1. Which of the following works describes the set of standards for
structured cabling systems?
A. TIA-942
B. TIA-568
C. IEEE 802.3
D. ISO/IEC 11801
The TIA-568 standard covers telecommunications cabling
specifications used in commercial buildings.
2. What is the maximum allowable DC resistance unbalance for balanced
twisted-pair cabling?
A. 2%
B. 3%
C. 5%
D. 10%
, Resistance unbalance limits help ensure consistent signal
performance across pairs.
3. Which fiber type has the largest core diameter?
A. Single-mode
B. Multimode
C. Plastic optical fiber
D. Graded-index cable
Multimode fiber uses a larger core diameter than single-mode,
allowing multiple light paths.
4. What does “plenum” refer to in cabling?
A. A type of cable jacket color
B. A measurement of bandwidth
C. A building space used for airflow
D. A grounding method
Plenum describes spaces used for air circulation that have strict fire
safety material requirements.
5. Which connector type is typically used on twisted-pair horizontal
cabling?
A. ST
B. SC
C. RJ-45
D. LC
, RJ-45 is the standard modular connector for twisted-pair Ethernet
cabling.
6. What is the purpose of a telecommunications room?
A. To store unused cable
B. To house cross-connects and equipment
C. To serve as a workspace for users
D. To measure signal loss
Telecommunications rooms centralize cross-connect hardware and
active equipment.
7. The abbreviation “UTP” stands for:
A. Universal Telephone Pair
B. Unshielded Twisted Power
C. Unshielded Twisted Pair
D. Unified Termination Port
UTP describes twisted pair cabling without additional shielding.
8. Which test instrument measures cable length and identifies faults by
sending pulses?
A. Tone generator
B. Power meter
C. OTDR
D. TDR
OTDR (Optical Time Domain Reflectometer) sends pulses through
fiber to locate issues and measure length.
, 9. What is the standard maximum horizontal cable length in a structured
cabling system?
A. 50 meters
B. 75 meters
C. 90 meters
D. 100 meters
90 meters is the maximum horizontal distance between the work
area and telecommunications room.
10. Which frequency category provides performance up to 250
MHz?
A. Category 3
B. Category 5e
C. Category 6
D. Category 8
Category 6 UTP supports up to 250 MHz frequencies.
11. Where is the equipment grounding conductor connected?
A. To the network equipment rack only
B. To the building grounding system
C. To each individual outlet
D. To cable shielding only
All grounding conductors must ultimately tie into the building’s
grounding system.
