A technician troubleshooting a mail server determines that the server is low on available hard drive space and needs an additional hard drive installed. The server will need to be offline for the…

After identifying both the problem (low disk space) and the required solution (add a hard drive), the troubleshooting methodology requires establishing a plan of action before implementation, which includes notifying stakeholders of the upcoming outage. Taking the mail server offline will directly disrupt users who depend on it, so communication must happen before the change is made. This step ensures organizational awareness and is a core requirement of structured change management.

Implementing one change at a time is a best practice that applies during the implementation phase, which comes after users have already been notified of the planned maintenance.

Collecting additional information is an earlier step in the troubleshooting methodology - the technician has already identified the problem and the corrective action needed.

Documenting findings, actions, and outcomes is the final step of the troubleshooting methodology and occurs only after the solution has been implemented and verified as successful.
