CompTIA Network+ (N10-009)Network TroubleshootingEasy
A network technician is following the standard troubleshooting methodology after a user reports intermittent connectivity. The technician has already identified the problem and established a theory of probable cause. What should the technician do NEXT?
- AEstablish a plan of action to resolve the problem
- BImplement the solution or escalate as necessary
- CDocument findings, actions, and outcomes
- DTest the theory to determine the cause
Show answer & explanationAnswer & explanation
Correct answer: D. Test the theory to determine the cause
The CompTIA troubleshooting methodology follows: identify the problem, establish a theory, test the theory, establish a plan of action, implement the solution, verify functionality, and document. Since the theory has already been established, the next step is to test it.
Why the other options are wrong
- A. Planning the action happens only after the theory is confirmed.
- B. Implementation comes after a plan of action is created.
- C. Documentation is the final step, not the next one.
Troubleshooting Methodology Order
The structured sequence CompTIA defines for resolving network problems, ensuring consistent and efficient issue resolution.
- Order: Identify problem, establish theory, test theory, plan of action, implement, verify, document
- Testing the theory confirms or rules out the suspected cause before acting
- Documentation always occurs last regardless of outcome
