Zorluk: KolayCompTIA Troubleshooting Methodology

A network technician needs to troubleshoot a reported network outage by following standard industry methodology. Place the given CompTIA troubleshooting methodology steps in the correct sequential order from first step to last step.

  1. 1Identify the problem by gathering information, questioning users, and determining if anything has changed.
  2. 2Establish a theory of probable cause, questioning the obvious and considering OSI layer approaches.
  3. 3Test the theory to determine the exact cause of the failure.
  4. 4Establish a plan of action to resolve the problem and implement the solution.
  5. 5Verify full system functionality and, if applicable, implement preventive measures.

Cevap

The correct sequential order is: 1) Identify the problem, 2) Establish a theory of probable cause, 3) Test the theory to determine cause, 4) Establish a plan of action and implement the solution, and 5) Verify full system functionality and implement preventive measures.
The official CompTIA 6-step troubleshooting methodology follows a strict sequence: 1. Identify the problem, 2. Establish a theory of probable cause, 3. Test the theory to determine cause, 4. Establish a plan of action to resolve the problem and implement the solution, 5. Verify full system functionality and implement preventive measures, and 6. Document findings, actions, and outcomes.

Adım Adım Çözüm

1
Begin with problem identification
Information, symptom reports, and recent changes are gathered.
You must understand what is failing before forming hypotheses.
2
Formulate a probable cause theory
A prioritized hypothesis of the failure point is established.
Hypothesizing narrows down the operational scope before testing.
3
Test the theory
The root cause is verified (or disproved, triggering a new theory).
Changes should not be implemented without confirming the cause.
4
Plan and execute the solution
A plan of action is established and the fix is deployed.
Structured execution minimizes unwanted side effects during remediation.
5
Verify functionality and prevent recurrence
System operation is validated and preventive controls are applied.
Verification ensures the problem is fully resolved and won't immediately reoccur.
