1. What is the primary purpose of an electronic access control system?
A. To eliminate the need for physical security measures
B. To regulate and monitor access to protected areas
C. To replace all fire alarm systems
D. To provide unrestricted entry to all building occupants
Correct Answer: B. To regulate and monitor access to protected areas
Rationale: An electronic access control system determines who may
enter or exit a protected area and under what conditions. It uses
credentials, readers, controllers, and locking devices to enforce access
permissions. Depending on its configuration, it can also record events
,and generate alarms. It supplements rather than eliminates other
security measures.
2. Which component verifies the identity or credential presented by a
user at a controlled door?
A. Door closer
B. Power supply
C. Access control reader
D. Request-to-exit device
Correct Answer: C. Access control reader
Rationale: The access control reader captures credential information
from a card, fob, mobile device, or other supported credential. It
transmits that information to a controller or access control system for
authorization. A reader generally does not physically unlock the door
by itself; the controller determines whether access should be granted.
3. What is the principal function of an access control panel?
A. To mechanically secure the door
B. To process access decisions and control connected devices
C. To provide structural support for the door frame
D. To replace the building's electrical distribution panel
,Correct Answer: B. To process access decisions and control connected
devices
Rationale: An access control panel receives credential data and inputs
from connected devices, applies access rules, and commands outputs
such as electric locks or relays. Depending on the system architecture,
authorization decisions may be made locally or through a central
server. The panel is a central control component, not a mechanical
locking device.
4. Which credential technology commonly uses radio-frequency
communication between a card and a reader?
A. Mechanical key
B. Magnetic door holder
C. Proximity card
D. Door contact switch
Correct Answer: C. Proximity card
Rationale: A proximity card communicates with a compatible reader
using radio-frequency technology. Depending on the credential type,
communication may involve low-frequency or high-frequency
technologies. The reader captures the credential's identifying
information, which is then evaluated by the access control system.
, 5. What is the primary purpose of a door position switch in an access
control system?
A. To measure the voltage supplied to the lock
B. To detect whether a door is open or closed
C. To determine the identity of a cardholder
D. To release the door during a fire
Correct Answer: B. To detect whether a door is open or closed
Rationale: A door position switch, often implemented as a magnetic
contact, monitors the physical state of a door. The system can use this
information to identify a door left open, a forced-open condition, or
an unauthorized opening. It does not directly determine whether a
person is authorized to enter.
6. Which device is commonly used to allow an authorized person to exit
a secured room without presenting a credential?
A. Request-to-exit device
B. Card enrollment station
C. Credential printer
D. Network switch
Correct Answer: A. Request-to-exit device
