CompTIA A+ Core 1 (220-1101) — Question 480

A laptop's external webcam software is running, but it shows no image or video. Which of the following should a technician perform FIRST?

Answer options

• A. Research new webcam firmware.
• B. Restart the computer and run system diagnostics.
• C. Reseat the webcam.
• D. Reinstall the webcam software and drivers.

Correct answer: C

Explanation

Reseating the webcam is the best initial step as it ensures a proper physical connection, which is often a simple fix for connectivity issues. Researching firmware or reinstalling software may be necessary later, but those steps are more complex and time-consuming compared to checking the hardware connection first. Restarting the computer could help, but it does not address possible hardware disconnection directly.
