CompTIA A+ Core 2 (220-1102) — Question 88

A technician is troubleshooting a lack of outgoing audio on a third-party Windows 10 VoIP application. The PC uses a USB microphone connected to a powered hub. The technician verifies the microphone works on the PC using Voice Recorder. Which of the following should the technician do to solve the issue?

Answer options

• A. Remove the microphone from the USB hub and plug it directly into a USB port on the PC.
• B. Enable the microphone under Windows Privacy settings to allow desktop applications to access it.
• C. Delete the microphone from Device Manager and scan for new hardware.
• D. Replace the USB microphone with one that uses a traditional 3.5mm plug.

Correct answer: A

Explanation

The correct action is to remove the microphone from the USB hub and connect it directly to the PC because powered hubs can sometimes introduce latency or connectivity issues. Enabling the microphone in Windows Privacy settings (option B) is not necessary since it has already been verified to work with Voice Recorder. Deleting the microphone from Device Manager (option C) may not address the root cause, and replacing the microphone with a 3.5mm plug (option D) is not needed as the USB microphone is functional.
