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
Answers Explanation & Hints:

Copper media is widely used in network communications. However, copper media is limited by distance and signal interference. Data is transmitted on copper cables as electrical pulses. The electrical pulses are susceptible to interference from two sources:
Electromagnetic interference (EMI) or radio frequency interference (RFI) – EMI and RFI signals can distort and corrupt the data signals being carried by copper media.
Crosstalk – Crosstalk is a disturbance caused by the electric or magnetic fields of a signal on one wire interfering with the signal in an adjacent wire.
