CPI CPI Physical Security & Access Control 1 — Questions and Answers
Question 1: Which type of lock is most commonly recommended for high-security access control in commercial inspections?
- Standard pin tumbler lock
- High-security deadbolt with anti-pick pins (Correct answer)
- Padlock with shackle
- Magnetic cabinet lock
Correct answer: High-security deadbolt with anti-pick pins
High-security deadbolts with anti-pick pins provide significantly greater resistance to forced and covert entry than standard locks.
Question 2: What is the primary purpose of a 'man-trap' or airlock entry system in a secure facility?
- Speed up employee entry
- Prevent tailgating and unauthorized access (Correct answer)
- Reduce energy costs
- Monitor HVAC performance
Correct answer: Prevent tailgating and unauthorized access
A man-trap ensures only one person enters at a time by requiring credential verification before the second door opens, preventing tailgating.
Question 3: During a security inspection, a CPI finds that emergency exit doors lack proper hardware. Which standard governs life safety exit requirements?
- OSHA 1910.37
- NFPA 72
- NFPA 101 (Life Safety Code) (Correct answer)
- IBC Chapter 10
Correct answer: NFPA 101 (Life Safety Code)
NFPA 101, the Life Safety Code, is the primary standard governing means of egress, exit hardware, and emergency exit requirements.
Question 4: What does 'piggybacking' mean in the context of physical security access control?
- Installing two cameras on one mount
- An authorized person allowing an unauthorized person to follow them through a secured door (Correct answer)
- Using two key cards simultaneously
- Bypassing a security alarm remotely
Correct answer: An authorized person allowing an unauthorized person to follow them through a secured door
Piggybacking (or tailgating) is when an unauthorized individual follows closely behind an authorized person through a secured entry point.
Question 5: A CPI inspecting a facility notices CCTV cameras have significant blind spots near entry points. What is the best corrective recommendation?
- Add motion-sensing lighting only
- Reposition or add cameras to achieve overlapping coverage of all entry points (Correct answer)
- Install mirrors in the blind spots
- Post security guards at every blind spot permanently
Correct answer: Reposition or add cameras to achieve overlapping coverage of all entry points
Overlapping camera coverage eliminates blind spots and ensures continuous visual monitoring of all critical entry and exit points.
Question 6: Which access control credential type is considered most vulnerable to cloning attacks?
- Smart card with PKI encryption
- Biometric fingerprint scanner
- Low-frequency 125 kHz proximity card (HID Prox) (Correct answer)
- PIN with two-factor authentication
Correct answer: Low-frequency 125 kHz proximity card (HID Prox)
Legacy 125 kHz proximity cards transmit unencrypted credentials and can be cloned easily with readily available RFID readers.
