CompTIA Server+ SK0-005 Practice Question
During an investigation into repeated network-adapter failures on a production file server, a systems administrator confirms that a newly released NIC driver from the hardware vendor should resolve the issue. The update has been approved by the change-advisory process and a 20-minute maintenance window has been scheduled. According to the CompTIA troubleshooting methodology, which action should the administrator take immediately before installing the driver?
Disable the Windows Update service to prevent concurrent patch installs.
Increase the virtual NIC receive buffer size and record the new baseline.
Create and verify a full system backup or VM snapshot of the server.
Clear the system and application event logs to make post-change errors easier to spot.
