A technician is working on a server that is experiencing network connectivity issues. The technician replaces the NIC on the server, but this does not resolve the issue. Which of the following…

The CompTIA troubleshooting methodology specifies that if a solution does not resolve the problem, the technician must re-establish a new theory of probable cause. The failed NIC replacement rules out the NIC as the root cause, so a new hypothesis - such as a faulty switch port, cable, or driver - must be formed before any further action is taken.

Root cause analysis is conducted after the issue is fully resolved, not while the problem remains active and unfixed.

Documenting findings is the final step performed only after resolution is confirmed, not when a fix attempt has failed.

Identifying additional changes is not a defined step in the troubleshooting methodology and does not follow the structured process of re-establishing a theory.
