Question 1:
What should be done when preparing to run cable?
Cut the
cable before pulling it.
Unroll it
before pulling it through the ceiling.
Label the boxes and cable.
Take the
cable out of the boxes.
Question 2:
How is an RJ-45 jack surface mounted?
with a
punch tool
with
Velcro
flush
with the surface
adhesive backed or screw box
Question 3:
Why is the wiring sequence critical when RJ-45 jacks are used at the
telecommunications outlet in a horizontal cabling scheme?
For the network to function properly.
Improper
wiring sequence will short out the connection.
You could
get a nasty electrical shock.
The
collision rate is adversely affected.
Question 4:
When should cable not be routed in an existing raceway?
if the
raceway distance exceeds 100 feet
if the
raceway material is partially metallic
if it already contains a power cable
if it
contains a telephone line
Question 5:
What kind of a cable must you use when laying cable through spaces where air is
circulated?
shielded
double
coated
fire rated
unshielded
Question 6:
What tool would you use to attach CAT5 cable to a patch panel?
110 patch
tool
cable
terminator
punch tool
patch
terminator
Question 7:
If you have one wiring closet and you want to add more, what name is given to
additional wiring closets?
IDFs
MDFs
Extended
Stars
POPs
Question 8:
When running cable from the wiring closet to wall jacks, where is the cable
itself labeled?
at each
tie
at each end
at the
jack end
at the
panel end
Question 9:
What type of raceway should be used if it will be visible in the room?
channel
guide
decorative
ladder
rack
gutter
Question 10:
Why are split pairs a problem for network installations?
The wires
are unshielded and easily lose synchronicity.
The wires are part of different circuits so
signals are not protected and cross-talk occurs.
The wires
are part of different circuits and easily shorted out by power spikes.
It is
difficult to detect split pairs which requires performing a wire map
Question 11:
All the items below are personal safety precautions before you install cable except :
Wear long
sleeves.
Wear long
pants.
Wear baggy clothes.
Check for
power cables.
Question 12:
Why is establishing a baseline performance level for a network important?
for
fulfilling one of the requirements necessary for you to get your network
certification
for
providing your client with proof of a successful installation
for future
periodic testing of the network and diagnostics
for
obtaining a network registration and identification number from TIA/EIA and
IEEE
Question 13:
What should be used to mount cable to a wall?
tie wraps
electrical tape
staples
paperclips
Question 14:
What is the most important thing to do before you work in walls, ceilings or
attics?
Label the
faceplate.
Measure
out the cable.
Turn off power to the area.
Install
the patch panel.
Question 15:
What is the first thing you should do if near-end crosstalk is detected?
Redo all
connections at the patch panel.
Isolate
which connection is the cause by running a TDR test.
Redo all
connections at the cross connects.
Visually check the horizontal cabling.
Question 16:
What kind of jack must be used for making a connection to a Category 5
unshielded twisted pair cable in a horizontal cabling scheme?
RJ-45
BNC
UTP 55
EIA 45
Question 17:
How many pins are on each of the ports of a patch panel?
4 pins
8 pins
11 pins
45 pins
Question 18:
Why shouldn't you install a jack in the bottom five centimeters of a wooden
baseboard?
The bottom plate of the wall will prevent you from
pushing the box into the baseboard.
Most
floors have metal supports that produce electromagnetic interference when close
to the jack.
Dust and
dirt accumulate under it that can then get into the connection and affect
network performance.
It's so
close to the floor, there isn't enough space for most people to work and
manipulate the wires.
Question 19:
What is the central junction for the network cable?
POP
server
center
point
wiring closet
Question 20:
What is one advantage of using distribution racks for mounting patch panels?
allows easy access to both the front and back of
the equipment
provides
neutral ground
inexpensive compared to brackets
requires
minimal wall space
Question 21:
Which of the following describes a cable tester measurement of signal
attenuation?
It measures
the reduction in power of a signal received from a signal injector.
It
measures the increase in power of a signal received from a signal injector.
The
signal injector attaches to the near end of the cable.
The
frequency to be used for testing is specified in EIA/TIA 568A.
Question 22:
How does a cable tester (a TDR) measure distance?
The cable
tester identifies signal degradation, indicating the cable is longer than the
acceptable maximum length.
It
determines the time a signal takes to be reflected back from closed-ended
cable.
It times the signal sent towards and reflected
back from the end of an open-ended cable.
It
measures the ability of other devices on the network to receive and send
signals through the cable.
Question 23:
Which of the following is a source that can produce interference on UTP cable?
fluorescent lights
fiber-optic cabling
bridges
coaxial
cabling
Question 24:
Which best describes a patch panel's function?
It serves
as a temporary fix to network problems.
It acts
as a router for temporary networks connecting the various devices often found
at conventions and shows.
It acts as a switchboard where horizontal cabling
from workstations can be connected to other devices to form a LAN.
It allows
the network administrator to test the entire network cabling from a single
location.
Question 25:
What is a rough diagram that shows where the cable runs are located called?
cut sheet
sketch
cable
plan
cabling
route
