CompTIA Security+ SY0-701 Practice Question

Bollards are designed to prevent vehicle intrusions into secure areas. They are short vertical posts that can be installed outside buildings or around perimeters to create barriers against vehicles. While fencing can also deter vehicles and unauthorized individuals, it is a wider perimeter security measure, not specifically engineered like bollards to withstand vehicle impacts. Security guards provide surveillance and response but are not physical barriers to vehicles. Access badges are a form of identification and access control but do not directly prevent vehicles from entering a secure location.
