CompTIA A+ Core 1 (220-1101) — Question 539

While using a popular videoconferencing program, the user selects a webcam, but the software is unable to open the webcam. The webcam was working the previous day. Which of the following should be done to address this issue?

Answer options

• A. Close other video software and retry.
• B. Adjust the conference software to a compatible resolution.
• C. Switch the video from the webcam to ג€conferenceג€ mode.
• D. Reseat or replace the webcam.

Correct answer: A

Explanation

The correct answer is A because other video software may be using the webcam, preventing the conferencing app from accessing it. The other options, while potentially useful in different contexts, do not directly address the likely cause of the issue, which is resource contention.
