CompTIA A+ 220-1102 Practice Question

The correct answer is Update the device driver because typically when a device is not functioning correctly and has a yellow exclamation mark in Device Manager, it is often due to outdated, missing, or corrupted drivers. Updating the driver can resolve these issues and potentially fix the instability problem. Rolling back the driver may be appropriate if the issue started after a recent driver update, but it is not the most immediately fitting step without that context. Disabling the device is a possible troubleshooting step but it will elude resolving the actual problem with the device and can lead to loss of functionality. Uninstalling the device can be a more drastic step and could be considered if updating the driver does not work; however, this could also result in additional issues if the device does not reinstall correctly. That makes updating the device driver the best first action.
