CompTIA Server+ (SK0-005) — Question 72

An administrator is investigating a physical server that will not boot into the OS. The server has three hard drives configured in a RAID 5 array. The server passes
POST, but the OS does not load. The administrator verifies the CPU and RAM are both seated correctly and checks the dual power supplies. The administrator then verifies all the BIOS settings are correct and connects a bootable USB drive in the server, and the OS loads correctly. Which of the following is causing the issue?

Answer options

• A. The page file is too small.
• B. The CPU has failed.
• C. There are multiple failed hard drives.
• D. There are mismatched RAM modules.
• E. RAID 5 requires four drives.

Correct answer: C

Explanation

The issue is caused by multiple failed hard drives in the RAID 5 array, which requires at least one functioning drive to operate properly. The other options, such as a small page file or mismatched RAM, do not affect the ability to boot from the RAID configuration itself. Additionally, RAID 5 can function with three drives, making option E incorrect.
