Which of the following types of network cable is made up of a single copper conductor at its center and a plastic layer that provides an insulated center conductor with a braided metal shield?

Show Suggested Answer Hide Answer
Suggested Answer: B

A coaxial cable is a type of network cable that is made up of a single copper conductor at its center and a plastic layer that provides an insulated center conductor with a braided metal shield. The metal shield helps to reduce electromagnetic interference and noise from external sources. Coaxial cables are commonly used for cable TV, radio, and broadband internet connections12.

I’m pretty sure fiber optic isn’t correct since it uses glass, but I can't recall the specifics about coaxial.

I’m a bit confused because I remember unshielded twisted pair and shielded twisted pair, but I don’t think they fit this description.

I practiced a similar question last week, and I think coaxial was the one with the braided shield. So, I’m leaning towards B.

I think the answer might be coaxial, but I'm not entirely sure. I remember something about it having a single copper conductor.

Ah, I remember learning about this in class. The description matches shielded twisted pair, so I'll select option D.

Okay, let me think this through. The key details are a single copper conductor, a plastic insulating layer, and a braided metal shield. That sounds like shielded twisted pair to me.

Hmm, I'm a bit unsure about this one. I know coaxial and fiber optic have different structures, but I'm not totally confident in my knowledge of the different twisted pair cables.

I'm pretty sure this is describing a shielded twisted pair (STP) cable, so I'll go with option D.

Hmm, I'm a bit unsure about this one. Virtual network isolation is an important topic, but the options don't seem entirely clear to me. I'll need to think it through step-by-step.
