CPI CPI Physical Security & Access Control 2 — Questions and Answers
Question 1: What is the 'defense in depth' principle as applied to physical security inspections?
- Using only one very strong security measure
- Layering multiple overlapping security controls so failure of one does not compromise the whole system (Correct answer)
- Focusing all security resources on the perimeter
- Conducting security checks only at entry points
Correct answer: Layering multiple overlapping security controls so failure of one does not compromise the whole system
Defense in depth uses multiple layers of security controls so that if one layer is breached, subsequent layers continue to protect assets.
Question 2: During a physical security assessment, a CPI evaluates fence height. What minimum height does most commercial security guidance recommend for a perimeter security fence?
- 4 feet
- 6 feet
- 8 feet (Correct answer)
- 10 feet
Correct answer: 8 feet
Most commercial security standards recommend a minimum 8-foot perimeter fence to deter and delay unauthorized intrusion.
Question 3: Which lighting type is most effective for perimeter security in outdoor environments?
- Decorative low-wattage pathway lights
- High-pressure sodium or LED floodlights with motion activation (Correct answer)
- Interior fluorescent lighting
- Strobe lights
Correct answer: High-pressure sodium or LED floodlights with motion activation
High-pressure sodium or LED floodlights with motion activation provide bright, energy-efficient illumination that deters intruders and aids camera capture.
Question 4: A CPI identifies that a facility's visitor log is paper-based and uncontrolled. What is the most significant security risk?
- Paper logs are too expensive
- Lack of accurate accountability and inability to quickly verify who is currently on-site in an emergency (Correct answer)
- Visitors cannot sign in quickly
- Paper logs cannot be integrated with email
Correct answer: Lack of accurate accountability and inability to quickly verify who is currently on-site in an emergency
An uncontrolled paper log cannot reliably confirm who is on-site, creating accountability gaps and emergency muster failures.
Question 5: What is 'CPTED' and how does it relate to physical security inspections?
- Certified Physical Training and Enforcement Doctrine — a use-of-force standard
- Crime Prevention Through Environmental Design — using design and landscaping to reduce crime opportunities (Correct answer)
- Critical Physical Threat Emergency Detection — an alarm protocol
- Computer-based Physical Threat Evaluation and Detection system
Correct answer: Crime Prevention Through Environmental Design — using design and landscaping to reduce crime opportunities
CPTED is a security philosophy that uses natural surveillance, territorial reinforcement, and environmental design to reduce opportunities for crime.
Question 6: Which of the following is a key indicator of forced entry that a CPI should document during a post-incident inspection?
- A locked door with no visible damage
- Tool marks, splintering around door frames, or bent hardware indicating prying or forcing (Correct answer)
- Normal paint wear on door surfaces
- Manufacturer labels on lock bodies
Correct answer: Tool marks, splintering around door frames, or bent hardware indicating prying or forcing
Tool marks, frame splintering, and bent hardware are physical evidence of forced entry attempts that must be carefully documented.
