1. What is the primary purpose of a Building Automation System
(BAS)?
A. To generate electricity for buildings
B. To replace all electrical wiring
C. To monitor and control building systems automatically
D. To eliminate the need for maintenance staff
Rationale: BAS systems integrate HVAC, lighting, and security
controls to improve efficiency and automation.
2. Which system is most commonly controlled by a BAS?
A. Plumbing fixtures
B. HVAC systems
C. Structural framing
D. Elevator cables
Rationale: HVAC is the core subsystem managed by BAS for
temperature and air quality control.
,3. What does HVAC stand for?
A. Heating Voltage Air Control
B. Heating, Ventilation, and Air Conditioning
C. High Velocity Air Conditioning
D. Heat Volume Air Compression
Rationale: HVAC refers to systems regulating indoor environmental
comfort.
4. Which protocol is widely used in BAS communication?
A. HTTP

D. SMTP
Rationale: BACnet is a standard communication protocol for
building automation systems.
5. What device measures room temperature in a BAS?
A. Relay
B. Actuator
C. Sensor (Thermostat)
D. Damper
Rationale: Temperature sensors provide input data for BAS control
decisions.
6. What is the role of an actuator in BAS?
A. Measure humidity
, B. Display data
C. Physically move or control equipment
D. Store system logs
Rationale: Actuators convert control signals into mechanical
action.
