Zorluk: Çok zorTroubleshooting Methodology

A system administrator has isolated an issue on a graphics workstation where internal PCI Express RAID storage disconnects under heavy load. The administrator tested a theory by swapping the RAID controller power lead to a separate, dedicated 12V PSU rail, which successfully confirmed that insufficient rail power was causing the dropouts. According to the CompTIA troubleshooting methodology, which TWO of the following actions should the technician perform NEXT before implementing preventative measures or closing the ticket? (Select TWO.)

  1. Establish a plan of action to replace or reconfigure the power supply unit and implement the solution.Cevap
  2. Verify full system functionality by subjecting the workstation to sustained heavy load stress testing.Cevap
  3. C
    Document the complete root cause, test results, and final solution in the ticketing system immediately before testing the implemented change.
  4. D
    Re-inquire about recent environmental changes with the workstation user to confirm if ambient heat caused the PSU rail degradation.

Cevap

The technician must establish a plan of action to replace or reconfigure the power supply unit to implement the fix, followed by verifying full system functionality under sustained heavy load stress testing.
In the CompTIA troubleshooting methodology, after a theory of cause is confirmed by testing (Step 3), the immediate next requirements are establishing a plan of action to resolve the problem and implementing the solution (Step 4), followed by verifying full system functionality (Step 5).

Adım Adım Çözüm

1
Analyze current phase in CompTIA 6-step methodology
The technician has completed Step 3 (Test the theory to determine cause) by confirming that inadequate power rail wattage caused the PCI Express RAID dropouts.
Confirming the theory completes Step 3.
2
Identify the next sequential step (Step 4)
Step 4 is establishing a plan of action to resolve the problem and implementing the solution.
Before functionality can be verified or documented, the permanent fix must be planned and executed.
3
Identify the following sequential step (Step 5)
Step 5 is verifying full system functionality and implementing preventive measures.
The system must be stress tested under original conditions to ensure stability before documenting and closing the issue.
