TPS Access Control & Perimeter Security 3 — Questions and Answers
Question 1: What is the purpose of a 'clear zone' around a perimeter fence?
- To provide a designated smoking area for employees
- To eliminate concealment and provide an unobstructed view for detection of intruders (Correct answer)
- To mark fire evacuation routes
- To allow landscaping and beautification
Correct answer: To eliminate concealment and provide an unobstructed view for detection of intruders
A clear zone removes vegetation, debris, and objects near the perimeter fence that could conceal intruders or provide a climbing aid.
Question 2: Which credential type is MOST resistant to duplication or forgery in an electronic access control system?
- Magnetic stripe card
- PIN code
- Biometric identifier (fingerprint or retinal scan) (Correct answer)
- Photo ID badge
Correct answer: Biometric identifier (fingerprint or retinal scan)
Biometric identifiers are unique to each individual and cannot be shared, lost, or easily duplicated like cards or PINs.
Question 3: A security officer notices an individual photographing the facility's access control panel. The BEST immediate response is to:
- Ignore it as it is not illegal to take photos
- Approach, identify yourself, ask for the person's name and purpose, and report the activity (Correct answer)
- Physically restrain the individual
- Call law enforcement before making contact
Correct answer: Approach, identify yourself, ask for the person's name and purpose, and report the activity
Security officers should contact and question suspicious individuals, document the incident, and report to supervisors while avoiding use of force unless legally justified.
Question 4: What does 'defense in depth' mean in perimeter security?
- Installing deep underground sensors
- Using multiple overlapping layers of security controls to slow and detect intruders (Correct answer)
- Deploying armed guards as the primary security measure
- Focusing all security resources at the main entrance
Correct answer: Using multiple overlapping layers of security controls to slow and detect intruders
Defense in depth uses multiple concentric security layers so that if one layer is breached, additional controls remain to detect or delay the intruder.
Question 5: Which lighting type is BEST suited for illuminating a large perimeter area at low cost?
- Strobe lighting
- Quartz lighting
- Floodlighting (Correct answer)
- Infrared-only lighting
Correct answer: Floodlighting
Floodlights produce broad, high-intensity illumination over large areas and are a standard choice for perimeter security lighting.
Question 6: An access control log shows an employee badging into a restricted server room at 2:00 AM, outside their normal work hours. This is an example of:
- Normal operations that should be ignored
- An anomaly that warrants investigation (Correct answer)
- A system malfunction requiring maintenance
- An authorized override that requires no action
Correct answer: An anomaly that warrants investigation
Unusual access patterns — such as off-hours entry to sensitive areas — are anomalies that security teams must investigate to rule out insider threat or compromise.
Question 7: Under Texas law, a security officer who detains someone must do which of the following?
- Hold the individual indefinitely until police arrive
- Use only the force necessary, notify law enforcement promptly, and release if no legal basis exists (Correct answer)
- Immediately transport the individual to a police station
- Conduct a full search of the individual's belongings
Correct answer: Use only the force necessary, notify law enforcement promptly, and release if no legal basis exists
Texas law limits security officers to reasonable, necessary force during detention and requires prompt notification of law enforcement; prolonged detention without cause is unlawful.
