1.

What are two advantages of using UTP cable in a networking environment? (Choose two.)
	is stiffer than STP
	is less expensive than fiber
	is easier to install than coaxial
	provides longer distances than coaxial provides
	is less susceptible to outside noise sources than fiber is

2.

What are two advantages of using fiber-optic cabling instead of UTP? (Choose two.)
	lower cost
	easer to install
	allows longer distances
	less effected by external signals
	easier to terminate the cable ends

3.

What is the difference between a wireless NIC and an Ethernet NIC?
	The Ethernet NIC operates at 100 Mbps, whereas a wireless NIC operates at 10 Mbps.
	The Ethernet NIC uses a PCI expansion slot, and a wireless NIC cannot use an expansion slot.
	The wireless NIC uses CSMA/CA, whereas a Ethernet NIC uses token passing as an access method.
	The wireless NIC associates to an access point, and an Ethernet NIC attaches to a hub or switch using a cable.
	The Ethernet NIC attaches to a hub or a switch using only fiber cabling, and a wireless NIC attaches to a wireless antenna using air as a network medium.

A company is converting a cabled LAN to a wireless Ethernet LAN. What must be changed on every host on the network?
	No changes are required.
	Each host will require a new IP address.
	Each host will require an appropriate NIC or adapter.
	Each host will require that the operating system be upgraded.
