Question 1
What is the primary purpose of a structured cabling system?
A. To provide temporary network connections
B. To create a standardized telecommunications infrastructure
C. To replace all network equipment
D. To eliminate the need for testing
Correct Answer:
B. To create a standardized telecommunications infrastructure
Rationale:
Structured cabling provides an organized, standardized infrastructure that supports voice, data,
video, and other communication systems while allowing flexibility and future expansion.
Question 2
Which organization is most associated with telecommunications cabling standards used in North
America?
A. OSHA
B. TIA
C. IEEE only
D. FCC only
Correct Answer:
B. TIA
Rationale:
The Telecommunications Industry Association (TIA) develops widely used cabling standards,
including TIA-568 for commercial telecommunications cabling.
,Question 3
A horizontal cabling subsystem typically connects:
A. Work area outlets to telecommunications rooms
B. Building entrances to outside plants
C. Data centers to internet providers only
D. Electrical panels to equipment racks
Correct Answer:
A. Work area outlets to telecommunications rooms
Rationale:
Horizontal cabling runs from the telecommunications room (TR) to work area outlets and usually
includes permanent links, patch panels, and connecting hardware.
Question 4
Which cable category supports 10 Gigabit Ethernet over longer distances than Category 6?
A. Category 3
B. Category 5e
C. Category 6A
D. Category 6 only
Correct Answer:
C. Category 6A
Rationale:
Category 6A is designed to support 10GBASE-T Ethernet up to the full 100-meter channel
distance.
Question 5
What is the maximum permanent link length for horizontal cabling?
A. 50 meters
B. 75 meters
C. 90 meters
D. 120 meters
,Correct Answer:
C. 90 meters
Rationale:
The permanent link portion of horizontal cabling is typically limited to 90 meters, with
additional allowance for patch cords creating a 100-meter channel.
Question 6
Which copper conductor termination method is commonly used for Ethernet patch panels?
A. Splicing
B. Punch-down termination
C. Soldering
D. Twisting conductors together
Correct Answer:
B. Punch-down termination
Rationale:
Punch-down blocks and IDC (insulation displacement connection) technology are commonly
used for terminating twisted-pair copper cabling.
Question 7
What is the main purpose of twisting copper conductors in twisted-pair cable?
A. Increase cable weight
B. Reduce electromagnetic interference and crosstalk
C. Improve physical appearance
D. Increase cable diameter
Correct Answer:
B. Reduce electromagnetic interference and crosstalk
Rationale:
Twisting pairs helps cancel electromagnetic interference and reduces unwanted signal coupling
between pairs.
Question 8
, Which connector is commonly used with twisted-pair Ethernet cabling?
A. SC
B. LC
C. 8P8C modular connector
D. BNC
Correct Answer:
C. 8P8C modular connector
Rationale:
Ethernet twisted-pair cabling commonly uses 8P8C modular connectors, often incorrectly
referred to as RJ-45 connectors.
Question 9
What does NEXT measure in copper cable testing?
A. Signal loss caused by cable length
B. Crosstalk from one pair to another at the transmitting end
C. Fiber light loss
D. Ground resistance
Correct Answer:
B. Crosstalk from one pair to another at the transmitting end
Rationale:
Near-End Crosstalk (NEXT) measures unwanted signal interference between wire pairs near the
transmitter.
Question 10
Which instrument is used to certify copper cabling performance?
A. Tone generator only
B. Cable certification tester
C. Optical power meter only
D. Multimeter only
Correct Answer:
B. Cable certification tester
