Explanation

The CompTIA network troubleshooting methodology follows this order: (1) Identify the problem, (2) Establish a theory of probable cause, (3) Test the theory, (4) Establish a plan of action, (5) Implement the solution, (6) Verify functionality, (7) Document findings. In this scenario, the user has already provided the root cause - a cut cable. This means steps 1 through 3 are effectively complete: the problem is identified, the cause is known (cut cable), and no further testing is needed to confirm it. Therefore, the NEXT logical step is to establish a plan of action (step 4), which means determining how to fix or replace the damaged cable. Choices A and B are already done, and D (establish a theory) is also already resolved since the cause is confirmed.
