Show answer and explanation
Correct answer: A
Explanation
The yellow triangle in Device Manager indicates a problem with the device, often related to the driver. Since the issue began after a recent update, rolling back to the previous driver version is the most appropriate solution. This action reverts the driver to a state that was working correctly, resolving the issue without introducing new variables.
- A. Correct.
Rolling back the printer driver to a previous version is the best option because the issue occurred after a recent driver update, indicating the new driver may be faulty or incompatible.
- B. Incorrect.
Disabling and re-enabling the device may refresh its state, but it will not resolve issues caused by a faulty driver update.
- C. Incorrect.
Uninstalling the device may temporarily fix the issue, but the same problematic driver could be reinstalled, leading to the same problem.
- D. Incorrect.
While updating to the latest driver is generally a good practice, in this case, the issue arose after a recent update, so the latest driver might already be causing the problem.
