CompTIA A+ Core 1 (220-1101) — Question 148

A new HD webcam's image only updates one or two times per second. The specifications indicate the webcam is capable of updating 30 frames per second. Which of the following is MOST likely causing the issue?

Answer options

• A. The USB 2.0 port has insufficient bandwidth.
• B. The Thunderbolt connector is not compatible.
• C. The VGA cable does not support a digital signal.
• D. The connection should use plenum instead of STP.

Correct answer: A

Explanation

The correct answer is A because USB 2.0 has limited bandwidth, which can restrict the data transfer rate required for 30 frames per second. Option B is incorrect as Thunderbolt is not relevant to USB webcam performance. Option C is irrelevant since the webcam does not utilize a VGA cable, and option D is not applicable as plenum and STP relate to network cabling rather than webcam functionality.
