Question 1
Which type of cable is most commonly used for Ethernet horizontal
cabling in modern commercial data networks?
A. RG-6 coaxial cable
B. Category-rated twisted-pair cable
C. Speaker wire
D. Thermostat cable
Answer: B. Category-rated twisted-pair cable
Rationale: Category-rated twisted-pair cable, such as Cat 5e, Cat 6, and
Cat 6A, is specifically designed for structured Ethernet cabling. Its
twisted conductors help reduce electromagnetic interference and
crosstalk while supporting specified data rates.
,Question 2
What is the primary purpose of a telecommunications grounding and
bonding system?
A. Increase network bandwidth
B. Reduce cable attenuation
C. Provide a path for fault and transient currents and establish an
equipotential system
D. Increase telephone signal strength
Answer: C. Provide a path for fault and transient currents and
establish an equipotential system
Rationale: Telecommunications bonding and grounding help protect
personnel and equipment by providing appropriate paths for fault
currents, lightning-related transients, and other unwanted electrical
energy. Proper bonding also helps minimize potential differences
between metallic components.
Question 3
Which connector is commonly associated with twisted-pair Ethernet
patch cables?
,A. RJ-45 style modular connector
B. F-type connector
C. BNC connector
D. ST fiber connector
Answer: A. RJ-45 style modular connector
Rationale: Ethernet twisted-pair patch cords commonly use an 8-
position modular connector often referred to as RJ-45. F-type
connectors are generally associated with coaxial cable, while ST is a
fiber-optic connector style.
Question 4
What is the primary function of a patch panel in a structured cabling
system?
A. Convert AC power to DC power
B. Provide an organized termination and cross-connection point for
cables
C. Amplify every Ethernet signal
D. Replace network switches
Answer: B. Provide an organized termination and cross-connection
point for cables
, Rationale: A patch panel provides a fixed termination point for
horizontal or backbone cabling and allows equipment connections to be
made using patch cords. This makes moves, adds, and changes easier to
manage and reduces stress on permanent cabling.
Question 5
What does the term "backbone cabling" generally describe?
A. Cabling connecting telecommunications rooms and other major
distribution points
B. Only cables inside individual computers
C. Temporary extension cords
D. Cables used exclusively for security cameras
Answer: A. Cabling connecting telecommunications rooms and other
major distribution points
Rationale: Backbone cabling interconnects telecommunications rooms,
equipment rooms, entrance facilities, and other distribution locations. It
forms the primary pathway through which telecommunications services
are distributed throughout a building or campus.
