After implementing a corrective action in a troubleshooting process, which step should be performed next?

• A. Document findings
• B. Verify functionality
• C. Plan action
• D. Identify the problem

Answer: (B)

Verifying functionality is the immediate next step after implementing a corrective action because you need concrete evidence that the fix actually resolves the issue without causing new problems. This involves re-testing the scenario that failed, ensuring the impacted service or device operates correctly under normal conditions, and checking related components or logs for stability. Only when the fix is confirmed working do you proceed to document what was done and close the troubleshooting ticket. If verification shows issues still exist, you revisit and adjust the solution. The earlier steps focused on identifying the problem and planning the action, so verification is the essential checkpoint to validate success before moving on.
