Question

Difficulty: MediumCompTIA Troubleshooting Methodology

A network specialist investigating a high-availability BGP routing incident has completed testing a hypothesis in a sandbox environment, confirming that an unannounced AS-path prepending modification by an upstream provider caused asymmetric routing drops. Having confirmed the root cause, the specialist is preparing for the next phase of the CompTIA troubleshooting methodology. Which TWO of the following actions should the specialist perform during this next phase? (Select TWO.)

  1. A
    Document the vendor change details, root cause analysis, and resolution history in the central knowledge base.
  2. Evaluate potential impacts on downstream network traffic and create a detailed procedure for applying the route-map adjustment.Answer
  3. Schedule and execute the route-map configuration change according to change management control procedures.Answer
  4. D
    Perform packet captures across redundant core interfaces to confirm that traffic symmetry has been restored across all active paths.

Answer

The specialist should evaluate potential impacts on downstream traffic while formulating the detailed modification steps, and schedule and execute the route-map configuration change within established change control procedures.
After testing a theory to confirm the root cause (Step 3), the technician must advance to Step 4 of the CompTIA troubleshooting methodology: establishing a plan of action to resolve the problem and identifying potential effects, then implementing the solution. Evaluating potential downstream traffic impacts during procedure creation and executing the route-map modification under change control procedures are the direct components of Step 4.

Step-by-Step Solution

1
Identify the completed stage in the CompTIA troubleshooting framework.
Testing the hypothesis in the sandbox environment to confirm the root cause represents Step 3 (Test the theory to determine cause).
Determining which step has just finished sets the baseline for identifying the immediate next step in the standard sequence.
2
Determine the next sequential phase of the methodology.
The next step is Step 4: Establish a plan of action to resolve the problem and identify potential effects, followed by implementing the solution or escalating as necessary.
CompTIA methodology strictly follows: 1. Identify problem → 2. Establish theory → 3. Test theory → 4. Plan of action & implement → 5. Verify system functionality → 6. Document findings.
3
Select the specific actions that belong within Step 4.
Formulating the plan while evaluating potential downstream impacts and executing the implementation through change management are the two correct actions for Step 4.
Planning for side effects and carrying out the implementation under change control directly fulfill the requirements of Step 4.
