What technique is used with UTP cable to help protect against signal interference from crosstalk?

• Twisting the wires together into pairs.

• Terminating the cable with special grounded connectors.

• Encasing the cables within a flexible plastic sheath.

• Wrapping a foil shield around the wire pairs.

Which statement describes crosstalk?

• The distortion of the network signal from fluorescent lighting.

• The distortion of the transmitted messages from signals carried in adjacent wires.

• The loss of wireless signal over excessive distance from the access point.

• The weakening of the network signal over long cable lengths.

Which statement correctly describes frame encoding?

• It generates the electrical, optical, or wireless signals that represent the binary numbers of the frame.

• It uses the characteristic of one wave to modify another wave.

• It transmits data signals along with a clock signal which occurs at evenly spaced time durations.

• It converts bits into a predefined code in order to provide a predictable pattern to help distinguish data bits from control bits.

Which statement describes throughput?

• The measure of the bits transferred across the media over a given period of time.

• The measure of the usable data transferred across the media.

• The theoretical capacity of a particular medium to carry data.

• The total amount of time it takes to get from one device to another.

What is the purpose of the OSI physical layer?

• Controlling access to media.

• Transmitting bits across the local media.

• Exchanging frames between nodes over physical network media.

• Performing error detection on received frames.

Which statement describes attenuation?

• The loss of wireless signal over excessive distance from the access point.

• The distortion of the network signal from fluorescent lighting.

• The weakening of the network signal over long cable lengths.

• The distortion of the transmitted messages from signals carried in adjacent wires.

Which statement describes bandwidth?

• The speed at which bits travel on the network.

• The theoretical capacity of a medium to carry data.

• The amount of data that can flow from across the internet in a given amount of time.
