies the configuration is correct. The administrator then replaces one of the drives with a known-good drive, but it appears to be unavailable as well. Next, the administrator takes a drive out of the server and places it in a spare server, and the drive is available and functional. Which of the following is MOST likely causing the issue?
Options
- AThe kernel is corrupt.
- BResources are misallocated.
- CThe backplane has failed.
- DThe drives need to be reseated.

Explanation
The backplane is a circuit board that connects multiple hard drives to a RAID controller and provides power and data transfer between them. If the backplane has failed, it may cause all the hard drives to be offline and prevent the server from booting into the OS. The fact that replacing one of the drives with a known-good drive did not work, and that taking a drive out of the server and placing it in a spare server made it functional, suggests that the problem is not with the drives themselves but with the backplane. A corrupt kernel (A) would not affect the status of the hard drives, as it is a software component of the OS. Resource misallocation (B) would not cause all the hard drives to be offline, as it is a configuration issue that affects how resources are assigned to processes or applications. Reseating the drives (D) would not help, as it would not fix a faulty
