Question
A company has decided to relocate and the security manager has been tasked to perform a site survey of the new location to help in the design of the physical infrastructure. The current location has video surveillance throughout the building and entryways. The following requirements must be met:
- Able to log entry of all employees in and out of specific areas
- Access control into and out of all sensitive areas
- Tailgating prevention
Which of the following would MOST likely be implemented to meet the above requirements and provide a secure solution? (Select TWO).
Options
- ADiscretionary Access control
- BMan trap
- CVisitor logs
- DProximity readers
- EMotion detection sensors

Why each option
A man trap prevents tailgating into sensitive areas, and proximity readers log and control individual employee access, together satisfying all three stated physical security requirements.
Discretionary Access Control (DAC) is a logical data access model where owners grant permissions to objects and does not address physical entry, tailgating, or door access.
A man trap (access control vestibule) is a physical security control consisting of a small space with two interlocking doors, ensuring only one person can pass through at a time, which directly prevents tailgating and enforces access control into sensitive areas.
Visitor logs record who has visited but rely on manual entry, do not enforce access control, and do not prevent tailgating.
Proximity readers authenticate employees using RFID or smart cards, creating an electronic log of every entry and exit event and enforcing access control by only releasing the door lock for authorized credentials.
Motion detection sensors detect movement and can trigger alerts or cameras but do not control who passes through a door or prevent tailgating.
