which of the following are characteristics of a coaxial network cable? (select two.) it has conductors that are twisted around each other to eliminate crosstalk. it is made of plastic or glass in the center. it has a conductor made from copper in the center. it uses two concentric metallic conductors. it is totally immune to electromagnetic interference (emi). i want to review this question later. (optional)

Answer

Brief Explanations:

Coaxial cables have two concentric metallic conductors - an inner conductor and an outer shield. The outer shield helps in reducing electromagnetic interference (but not making it totally immune). Also, the conductors are not twisted to eliminate crosstalk (twisted - pair cables do that), and they are not made of plastic around the center. The inner conductor is usually made of copper.

Answer:

It has a conductor made from copper in the center. It uses two concentric metallic conductors.
