After successfully testing a probable cause to an issue, which of the following is the NEXT troubleshooting step?

Implementing the solution or escalating happens after a plan of action has been established and approved, not immediately after testing a probable cause.

Performing a root cause analysis is often done after the problem is resolved to prevent recurrence, not as the immediate next step after testing a probable cause.

After successfully identifying and testing a probable cause, the next logical step in a structured troubleshooting process is to establish a plan of action to resolve the problem. This plan outlines the steps needed to apply the solution and mitigate risks.

Verifying full system functionality and implementing preventative measures are steps performed after the solution has been implemented, not before.
