1. A technician is beginning work as an entry-level ICT installer on a
commercial building project and is expected to perform cable installation,
termination, and basic testing while following established installation
methods and job-site safety practices. Which responsibility most directly
aligns with the primary scope of a BICSI Installer 1?
A. Designing the complete telecommunications architecture for a
multibuilding campus
B. Installing, terminating, and testing ICT cabling according to applicable
methods and requirements
C. Programming enterprise network switches and routers after the cabling
work is complete
D. Performing advanced fiber characterization and certification for every
backbone link
Answer: B
2. During a commercial cabling installation, an installer must determine
whether a planned activity can proceed safely before beginning work. The
work area contains ladders, power tools, overhead pathways, and energized
electrical equipment. Which action should receive priority before cable
installation begins?
A. Begin pulling cable and identify hazards after the first cable is installed
B. Remove all existing telecommunications labels so new labels can be
installed later
C. Perform a site safety assessment and identify applicable hazards,
controls, and required personal protective equipment
D. Test every cable before determining whether the work area requires
additional protection
Answer: C
pg. 1
, 3. A four-pair balanced twisted-pair cable is being installed through a pathway
containing several bends. The installer wants to preserve the transmission
characteristics of the cable and prevent excessive mechanical stress. Which
practice is most appropriate?
A. Maintain the manufacturer's specified bend radius throughout the
installation
B. Compress the cable tightly against the inside of every bend to save
pathway space
C. Create sharp bends wherever necessary as long as the cable jacket
remains intact
D. Twist the cable repeatedly around the pathway to keep it separated from
other cables
Answer: A
4. An installer is preparing to pull a large communications cable through a
conduit. The route includes several bends, and excessive pulling force could
damage the cable or its internal conductors. Which procedure is most
appropriate before beginning the pull?
A. Pull the cable rapidly so it spends less time under tension
B. Remove the pull string because it can increase friction inside the conduit
C. Determine the permitted pulling tension and use an appropriate pulling
method and lubricant when permitted
D. Attach the cable directly to an electrical conductor already occupying the
conduit
Answer: C
5. A technician is working with a copper cable that must be terminated on an
insulation displacement connection block. The installer is preparing the
conductors for termination. Which practice is most appropriate?
A. Strip several inches of insulation from every conductor before placing
them on the block
B. Preserve the pair relationships and terminate conductors according to
the specified wiring scheme
C. Untwist every pair completely so the individual conductors can be
pg. 2
, arranged more easily
D. Cut off the cable jacket several feet from the termination point
Answer: B
6. During installation of four-pair balanced twisted-pair cable, an installer
notices that a large amount of pair twist has been removed near the
termination. The cable passes continuity testing, but the installer is
concerned about transmission performance. What is the primary reason
excessive untwisting should be avoided?
A. It can adversely affect electrical performance such as crosstalk and
impedance characteristics
B. It causes the cable jacket to become permanently fire resistant
C. It prevents the cable from being identified by its printed markings
D. It automatically changes the cable category designation
Answer: A
7. A technician is installing multiple horizontal cables above a suspended
ceiling and wants to support them without placing excessive pressure on
the cable jackets. Which installation method is generally appropriate?
A. Suspend the cables from sprinkler piping using metal wire
B. Attach the cables tightly to electrical conductors
C. Use approved telecommunications cable supports appropriate for the
installation
D. Lay the cables directly across ceiling tiles so they cannot move
Answer: C
8. An installer discovers that a communications cable has been sharply kinked
while being pulled into a pathway. The jacket appears intact, but the cable
no longer has its original shape. What should the installer do?
A. Hide the damaged section inside the pathway because the jacket is not
broken
B. Straighten the cable by sharply bending it in the opposite direction
C. Continue pulling because physical deformation cannot affect
communications performance
pg. 3
, D. Evaluate the cable according to applicable requirements and replace the
damaged section when necessary
Answer: D
9. A technician is preparing a cable pull and needs to keep the cable from
being damaged as it enters a conduit. Which consideration is most
important at the conduit entrance?
A. Ensure the cable encounters a smooth transition without sharp edges
that could damage the jacket
B. Remove the cable jacket before entering the conduit
C. Increase pulling tension until the cable slides quickly through the
entrance
D. Place the cable against the sharpest edge so that it remains centered
Answer: A
10. A technician needs to determine the approximate length of an installed
copper cable and identify the location of a possible discontinuity. Which
instrument is specifically suited to measuring distance to cable events by
analyzing reflected signals?
A. Tone generator
B. Visual fault locator
C. Time-domain reflectometer
D. Optical power meter
Answer: C
11. A four-pair copper cable must be terminated on a modular connector. The
installer is deciding whether to use the T568A or T568B wiring scheme.
Which principle should guide the selection?
A. Always change the wiring scheme between the two ends to improve
performance
B. Use the specified wiring scheme consistently at the required termination
points
C. Select the scheme based solely on the color of the cable jacket
D. Randomly select the conductor order because modern equipment
