3. What is the
difference between a wireless NIC and an Ethernet NIC?
a. The
Ethernet NIC operates at 100 Mbps, whereas a wireless NIC operates at 10 Mbps.
b. The
Ethernet NIC uses a PCI expansion slot, and a wireless NIC cannot use an
expansion slot.
c. The
wireless NIC uses CSMA/CA, whereas a Ethernet NIC uses token passing as an
access method.
d. The
wireless NIC associates to an access point, and an Ethernet NIC attaches to a
hub or switch using a cable.#
e. 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. Refer to the exhibit. The JacksCo is a small start-up
company that took over an office space from another small company that closed.
The older company left a room of network equipment behind. An inventory list is
shown. As the newly hired network technician, you have been asked to determine
which components in the storeroom would be best to use to install a small
wireless LAN that currently only needs the employees to be able to share data.
Note that the wireless LAN also needs to connect to an existing wired LAN.
Which components should you choose?
a. access
point and wireless NICs
b. wireless
NICs, access point, straight-through cables, and a switch
c. hub,
wireless NICs, two wireless bridges, crossover cables, and an access point
d. wireless
NICs, Ethernet NICs, a switch, an external modem, two wireless bridges
e. Ethernet
NICs, wireless NICs, switch, hub, two wireless bridges, straight-through
cables, crossover cables, and a router

converting a cabled LAN to a wireless Ethernet LAN. What must be changed on
every host on the network?
a. No
changes are required.
b. Each
host will require a new IP address.
c. Each
host will require an appropriate NIC or adapter.#
d. Each
host will require that the operating system be upgraded.
6. Refer to the
exhibit. Which answer correctly identifies the pinout of the UTP cables labeled
Cable A, Cable B, and Cable C?

b.
A=rollover, B=crossover, C=straight
c.
A=crossover, B=straight, C=straight
d.
A=crossover, B=straight, C=rollover#
e.
A=straight, B=crossover, C=rollover
f.
A=rollover, B=straight, C=crossover
7. What factors
should be considered when selecting the appropriate cable for connecting a PC
to a network? (Choose two.)
a. type of
system bus
b.
motherboard model
c. distance
of cable run#
