Difficulty: Very hardTroubleshooting Methodology

An IT technician is resolving an issue on a critical engineering workstation that experiences system instability during CAD rendering. The technician interviewed the user, reviewed system event logs, and suspected a newly installed graphics driver update was causing memory allocation faults. In a controlled test environment, the technician successfully verified this hypothesis by rolling back the driver to a previous stable version, which completely eliminated the instability. According to the CompTIA troubleshooting methodology, which of the following actions should the technician perform NEXT?

  1. Establish a plan of action to resolve the issue on the production system and implement the solution.Answer
  2. B
    Deploy a domain Group Policy object to block all automatic graphics driver updates enterprise-wide.
  3. C
    Replace the high-performance graphics card hardware and run stress-testing diagnostics.
  4. D
    Reconfigure the local DNS server settings to assign a static IP address to the workstation.

Answer

Establish a plan of action to resolve the issue on the production system and implement the solution.
The technician has completed Step 3 (Test the theory to determine cause) by confirming that rolling back the graphics driver resolves the rendering crashes. According to the CompTIA troubleshooting framework, the immediate next step is Step 4: Establish a plan of action to resolve the problem and implement the solution.

Step-by-Step Solution

1
Identify the current stage in the 6-step CompTIA Troubleshooting Methodology based on the scenario.
The technician identified the problem (Step 1), formed a theory (Step 2), and verified the theory in a test environment (Step 3).
Verifying that driver rollback resolves the crash confirms the root cause.
2
Determine the mandatory next step in the standard sequence.
Step 4 is 'Establish a plan of action to resolve the problem and implement the solution'.
A plan must be outlined (including potential impact and rollback strategy) before applying the resolution to production systems.
