CompTIA A+ Core 1 (220-1001) — Question 194

A technician is selecting a long VGA cable to run through the walls and ceiling to a projector. Which of the following cable features will help minimize interference with the video signal?

Answer options

• A. Ferrite core
• B. Copper conductors
• C. Plenum
• D. Fiber

Correct answer: A

Explanation

The ferrite core helps to filter out high-frequency noise and electromagnetic interference, thereby enhancing the integrity of the video signal over long distances. While copper conductors are essential for signal transmission, they do not specifically minimize interference. Plenum refers to the type of cable suitable for air handling spaces, and fiber is not applicable in this context as VGA uses copper cabling.
