CompTIA A+ Core 1 (220-1101) — Question 555

A technician receives several error alerts on a server after an unexpected reboot. A message states that one or more disks are in a degraded state. When the technician advances to the next error message, it indicates the OS is missing. Which of the following are the MOST likely causes of these errors? (Choose two.)

Answer options

• A. Missing drives in the OS
• B. RAID failure
• C. Bootable device not found
• D. Data loss
• E. Controller failure
• F. CMOS corruption
• G. TPM malfunction

Correct answer: B, C

Explanation

The correct answers B (RAID failure) and C (Bootable device not found) are likely causes because a degraded disk state often leads to RAID issues, and if the RAID is compromised, the system may not find a bootable device. The other options, while they may relate to disk or system issues, do not directly explain the specific error messages about degraded disks and an absent OS.
