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
What are two advantages of using fiber-optic cabling instead of UTP? (Choose two.)
easer to install
allows longer distances*
less effected by external signals*
easier to terminate the cable ends
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.
Which wireless standard operates in the 5 GHZ transmission range and is capable of 54 Mbps of data throughput?
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.

A=crossover, B=straight, C=straight
A=crossover, B=straight, C=rollover*
A=straight, B=crossover, C=rollover
A=rollover, B=straight, C=crossover
What factors should be considered when selecting the appropriate cable for connecting a PC to a network? (Choose two.)

Which Ethernet implementation requires the signal on the media to be boosted at a maximum distance of 100 meters?
When is a straight-through cable used in a network?
when configuring a router
