Which of the following troubleshooting methods is performed after resolving an issue?

The method of documenting findings is a crucial step performed after resolving an issue because it ensures that all actions taken, observations made, and solutions applied are recorded for future reference. This process not only helps in creating a knowledge base that can be useful for similar issues in the future but also aids in identifying patterns that can lead to proactive measures in preventing the same problem from occurring again.

Documentation provides clarity and can be essential for team collaboration, where other technicians may need to understand the previous actions taken on a system. It also serves as a crucial part of compliance and auditing processes in many organizations, ensuring that there is a formal record of what was done, how it was resolved, and any follow-up actions that may be necessary.

In contrast, verifying system connectivity, implementing the solution, and establishing a theory are all steps taken during the troubleshooting process itself, rather than after the issue has been resolved. Each of these activities plays an important role in diagnosing and fixing problems but does not fulfill the purpose of documenting the resolution for future reference.
