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.

4. Which wireless standard operates in the 5 GHZ transmission range and is capable of 54 Mbps of data throughput?
• 802.11
• 802.11a
• 802.11b
• 802.11g

5. 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.

6.
