1.
A technician is installing communication cabling in a commercial building and
must maintain proper separation from power conductors. What is the primary
reason?
A. To increase cable jacket thickness
B. To reduce electromagnetic interference and improve communication signal
integrity
C. To eliminate the need for grounding
D. To increase network bandwidth
Answer: B
Rationale: Separating communication wiring from electrical power conductors
helps reduce electromagnetic interference, induced noise, and potential
communication performance problems.
2.
During installation of a communications cable, the technician discovers that the
cable manufacturer's minimum bend radius has been exceeded. What should
happen?
,A. Continue because communication cables are flexible
B. Add electrical tape around the bend
C. Replace or reposition the cable to maintain the manufacturer's specified bend
radius
D. Increase the cable pulling tension
Answer: C
Rationale: Excessive bending can deform cable geometry, damage internal
conductors, increase attenuation, and negatively affect transmission
performance.
3.
Which device primarily provides a centralized connection point for horizontal
communication cabling within a telecommunications room?
A. Patch panel
B. Smoke detector
C. Circuit breaker
D. Transformer
Answer: A
Rationale: A patch panel organizes and terminates multiple communication
cables while providing convenient connections to network equipment.
4.
,A communications installer needs to identify individual copper conductors before
terminating them into a connector. Which resource should be consulted?
A. Fire extinguisher inspection tag
B. Lighting schedule
C. Mechanical equipment schedule
D. Applicable cable color-code or wiring standard
Answer: D
Rationale: Standardized color identification allows technicians to terminate
conductors consistently and prevents polarity, pair, or circuit identification errors.
5.
Why should communication cables generally not be installed under excessive
pulling tension?
A. Excessive tension can damage conductors, insulation, shielding, or cable
geometry
B. It automatically increases network speed
C. It makes grounding unnecessary
D. It improves connector retention
Answer: A
Rationale: Excessive pulling force can stretch or deform communication cables,
causing permanent performance degradation and possible conductor damage.
, 6.
A technician is terminating twisted-pair cable and notices that excessive
untwisting has occurred near the connector. What concern exists?
A. Increased fire resistance
B. Reduced cable diameter
C. Increased electrical service voltage
D. Increased susceptibility to crosstalk and degraded transmission performance
Answer: D
Rationale: Maintaining pair twisting close to the termination helps preserve
electrical characteristics and limits unwanted crosstalk between pairs.
7.
Which communication medium generally uses pulses of light rather than electrical
signals to transmit information?
A. Coaxial cable
B. Fiber-optic cable
C. Category-rated copper cable
D. Twisted-pair telephone wire
Answer: B
Rationale: Fiber-optic systems transmit information using light through optical
fibers, providing high bandwidth and immunity to electromagnetic interference.
