1. Which component in a structured cabling system is designed to
terminate horizontal cabling and provide connection to work area
outlets?
A. Backbone cabling
B. Horizontal cross-connect
C. Entrance facility
D. Main distribution frame
Rationale: The horizontal cross-connect is the point where horizontal
cabling terminates and connects to the work area outlets, providing
organized distribution.
2. What is the maximum allowable horizontal cable length in a typical
premises structured cabling system according to standards?
A. 150 meters
B. 120 meters
C. 90 meters
D. 60 meters
, Rationale: Standards specify a maximum horizontal cabling length of
90 meters to ensure signal integrity and performance.
3. In a structured cabling system, which cable type is most commonly
used for Gigabit Ethernet?
A. Coaxial
B. Category 6 UTP
C. Category 3
D. Single-mode fiber
Rationale: Category 6 UTP is widely used for Gigabit Ethernet due to
its bandwidth and performance characteristics.
4. What does UTP stand for in cabling terminology?
A. Universal Twisted Pair
B. Uniform Transmission Path
C. Unshielded Twisted Pair
D. Unified Telecommunications Path
Rationale: UTP stands for Unshielded Twisted Pair, a common cable
type in structured cabling.
5. Which organization publishes the ANSI/TIA-568 standards for
structured cabling?
A. IEEE
B. ISO
C. TIA
D. FCC
Rationale: The Telecommunications Industry Association (TIA)
publishes the ANSI/TIA-568 standards.
6. What color code is typically used for patch cords connecting to the
horizontal cross-connect?
A. Green
B. Red
, C. Blue
D. Yellow
Rationale: Blue is commonly used for patch cords connecting
horizontal cross-connects to reduce identification errors.
7. What test instrument is used to certify a copper cable installation for
performance standards?
A. Optical power meter
B. Multimeter
C. Cable certifier
D. Signal generator
Rationale: A cable certifier tests copper cabling against industry
performance standards.
8. Which type of fiber optic cable is typically used for long distance
backbone runs?
A. OM3
B. OM4
C. Single-mode fiber
D. Plenum multimode
Rationale: Single-mode fiber is preferred for long distance runs
because it supports higher bandwidth with less attenuation.
9. What is the purpose of a patch panel in structured cabling?
A. Amplify signals
B. Provide power to devices
C. Provide a centralized point for cable termination and management
D. Convert copper to fiber
Rationale: Patch panels centralize termination and management for
easier organization and troubleshooting.
10. Which fire safety rating is required for cable in plenum air
spaces?
