1. What is the primary purpose of an access control system?
A. To increase building lighting
B. To regulate and monitor entry to protected areas
C. To replace all fire alarm systems
D. To provide emergency electrical generation
Answer: B. To regulate and monitor entry to protected areas
Rationale: An access control system is designed to control who can
enter or exit a protected area and under what conditions. It commonly

controlled door after receiving credential information?
,A. Door closer
B. Access control panel/controller
C. Exit sign
D. Mechanical hinge
Answer: B. Access control panel/controller
Rationale: The access control controller processes credential
information and compares it with programmed authorization data.
When access is permitted, the controller activates the appropriate
locking device or relay.
3. Which credential is commonly presented to a proximity or smart-
card reader?
A. Hydraulic key
B. Radio-frequency identification card
C. Pneumatic switch
D. Mechanical thermostat
Answer: B. Radio-frequency identification card
Rationale: RFID credentials communicate wirelessly with compatible
readers. Depending on the system, credentials may contain
identification data that the reader transmits to the access control
controller for authorization.
, 4. What is the primary function of a request-to-exit device?
A. To prevent all occupants from leaving

A. To identify or authenticate a user
B. To provide mechanical ventilation
C. To cool an electrical panel
D. To regulate water pressure
Answer: A. To identify or authenticate a user
Rationale: Credentials such as cards, fobs, mobile credentials, or
biometric identifiers provide information that allows the system to
determine whether a person is authorized for a particular access
point.
7. Which locking device is specifically designed to secure a door
electronically by using a magnetic field?
A. Mortise cylinder
