1. The primary purpose of cable termination is to
A. improve the aesthetic look of the installation
B. ensure proper electrical connection
C. test the cable performance
D. reduce cable length
B. ensure proper electrical connection
Rationale: Proper termination ensures that the conductors make
solid contact with the intended connector to transmit signals
correctly.
2. Which of the following cable types is most commonly used for
horizontal network cabling?
A. Coaxial cable
B. Fiber optic cable
, C. Unshielded Twisted Pair (UTP)
D. Shielded Twisted Pair (STP)
C. Unshielded Twisted Pair (UTP)
Rationale: UTP cables like Cat5e and Cat6 are widely used for
horizontal network runs due to cost and performance.
3. What does the acronym ANSI stand for?
A. American National Standards Institute
B. Association of Network Standards International
C. American Network Systems Institute
D. Advanced National Standards Institute
A. American National Standards Institute
Rationale: ANSI coordinates voluntary standards in the U.S. across
multiple industries.
4. The maximum allowable pulling tension for a standard Cat5e cable is
typically:
A. 10 lbs
B. 25 lbs
C. 50 lbs
D. 75 lbs
B. 25 lbs
Rationale: Exceeding pulling tension can stretch and damage the
conductor pairs, affecting performance.
,5. Plenum-rated cable is required in which area?
A. Outdoor ducting
B. Under raised floors
C. Air handling spaces
D. In-wall vertical runs
C. Air handling spaces
Rationale: Plenum spaces circulate air for HVAC and require low-
smoke, fire-resistant cable.
6. What color is typically used for grounding conductors?
A. Black
B. Green
C. Red
D. Blue
B. Green
Rationale: Green indicates grounding to help ensure safety and
identification.
7. The purpose of a patch panel in a structured cabling system is to:
A. Boost signal strength
B. Provide a central point for cable termination
C. Store excess cable
D. Serve as a power distribution point
B. Provide a central point for cable termination
, Rationale: Patch panels organize cable terminations and facilitate
connections to active equipment.
8. A 110 termination block is used for terminating:
A. Coax cable
B. Fiber cable
C. Twisted pair cable
D. Power cable
C. Twisted pair cable
Rationale: 110 blocks are designed for UTP/STP twisted pair
termination.
9. The standard connector used on UTP network cable is:
A. RJ11
B. RJ45
C. SC
D. ST
B. RJ45
Rationale: RJ45 is the 8-position connector used for Ethernet twisted
pair.
10. What does TIA stand for?
A. Telecommunications Industry Association
B. Technical Installation Association
C. Technology Infrastructure Alliance
D. Telephony International Alliance
