A barrier system is any obstacle provided that causes direct impact on what aspects to circumvent the obstacle?

• A. Increased energy usage
• B. Faster exit from the site
• C. Less need for lighting
• D. Direct impact on the speed, time, and tools necessary to circumvent the obstacle

Answer: (D)

The main idea here is that barrier systems are meant to slow and complicate a breach by affecting how quickly someone can get past it, how long the attempt takes, and what tools they must bring. A well-designed barrier changes the attacker’s operational parameters, not the environment’s energy use or lighting. So it’s about speed, time, and the required tools to circumvent the obstacle. For example, a sturdy gate or bollards might slow a vehicle, lengthen the time needed to breach, and force the use of specialized equipment. That aligns with the purpose of barriers to create delay and increase the effort needed to penetrate protected space. The other options don’t capture this impact on bypassing the obstacle.
