A systems administrator successfully resolved an issue with a critical file server that was experiencing slow I/O performance. After thorough testing, the administrator confirmed that correcting a misconfigured RAID controller setting resolved the problem and performance returned to normal. According to the CompTIA troubleshooting methodology, which of the following actions BEST represents the final step of this process?
Create a detailed record of the incident, including symptoms, diagnostic steps, root cause, and the resolution implemented.
Perform a new full backup of the file server to capture the stable configuration.
Escalate the issue to the storage vendor to report the potential for misconfiguration.
Notify impacted stakeholders that the server performance issue has been resolved.
The correct answer is to create a detailed record of the incident. The CompTIA troubleshooting methodology is a structured process, and the final step is to document the findings, actions, and outcomes. This documentation is critical for future reference, knowledge sharing among team members, and building a knowledge base that can speed up the resolution of similar issues in the future. Notifying users is an important communication step that occurs after verifying the solution but before the final documentation. Performing a backup is part of verifying system functionality or a preventative measure, which should have been done before making changes and is not the final documentation step. Escalating to the vendor is a potential follow-up action derived from the root cause analysis, but the primary concluding step of the troubleshooting process itself is documentation.
