1. A telecommunications technician in Maryland is primarily responsible
for which of the following core functions within modern
communication infrastructure systems?
A. Designing enterprise financial databases and accounting software
systems
B. Installing, configuring, maintaining, and troubleshooting voice, data,
and video communication systems across wired and wireless networks
C. Performing structural engineering calculations for building load-
bearing frameworks
D. Managing broadcast content creation for media production
companies
Answer: B
Rationale: Telecommunications technicians focus on the deployment,
maintenance, and troubleshooting of communication systems,
including voice, data, and video networks, ensuring reliable
connectivity across wired and wireless infrastructures.
2. Which of the following best describes the primary purpose of
structured cabling systems used in telecommunications installations?
A. To increase electrical voltage capacity for industrial machinery
, operations
B. To provide a standardized and organized infrastructure for
transmitting voice, data, and video signals efficiently and reliably
C. To eliminate the need for network switches and routers in
enterprise environments
D. To convert analog electrical signals directly into mechanical energy
for equipment control
Answer: B
Rationale: Structured cabling systems are designed to create a
standardized and scalable network infrastructure that supports
efficient transmission of communication signals while reducing
complexity and improving reliability.
3. In telecommunications networking, which device is primarily
responsible for directing data packets between different networks
based on IP addressing?
A. Hub
B. Switch
C. Router
D. Repeater
Answer: C
Rationale: A router operates by forwarding data packets between
different networks using logical IP addressing, enabling
communication across multiple network segments.
4. Which transmission medium is considered most suitable for high-
speed, long-distance telecommunications due to its immunity to
electromagnetic interference?
A. Twisted pair copper cable
B. Coaxial cable
C. Fiber optic cable
D. Aluminum wiring
Answer: C
Rationale: Fiber optic cables transmit data using light signals,
making them highly resistant to electromagnetic interference and
capable of supporting very high bandwidth over long distances.
, 5. What is the primary function of a network switch in a
telecommunications system?
A. To amplify weak electrical signals across long cable runs
B. To route internet traffic between different autonomous systems on
the internet backbone
C. To connect multiple devices within a local area network and
forward data based on MAC addresses
D. To convert digital signals into radio frequency transmissions for
wireless communication
Answer: C
Rationale: A network switch operates at the data link layer and
forwards data frames between devices within a local network using
MAC addresses to efficiently manage traffic flow.
6. Which standard is most commonly used to define Ethernet cable
wiring configurations and color coding?
A. IEEE 802.11
B. TIA/EIA-568
C. ISO 14001
D. FCC Part 97
Answer: B
Rationale: The TIA/EIA-568 standard defines structured cabling
practices, including wiring schemes and color codes used in Ethernet
installations.
7. What is the main function of a repeater in a telecommunications
network?
A. To store and analyze network traffic logs for cybersecurity purposes
B. To regenerate and amplify weakened signals to extend transmission
distance
C. To assign IP addresses dynamically to connected devices
D. To encrypt data packets before transmission over public networks
Answer: B
Rationale: A repeater strengthens or regenerates weakened signals,
allowing data transmission to travel further without degradation.
8. Which of the following best describes bandwidth in a
telecommunications context?
