CompTIA Server+ (SK0-005) — Question 122

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 turn on. There are two arrays on the failed server: a two-drive RAID 0 set for the OS, and an eight-drive RAID 10 set for data.

Which of the following failure scenarios MOST likely occurred?

Answer options

• A. A drive failed in the OS array.
• B. A drive failed and then recovered in the data array.
• C. A drive failed in both of the arrays.
• D. A drive failed in the data array.

Correct answer: A

Explanation

The correct answer is A because the RAID 0 array for the OS requires both drives to function; if one fails, the entire array becomes unusable, leading to a server crash. Options B and D are less likely because they do not explain the total server failure, and option C is not possible since only one drive failure in the OS array is sufficient to cause the crash.
