CompTIA Server+ SK0-005 Practice Question

Because the single change you implemented did not fix the problem and introduced new symptoms, the methodology dictates rolling the system back to its last known-good state before trying something else. Restoring the previous NIC driver removes the ineffective change, returns the server to a stable baseline, and lets you test a different fix one step at a time. Installing additional updates, replacing hardware, or escalating without first reversing the failed change would create multiple variables or leave an unverified configuration in place, making root-cause analysis harder and risking further outages.
