What factors should be considered when
selecting the appropriate cable for connecting a PC to a
network? (Choose two.)
type of system
bus
motherboard model
distance of cable
run
speed of
transmission
computer
manufacturer
2
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
3
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.
4
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.

8
Which of the following are used for data
communication signals? (Choose three.)

10
Refer to the exhibit. What type of
cable connects the two routers together without any
intermediary device?
console

11
When is a straight-through cable used in a
network?
when configuring a
router
when connecting a host
to a host
when connecting a
switch to a router
when connecting one
switch to another
switch
12
What does UTP cable rely on to reduce
signal degradation caused by EMI and RFI?
shielding
magnetism
cancellation
insulation
properly grounded
connections
RJ-45
connectors
13
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
14
Which Ethernet implementation requires the
signal on the media to be boosted at a maximum distance
of 100 meters?
10BASE2
10BASE5
100BASE-T
100BASE-FX
1000BASE-CX
15
