CompTIA Server+ (SK0-005) — Question 244

A technician needs to replace two RAID controllers on a database server as part of an upgrade. The server has six external storage arrays and eight internal disks that are controlled by the two RAID controllers. The technician completes the replacement and powers the systems back on, but the server OS detects several missing disks in the configuration. Which of the following steps should the technician take first to resolve this issue?

Answer options

• A. Reboot to the RAID controller BIOS and rescan for attached disks and arrays.
• B. Start the motherboard UEFI and confirm the RAID controller start order is correct.
• C. Turn off the external arrays and reboot the server to redetect the internal disks first.
• D. Turn off all components and confirm all external and internal cables before rebooting.

Correct answer: D

Explanation

The correct answer is D because verifying all cable connections ensures that there are no loose or improperly connected cables, which could be the cause of the missing disks. The other options involve actions that may not resolve underlying hardware connection issues before confirming that the physical setup is correct.
