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?
The goal of the question is to hope you skim through and read "ceiling" and select plenum. After reading it a few times and searching "ferrite core" it makes sense I guess point being it doesn't ask to prevent fire-safety, or to like protect the cable it's asking for the most likely option to prevent interference. **This question or close to it was on my 220-1001, another one I got wrong I see... heads up to anyone who expects to be tested on direct questions like what does a VGA cable do lol
Ferrite cores are used to suppress electromagnetic emissions by blocking low-frequency noise and absorbing high-frequency noise. This avoids electromagnetic interference.

Ferrite Core used to suppress high frequency devices. Its on the topic of EMI. So regarding the question this would be a close answer.
Actually, after more research, Ferrite Core makes more sense in terms of VGA cables. Here is a good example. Remember, the Tech is running a VGA cable anyways.
