1. Which Massachusetts license classification most closely
corresponds to a technician performing regulated low-voltage
systems work, including communications, data, security, and related
systems?
A. Class A Master Electrician
B. Class B Journeyman Electrician
C. Class D Systems Technician
D. Class C Systems Contractor
The Class D Systems Technician license is the Massachusetts
classification associated with qualifying systems work performed by
technicians. Massachusetts identifies a specific Systems Technician
examination and establishes education and experience requirements for
that classification.
, 2. A Massachusetts Systems Technician candidate must complete how
many hours of Board-approved education before qualifying for the
examination?
A. 75 hours
B. 150 hours
C. 300 hours
D. 600 hours
Massachusetts requires 300 clock-hours of Board-approved education as
a prerequisite for the Systems Technician examination.
3. Which combination best represents the type of systems knowledge
expected of a telecommunications and data systems technician?
A. Plumbing, masonry, roofing, and excavation
B. Low-voltage circuits, communications wiring, grounding, testing, and
applicable electrical requirements
C. High-pressure steam systems and boilers
D. Structural steel welding and reinforcing
A systems technician must understand the electrical and
communications principles governing low-voltage installations,
including wiring, grounding, testing, and applicable code requirements.
4. What is the primary purpose of a telecommunications structured
cabling system?
A. To provide mechanical ventilation
B. To distribute natural gas
,C. To provide an organized infrastructure for transporting voice, data,
video, and other communications signals
D. To replace building electrical services
Structured cabling creates an organized and standardized infrastructure
capable of supporting multiple communications applications and
technologies.
5. Which cable type is generally most resistant to electromagnetic
interference?
A. Unshielded twisted-pair copper
B. Shielded twisted-pair copper
C. Coaxial cable
D. Optical fiber
Optical fiber transmits information using light rather than electrical
current, making it inherently resistant to electromagnetic interference.
6. What is the primary function of twisting conductors together in a
balanced copper communications cable?
A. Increase conductor voltage
B. Increase conductor resistance
C. Reduce the effects of external interference and crosstalk
D. Eliminate the need for grounding
The twisting pattern helps maintain balanced electromagnetic
characteristics and reduces interference and crosstalk between circuits.
, 7. Which connector is commonly associated with Ethernet twisted-pair
cabling?
A. F-type
B. BNC
C. 8P8C modular connector commonly called RJ-45
D. ST fiber connector
Ethernet copper cabling commonly terminates in an 8P8C modular
connector, widely referred to in the field as an RJ-45 connector.
8. What is the principal difference between single-mode and
multimode optical fiber?
A. Single-mode fiber uses copper conductors
B. Multimode fiber cannot transmit digital signals
C. Single-mode fiber has a much smaller core and is generally intended
for longer-distance transmission
D. Multimode fiber operates only with analog signals
Single-mode fiber has a smaller core that supports propagation of
essentially one mode of light, making it suitable for longer distances and
higher-bandwidth applications.
9. A technician measures excessive optical loss immediately after
installing a fiber connector. Which condition should be investigated
first?
A. Copper conductor resistance
B. AC line frequency
