Install bollards in front of the entrance
- B
Install a mantrap at the front door
- C
Add privacy window film to the glass panels
- D
Require smart cards for all employees
Show answer and explanation
Correct answer: A
Explanation
The best answer is to install bollards. In A+ Core 2 physical security topics, bollards are used to protect buildings and people from vehicle intrusion by creating a hardened barrier outside entrances or perimeter areas. This is a practical real-world control for storefronts, office entrances, and areas near sensitive facilities. By contrast, mantraps and smart cards are access-control measures for people, and privacy film addresses visibility rather than impact prevention. Security best practices emphasize selecting controls that directly address the identified risk; for vehicle-borne threats or accidental vehicle strikes, bollards are the appropriate preventive control.
- A. Correct.
Correct. Bollards are strong physical barriers placed outside buildings to prevent vehicles from reaching entrances, walkways, or other protected areas. In this scenario, the primary risk is vehicle impact against the building, so bollards are the most appropriate physical security control.
- B. Incorrect.
Incorrect. A mantrap controls pedestrian access by requiring a person to pass through two interlocking doors. It helps prevent tailgating and unauthorized entry, but it does not stop a vehicle from crashing into the building.
- C. Incorrect.
Incorrect. Privacy window film may reduce visibility into the building and can sometimes help with privacy or minor glass-related concerns, but it is not designed to stop a vehicle from entering the lobby. Choosing this option confuses visual privacy with vehicle-impact protection.
- D. Incorrect.
Incorrect. Smart cards are a logical and physical access control method for authenticating users at doors or systems. They help control who enters a facility, but they do not mitigate the threat of a vehicle striking the building.
