TestOut Network Pro Chapter 2

Why are the pairs twisted in Ethernet cables?

• To keep the pairs together

• So that two separate signals can be sent at the same time

• To provide data on one wire and power on the other

• To reduce cross talk between wires

How many pairs of wire are their in an Ethernet cable?

• Two

• Four

• Six

• Eight

Why are the pairs of wires twisted differently?

• To reduce the cross talk between pairs of wires

• So that each pair can be identified more easily

• To make it easier to crimp the wires

• No particular reason

Which one item below is NOT a benefit of using twisted pair cables?

• Flexibility

• Lower Cost

• Ease of use

• Not susceptible to EMI

Which of the following is a disadvantage of using twisted pair cables?

• Very expensive

• Hard to use

• Susceptible to eavesdropping

• Works with the newer protocols.

What does UTP stand for?

• Unconfirmed Transmission Protocol

• Ultra Terminated Pair

• Uniform Transmission Protocol

• Unshielded Twisted Pair

Which type of cable would you use in a drop ceiling with many florescent lights?

• UTP Plenum

• STP Plenum

• UTP Riser

• STP Riser

Which fact about a Plenum cable is True?

• It is non-toxic when burned

• It is the least expensive cable

• It can only be used for vertical runs

• It uses special connectors, not RJ45

Which type of wires conduct electricity better (assuming they are the same Gage wire)?

• Stranded copper wire

• Solid copper Wire

• Plastic core wire

• They all conduct equally

Which type of wire is more flexible and least likely to break with repetitive movements?

• Stranded core wire

• Solid core wire
