Zorluk: OrtaCompTIA Troubleshooting Methodology

A network administrator has confirmed through diagnostic testing that an outdated firmware version on a core distribution switch caused intermittent BGP route flapping. Having confirmed this theory, the administrator is now preparing to execute the 'Establish a plan of action to resolve the problem and identify potential effects' step in the CompTIA troubleshooting methodology. Which of the following specific tasks should be conducted as part of this step? (Select TWO)

  1. Identify potential side effects and downstream consequences of upgrading the switch firmware during production hours.Cevap
  2. Develop a detailed rollback procedure to restore previous operations if the firmware installation fails.Cevap
  3. C
    Interview affected users and gather baseline packet captures to isolate when the routing drops started occurring.
  4. D
    Perform complete end-to-end verification testing and deploy preventive monitoring rules across all adjacent routers.
  5. E
    Update the enterprise change management ticket with root cause analysis and log entries for historical reference.

Cevap

The correct actions are identifying potential side effects/downstream impacts of the switch firmware upgrade and developing a detailed rollback procedure to restore previous operations if the installation fails.
Establishing a plan of action (Step 4) specifically involves designing a clear, step-by-step remediation path, assessing potential side effects on network infrastructure, and preparing rollback/contingency plans prior to making changes.

Adım Adım Çözüm

1
Analyze the target phase of the CompTIA Troubleshooting Methodology
The current scenario is at Step 4: Establish a plan of action to resolve the problem and identify potential effects.
The technician has already identified the problem (Step 1), established a theory (Step 2), and tested the theory to confirm the cause (Step 3).
2
Evaluate candidate troubleshooting tasks against Step 4 requirements
Establishing a plan of action requires building a structured remediation plan, analyzing potential side effects, and creating a backup/rollback plan before implementation.
Anticipating unintended consequences and establishing contingency rollback plans ensures operational continuity during implementation.
3
Filter out tasks belonging to other methodology phases
User interviews (Step 1), full system verification/prevention (Step 5), and ticketing documentation (Step 6) are placed in different phases of the 6-step framework.
CompTIA methodology strictly sequences tasks to prevent unnecessary risk or premature action.
