Copper Wiring Troubleshooting

What can be used instead of copper cables to protect against EMI/RFI?

• Fiber optic cables

• Aluminum cables

• Coaxial cables

• Unshielded twisted pair cables

How can crosstalk between wire pairs be reduced?

• By using longer cables

• By increasing the temperature

• By twisting wires into pairs

• By using unshielded cables

What is a common use for Power over Ethernet (PoE)?

• To enhance cable durability

• To reduce electromagnetic interference

• To increase data transfer speed

• To power devices where access to a power outlet is not available

What exacerbates attenuation in copper wiring?

• Using fiber optic cables

• Lower temperature

• Shorter cable length

• Higher temperature

What is the measure of resistance within the transmission medium known as?

• Crosstalk

• Attenuation

• Throughput

• Impedance

What does throughput refer to in networking?

• The resistance within the transmission medium

• The rate signals are processed and delivered

• The interference from external signals

• The loss of signal strength

What happens in a short circuit within twisted pair wiring?

• The signal becomes encrypted

• The signal stops completely

• The signal takes an unintended path

• The signal strength increases

What is an open circuit in the context of copper wiring?

• A cut in the wire preventing the signal from reaching the end

• A signal being enhanced

• A signal taking an unintended path

• A signal being reflected back to the transmitter

What is a miswired cable?

• A cable with reduced impedance

• A cable designed for fiber optic use only

• A cable with incorrect wire positions on connectors

• A cable with enhanced signal strength
