4. 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

14. Which characteristics describe 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 has a maximum speed of 100 Mbps.

It is the most expensive type of LAN cabling.

 

15. Which of the following is a characteristic of single-mode fiber-optic cable?

generally uses LEDs as the light source

relatively larger core with multiple light paths

less expensive than multimode

generally uses lasers as the light source

 

16. What is considered a benefit of wireless as a media choice?

more host mobility

lower security risks

reduced susceptibility to interference

less impact of the surroundings on the effective coverage area

 

17. What characteristic of UTP cable helps reduce the effects of interference?

the metal braiding in the shielding

the reflective cladding around core

the twisting of the wires in the cable

the insulating material in the outer jacket

 

18. What is a primary role of the Physical layer in transmitting data on the network?

create the signals that represent the bits in each frame on to the media

provide physical addressing to the devices

determine the path packets take through the network

control data access to the media

  14. medo says:

    A customer installs a wireless access point at home in the closet next to the kitchen. The customer mentions that the wireless communication performance seems degraded when the cordless phone or the microwave oven is in use. What is the possible reason for this degradation?
    The access point is close to walls.
    The cordless phone joins the WLAN and shares the available bandwidth.
    The wireless signal is in the same radio frequency range as the household devices are in.
    The access point is on the same electrical circuit as the phone base unit and microwave oven are.
    The surge of electricity when a microwave oven is in use disrupts the operation of the access point.
