devices?
A and B
B and C
C and D
A and D

D
4
Which statement is accurate about a WAN
link?
The link transmits data
serially.
The link uses a maximum
distance of 100 meters.
The link uses the same
transmission rate as all other WAN links use.
The link uses the same
standardized connector style that is used for all WAN
technologies.
5
Which statement describes a typical use of
Gigabit Ethernet?
to provide high-speed
desktop connectivity for average users
to provide connectivity
to low to medium volume applications
to provide medium
volume connectivity to workgroup servers
to provide high-speed
connectivity for backbones and cross
connects
6
What is characteristic of how a hub
operates?
A hub selectively drops
packets that represent potential security risks.
A hub forwards data out
all interfaces except the inbound interface.
A hub dynamically
learns the interfaces to which all devices are
attached.
At start up, a hub
queries the devices on all interfaces in order to learn
the MAC addresses of the attached devices.
A hub transmits a frame
to a specific interface based on the destination MAC
address.
7
At which layer of the OSI model does the
MAC address of a NIC reside?
physical
application
network
transport
data link
session
8
What device is used to connect hosts to an
Ethernet LAN and requires a straight-through UTP cable
between the hosts and this device?
NIC
router
switch
server
9
In which situations would a crossover
cable be used to connect devices in a network? (Choose
two.)
switch to PC
switch to hub
switch to router
switch to server
switch to
switch
10
Which of the following are benefits of a
wireless network? (Choose two.)
higher data
speeds
better security
mobility
less expensive NIC
cards
no need to run cables
to hosts
11
The ends of a UTP cable are shown in
the exhibit. Which cable configuration is
shown?
console
crossover
rollover
reversed-pair
split-pair
straight-through
12
Which two devices are considered OSI Layer
1 devices? (Choose two.)
hubs
routers
bridges
switches
repeaters
13
Refer to the exhibit. How many
collision domains exist in the network?
1
2
4
7
8
14
Which function is a unique
responsibility of the DCE devices shown in the
exhibit?
transmission of
data
reception of data
clocking for the
synchronous link
noise cancellation in
transmitted data
15
Refer to the exhibit. A technician
measured the lengths of the CAT 5e structured cable runs
in the exhibit. How should the technician evaluate the
cabling shown in the diagram to the network
administrator?
All cabling to work
areas are within specifications.
Station A and B may
experience intermittent problems because the length
exceeds the recommended standard.
Station B may
experience intermittent problems because the length
exceeds the recommended standard.
Station C may
experience intermittent network connectivity because the
length is less than the recommended standard.
Station A and B will
have intermittent problems because the length exceeds
the recommended standard.
Station C will not have
network connectivity because the length is less than the
recommended
standard.
16
What type of cable would be used to make
the connection between the console port of a router and
a workstation?
crossover
rollover
straight-through
patch
17
The ends of a UTP cable are shown in
the exhibit. Which cable configuration is
shown?
crossover
rollover
reversed-pair
straight-through
split-pair
console
18
Which address does a bridge use to make
filtering and switching decisions?
source MAC
source IP
destination MAC
destination IP
network IP
address
19
Refer to the exhibit. What is the
appropriate cable to use at each of the numbered network
connections?
Users with systems that are attached to a
hub are complaining about poor response time. What
device could replace the hub and provide immediate
response time improvement?
