CompTIA Server+ (SK0-005) — Question 51

A technician recently upgraded several pieces of firmware on a server. Ever since the technician rebooted the server, it no longer communicates with the network.
Which of the following should the technician do FIRST to return the server to service as soon as possible?

Answer options

• A. Replace the NIC
• B. Make sure the NIC is on the HCL
• C. Reseat the NIC
• D. Downgrade the NIC firmware

Correct answer: D

Explanation

The correct action is to downgrade the NIC firmware because the upgrade may have caused compatibility issues preventing network communication. Replacing or reseating the NIC are unnecessary steps if the issue is firmware-related, and checking the HCL is not a priority when a firmware rollback could resolve the problem immediately.
