Zorluk: OrtaCompTIA Troubleshooting Methodology

A network technician is investigating an issue where wireless VoIP handsets drop calls when roaming between access points in a newly constructed distribution center. The technician established a theory that 802.11r fast transition roaming was omitted from the new access point WLAN profile, tested this theory in a staging environment, and confirmed the cause. According to the CompTIA troubleshooting methodology, which of the following tasks should the technician perform NEXT? (Select TWO).

  1. Develop a detailed plan of action to modify the wireless controller profile to enable fast transition roaming.Cevap
  2. Identify potential side effects and operational impacts on legacy wireless clients prior to executing the change.Cevap
  3. C
    Conduct roaming tests with handsets across all distribution center zones to confirm call continuity.
  4. D
    Update the central ticketing system with the root cause, configuration steps, and final resolution details.

Cevap

The technician should develop a detailed plan of action to modify the wireless controller profile and identify potential side effects on legacy wireless clients.
Once a theory of probable cause has been tested and confirmed (Step 3), the technician must proceed to Step 4 of the CompTIA troubleshooting methodology: Establish a plan of action to resolve the problem and identify potential effects. Developing a detailed configuration plan for the wireless controller and analyzing potential impacts on legacy devices represent the two core responsibilities of this step.

Adım Adım Çözüm

1
Identify current phase in CompTIA 7-step methodology
The technician has completed Step 3 (Test the theory to determine cause) by confirming the theory in a test environment.
Determining the current phase dictates what phase must logically follow.
2
Determine the next sequential phase
Step 4 is 'Establish a plan of action to resolve the problem and identify potential effects'.
CompTIA methodology strictly follows: 1. Identify problem → 2. Establish theory → 3. Test theory → 4. Plan of action & identify potential effects → 5. Implement solution → 6. Verify system functionality → 7. Document findings.
3
Select matching actions for Step 4
Formulating the deployment plan for enabling 802.11r and analyzing how legacy devices might react are both components of Step 4.
Planning changes and assessing risk/effects must occur before deploying changes to live infrastructure.
