What are two characteristics of fiber-optic cable? (Choose two.)

• It is not affected by EMI or RFI.

• Each pair of cables is wrapped in metallic foil.

• It combines the technique of cancellation, shielding, and twisting to protect data.

• It typically contains 4 pairs of fiber-optic wires.

• It is more expensive than UTP cabling is.

With the use of unshielded twisted-pair copper wire in a network, what causes crosstalk within the cable pairs?

• the magnetic field around the adjacent pairs of wire

• the use of braided wire to shield the adjacent wire pairs

• the reflection of the electrical wave back from the far end of the cable

• the collision caused by two nodes trying to use the media simultaneously

• STP

• UTP

• fiber

• coaxial

In addition to the cable length, what two factors could interfere with the communication carried over UTP cables? (Choose two.)

• crosstalk

• bandwidth

• size of the network

• signal modulation technique

• electromagnetic interference
