Guide
1. What is the primary purpose of a telecommunications cabling installation
standard?
A. To increase cable length
B. To establish consistent installation and performance practices
C. To eliminate the need for testing
D. To reduce the number of cables required
Answer: To establish consistent installation and performance practices
Rationale: Standards provide consistent requirements for design, installation,
performance, safety, and administration of telecommunications cabling
systems.
2. Which tool is commonly used to terminate 110-style telecommunications
cable?
A. Torque wrench
B. Punch-down tool
C. Cable cutter
D. Fish tape
Answer: Punch-down tool
,Rationale: A punch-down tool seats individual conductors into insulation
displacement connection (IDC) terminals such as 110 blocks and compatible
jacks.
3. What is the main purpose of a cable jacket?
A. Increase signal speed
B. Protect the conductors from physical and environmental damage
C. Increase conductor resistance
D. Replace grounding
Answer: Protect the conductors from physical and environmental damage
Rationale: The jacket provides mechanical protection and, depending on cable
construction, may also provide protection against environmental conditions.
4. Which cable type commonly contains four twisted pairs?
A. Category-rated balanced twisted-pair cable
B. Coaxial cable
C. Fiber-optic cable
D. Twinaxial cable
Answer: Category-rated balanced twisted-pair cable
Rationale: Common horizontal balanced twisted-pair telecommunications cables
contain four twisted pairs, or eight individual conductors.
5. Why are conductors twisted together in a balanced twisted-pair cable?
A. To increase cable diameter
B. To reduce electromagnetic interference and crosstalk
C. To make termination impossible
D. To eliminate attenuation
Answer: To reduce electromagnetic interference and crosstalk
,Rationale: Twisting helps maintain balance and reduces susceptibility to external
interference and coupling between pairs.
6. What should an installer do before beginning work in an unfamiliar
telecommunications space?
A. Immediately start pulling cable
B. Review drawings, work requirements, safety procedures, and site conditions
C. Remove all existing cables
D. Disconnect all equipment
Answer: Review drawings, work requirements, safety procedures, and site
conditions
Rationale: Pre-installation planning helps identify hazards, pathways, existing
systems, work restrictions, and installation requirements.
7. What is the purpose of cable pathway systems?
A. To generate electrical power
B. To provide an organized route and physical support for cables
C. To amplify network signals
D. To terminate fiber
Answer: To provide an organized route and physical support for cables
Rationale: Cable trays, conduits, raceways, and other pathways protect and
support telecommunications cabling.
8. Which condition should be avoided when installing copper twisted-pair
cable?
A. Proper support
B. Excessive pulling tension
C. Correct bend radius
D. Proper labeling
Answer: Excessive pulling tension
, Rationale: Excessive pulling tension can deform cable geometry and negatively
affect transmission performance.
9. What does bend radius refer to?
A. Cable weight
B. The minimum radius to which a cable should be bent
C. Cable length
D. Conductor diameter only
Answer: The minimum radius to which a cable should be bent
Rationale: Maintaining the manufacturer's specified bend radius helps prevent
damage and performance degradation.
10.Which document typically identifies cable routes and outlet locations?
A. Floor plan or telecommunications drawing
B. Payroll report
C. Safety Data Sheet only
D. Purchase order only
Answer: Floor plan or telecommunications drawing
Rationale: Telecommunications drawings show pathways, outlets, equipment
spaces, and other installation information needed by installers.
11.What is the purpose of cable labeling?
A. To increase bandwidth
B. To identify cables and facilitate administration and troubleshooting
C. To reduce cable diameter
D. To replace testing
Answer: To identify cables and facilitate administration and troubleshooting
Rationale: Consistent labeling allows technicians to trace and identify cables
efficiently during installation, testing, maintenance, and troubleshooting.
