Zorluk: OrtaCompTIA Troubleshooting Methodology

A network administrator is troubleshooting an issue where containerized API gateways fail to communicate with an internal microservice cluster across a virtual overlay network. The administrator established a theory that an overly restrictive container firewall policy was blocking traffic and verified this theory by temporarily allowing all traffic, which immediately restored connectivity. Which of the following actions should the administrator take in the immediate next phases of the CompTIA troubleshooting methodology? (Select TWO.)

  1. Formulate a detailed plan of action to configure granular port rules while evaluating potential impact on overall application security.Cevap
  2. Execute the planned firewall rule updates to permanently re-enable secure microservice communication.Cevap
  3. C
    Perform end-to-end API transaction testing to verify that full system functionality has been restored.
  4. D
    Record the root cause analysis, modified security policies, and incident ticket details in the organizational knowledge base.

Cevap

The administrator should formulate a detailed plan of action while evaluating potential security impacts, and then execute the planned firewall rule updates.
According to the CompTIA troubleshooting methodology, once a technician tests a theory and confirms the root cause (Step 3), they must establish a plan of action to resolve the problem while identifying potential effects (Step 4), and then implement the solution (Step 5). Formulating a detailed plan of action with port rules and executing those planned updates correspond directly to these two sequential phases.

Adım Adım Çözüm

1
Determine the completed step in the CompTIA troubleshooting methodology.
The administrator completed Step 3 (Test the theory to determine cause) by temporarily allowing traffic to confirm the hypothesis.
Identifying the current position in the sequence determines which steps logically follow.
2
Identify the immediate next steps in the official methodology sequence.
The next sequential steps are Step 4 (Establish a plan of action to resolve the problem and identify potential effects) and Step 5 (Implement the solution or escalate as necessary).
CompTIA guidelines require creating a plan and considering potential side effects before implementing a permanent resolution.
3
Match the scenario options to the required methodology steps.
Formulating a detailed plan considering security impact maps to Step 4, and executing the planned updates maps to Step 5.
System verification (Step 6) and documentation (Step 7) take place later in the methodology lifecycle.
