Which type of barrier is most effective at stopping a vehicle traveling at 50 mph from breaching a perimeter?
Answer: Concrete Jersey barrier rated K12
A K12-rated concrete barrier is designed to stop a 15,000-lb vehicle traveling at 50 mph, meeting DoD anti-ram standards.
In a layered perimeter security model, which zone is defined as the area immediately surrounding the facility structure itself?
Answer: Inner perimeter zone
The inner perimeter zone is the area immediately surrounding the building envelope, representing the third layer in a concentric ring defense model.
What is the primary purpose of a mantrap (or airlock entry) in access control?
Answer: To prevent tailgating by allowing only one person through at a time
A mantrap uses two interlocked doors so the second cannot open until the first is secured, physically preventing tailgating or piggybacking.
A facility wants to deter intruders while maintaining an aesthetically pleasing exterior. Which perimeter solution best meets both goals?
Answer: Ornamental steel fencing with anti-climb spikes
Ornamental steel fencing with anti-climb spikes provides a strong physical deterrent while offering a professional, architecturally appropriate appearance.
Which access control card technology is most vulnerable to skimming attacks because it broadcasts data continuously?
Answer: 125 kHz proximity (Prox) card
125 kHz proximity cards continuously broadcast a fixed credential that can be captured by a reader held within a few inches, making them highly vulnerable to skimming.
During a site survey, a CSP notices that a door's electric strike fails open when power is lost. This configuration is referred to as:
Answer: Fail-safe
Fail-safe (also called fail-open) means the locking mechanism defaults to unlocked during a power failure, prioritizing life safety over security.
What does the term 'standoff distance' refer to in perimeter security planning?
Answer: The buffer zone between a potential threat and the protected asset
Standoff distance is the physical buffer maintained between a potential vehicle-borne or person-borne threat and the protected structure, reducing blast and ballistic impact.
