PSP Perimeter Security and Physical Barriers 3

Question 1

Which perimeter intrusion detection system (PIDS) technology is MOST susceptible to nuisance alarms caused by wind, animals, and debris?

Accepted Answer

Buried seismic/vibration sensor cable

Answer

Microwave beam sensor

Answer

Ported coaxial leaky cable

Answer

Taut-wire fence sensor

Question 2

What is the primary security benefit of constructing a facility with a 'setback' from the property line in addition to a perimeter fence?

Accepted Answer

It provides depth-of-defense by creating multiple security layers with detection time between them

Answer

It reduces property taxes for the facility owner

Answer

It satisfies local building code requirements for fire access lanes

Answer

It reduces the cost of perimeter lighting installation

Question 3

According to ASTM standards, what does an 'F2656 M50 P1' anti-ram barrier rating indicate?

Accepted Answer

The barrier stopped a 5,000 kg vehicle at 80 km/h with less than 1 meter of penetration

Answer

The barrier is rated for 50 mph with a P1 (positive) structural test result

Answer

The barrier stopped a 6,800 kg vehicle at 80 km/h with no penetration

Answer

The rating indicates bollard spacing of 50 cm with P1 profile height

Question 4

A perimeter fence line must pass through a low-lying area prone to flooding. What is the BEST security solution to maintain perimeter integrity during flood events?

Accepted Answer

Install a flood gate or flap gate designed to allow water flow while deterring human intrusion

Answer

Install a concrete barrier instead of fence in the flood zone

Answer

Use underwater ground sensors connected to the alarm system

Answer

Raise the fence height to 12 feet in the flood-prone section

Question 5

What is the recommended maximum spacing between fence posts for a standard 7-foot chain-link security fence to maintain structural integrity under attack?

Accepted Answer

10 feet (3m)

Answer

6 feet (1.8m)

Answer

12 feet (3.6m)

Answer

16 feet (4.8m)

Question 6

In layered physical security design, what term describes the space between the outer perimeter fence and an inner security fence around the most sensitive areas?

Accepted Answer

No-man's land / controlled zone

Answer

Buffer zone

Answer

Dead zone

Answer

Annular space
