Difficulty: EasyCompTIA Troubleshooting Methodology

After conducting diagnostic tests on a malfunctioning core switch, a systems engineer confirms their theory that a corrupted firmware image is causing routing table drops. Following the CompTIA troubleshooting methodology, which of the following actions should the engineer take next? (Select TWO.)

  1. Establish a plan of action to resolve the issue while identifying potential side effects.Answer
  2. Implement the resolution or escalate the issue as necessary to restore normal operation.Answer
  3. C
    Verify full system functionality by conducting end-to-end connectivity tests across affected subnets.
  4. D
    Document the final findings, actions taken, and outcomes in the ticketing system.

Answer

The engineer should establish a plan of action while considering potential effects, and implement the solution or escalate as necessary.
Once a theory of probable cause has been tested and confirmed, the CompTIA troubleshooting methodology dictates moving to Step 4: Establish a plan of action to resolve the problem and implement the solution. This step encompasses formulating a detailed plan while considering potential effects and carrying out the necessary implementation or escalation.

Step-by-Step Solution

1
Identify the completed step in the CompTIA troubleshooting sequence.
The engineer has established and successfully tested/confirmed the theory of probable cause (Step 3 complete).
Identifying the current progress pinpoints where the technician stands in the methodology.
2
Identify the immediate next step in the methodology.
Step 4 requires establishing a plan of action to resolve the problem and implementing the solution.
CompTIA process rules mandate that planning resolution steps, identifying potential effects, and implementing the fix must occur before verification or documentation.
3
Select the correct actions corresponding to Step 4.
Developing a plan of action with side-effect consideration and executing/escalating the implementation represent the valid actions for this step.
Actions such as system verification (Step 5) and documentation (Step 6) cannot be performed out of sequence.
