What is the last step a technician should take when resolving digital video quality issues?

The last step a technician should take when resolving digital video quality issues is to verify problem resolution. This step is crucial as it ensures that the actions taken to address the issue were effective and that the digital video quality has indeed improved. By verifying the resolution, the technician can confirm that the solution has resolved the initial problem and that everything is functioning as expected.

Monitoring system performance is important but typically occurs while troubleshooting and not as a concluding step. Documenting the issue is essential for record-keeping and future reference, but it should be done after verification to ensure that the documentation reflects the current status of the issue. Checking for customer satisfaction, while also important, comes after confirming that the problem has been resolved, as it is more meaningful when the solution is verified. Verifying problem resolution ultimately solidifies the troubleshooting process, ensuring that the technician can confidently conclude their work.
