The question asks about the next step to perform network troubleshooting after identifying an issue, which is the first step in the CompTIA Network+ troubleshooting methodology12.

The second step is to establish a theory of probable cause, which involves analyzing the symptoms, researching the knowledge base, and identifying the most likely reasons for the issue12.

The other options are not the correct next step, as they occur later in the troubleshooting process:

Implementing a solution is the fourth step, after testing the theory and determining the next steps12.

Escalating the issue is a possible action in the third step, if the theory is not confirmed or the problem is beyond the scope of authority or ability12.

Documenting the findings is the final step, after verifying the functionality and implementing preventive measures12. References:
