Zorluk: KolayTroubleshooting Methodology

A network support technician is assigned to troubleshoot a workstation that suddenly lost connectivity to local network resources. Arrange the following troubleshooting steps in the correct sequential order according to the CompTIA 6-step troubleshooting methodology, starting from the first step.

  1. 1Question the user regarding recent changes and inspect the network connection status.
  2. 2Develop a hypothesis that a bent pin inside the wall port cable clip is preventing link negotiation.
  3. 3Temporarily plug the cable into a neighboring patch port to determine if link connectivity returns.
  4. 4Replace the damaged wall modular jack and re-terminate the Ethernet cabling permanently.
  5. 5Confirm the workstation obtains a valid IP address and verify the user can open remote shared folders.
  6. 6Log the incident cause, termination repair steps, and final verification outcome in the ticketing system.

Cevap

The correct order according to the CompTIA 6-step troubleshooting methodology is: (1) Question the user regarding recent changes and inspect the connection status; (2) Develop a hypothesis that a bent pin is preventing link negotiation; (3) Temporarily plug the cable into a neighboring patch port to test the theory; (4) Replace the damaged wall modular jack and re-terminate cabling; (5) Confirm valid IP configuration and verify remote shared folder access; and (6) Log the incident cause and repair steps in the ticketing system.
The correct sequence strictly follows the CompTIA standard: (1) Identify the problem by interviewing the user and observing symptoms, (2) Establish a theory of probable cause, (3) Test the theory to confirm the root cause, (4) Establish a plan of action and implement the solution, (5) Verify full system functionality, and (6) Document findings, actions, and outcomes.

Adım Adım Çözüm

1
Identify the problem.
Gathers background information and symptoms directly from the user and physical environment.
Troubleshooting must begin by defining the problem before attempting diagnostic tests.
2
Establish a theory of probable cause.
Formulates a logical hypothesis regarding the hardware failure.
Developing a plausible theory guides targeted testing.
3
Test the theory to determine cause.
Validates or refutes the hypothesis through quick diagnostic testing.
The theory must be confirmed prior to establishing a full repair plan.
4
Establish a plan of action to resolve the problem and implement the solution.
Executes the permanent physical repair.
Permanent fixes are implemented only after the cause is verified.
5
Verify full system functionality.
Ensures the original problem is resolved and no new issues were introduced.
System verification confirms normal user operations before closing out work.
6
Document findings, actions, and outcomes.
Records ticket details for future reference and organizational knowledge.
Documentation is always the final step in standard IT support workflows.
