Which sequence represents the correct order of the general network troubleshooting methodology?

• A. Gather symptoms; establish a theory; test the theory; implement a fix; verify full functionality; document the results.
• B. Gather symptoms; test the theory; establish a theory; implement a fix; verify full functionality; document the results.
• C. Establish a theory; gather symptoms; test the theory; implement a fix; verify full functionality; document the results.
• D. Gather symptoms; establish a theory; implement a fix; test the theory; verify full functionality; document the results.

Answer: (A)

The main idea being tested is a logical, evidence-based problem-solving flow used in IT troubleshooting. Start by collecting information about what’s happening—gather the symptoms—to understand the scope of the issue. Then form a hypothesis about the probable cause based on what you observed. Next, test that hypothesis to confirm whether it explains the problem. Once you’ve validated the cause, implement the fix and then verify that the issue is resolved and that full functionality has returned. Finally, document what was found and what was done for future reference and learning. This order matters because you avoid guessing without evidence, you prevent implementing the wrong fix, and you capture the results for future problems. The other sequences disrupt this flow by testing before forming a theory, starting with theory before symptoms, or applying a fix before testing.
