Show answer and explanation
Correct answer: A
Explanation
A yellow exclamation mark in Device Manager typically indicates a problem with the device driver. The most appropriate action is to update the driver to attempt to resolve the issue. If the problem persists after updating the driver, further troubleshooting steps can be taken, such as checking hardware connections or replacing the device.
- A. Correct.
Updating the webcam driver through Device Manager is the most logical step since the yellow exclamation mark indicates a driver issue or misconfiguration.
- B. Incorrect.
Replacing the webcam without further troubleshooting is premature and unnecessary at this stage.
- C. Incorrect.
While unplugging and replugging the webcam might resolve some connection issues, the yellow exclamation mark specifically indicates a driver-related problem, not a hardware connection issue.
- D. Incorrect.
Restarting the video conferencing application is unlikely to fix a driver-related issue indicated by the yellow exclamation mark in Device Manager.
