After upgrading several firmware components on a server, it no longer communicates with the network. What should the technician do first to resolve this issue?

• A. Reset the network configuration
• B. Reinstall the operating system
• C. Downgrade the NIC firmware
• D. Check network cables

Answer: (C)

In this scenario, downgrading the Network Interface Card (NIC) firmware is the most logical first step to resolving network communication issues following a firmware upgrade. Firmware updates can sometimes introduce compatibility issues or bugs that prevent proper functionality. By reverting the NIC firmware to a previous version, the technician may restore the network connectivity that was lost after the upgrade. Network issues can often stem from mismatched firmware versions, and downgrading allows the technician to determine if the most recent firmware caused the problem. If connectivity is restored after the downgrade, the technician can then decide whether to reattempt the upgrade with a different version or await a fix from the vendor. While checking network cables, resetting network configurations, or reinstalling the operating system could also be valid troubleshooting steps, starting with the NIC firmware downgrade directly addresses the possible root cause related to the changes made during the firmware upgrade. This focused approach can be more efficient than checking other hardware or software components first.
