CSC Security System Design & Implementation 2 — Questions and Answers
Question 1: Which design principle ensures that a security breach in one zone does not automatically compromise adjacent zones?
- Defense in depth
- Segmentation (Correct answer)
- Least privilege
- Fail-safe defaults
Correct answer: Segmentation
Segmentation isolates zones so that a compromise in one segment does not propagate to others.
Question 2: A client wants a door access control system that logs every entry attempt. Which component is MOST critical for forensic investigation?
- Electric strike plate
- Audit trail with timestamps (Correct answer)
- Magnetic door holder
- Motion sensor
Correct answer: Audit trail with timestamps
An audit trail with timestamps provides the evidentiary record needed for post-incident forensic analysis.
Question 3: When designing a CCTV system for a parking garage, what is the primary factor determining camera spacing?
- Brand of camera
- Field of view and resolution requirements (Correct answer)
- Cable length limits
- Color vs. monochrome setting
Correct answer: Field of view and resolution requirements
Camera spacing must be determined by field of view and resolution to ensure adequate coverage without blind spots.
Question 4: Which intrusion detection topology places sensors on every possible path an intruder might take to reach a protected asset?
- Perimeter detection (Correct answer)
- Interior volumetric detection
- Point protection
- Trap protection
Correct answer: Perimeter detection
Perimeter detection creates a boundary layer that triggers on the earliest possible intrusion attempt before the interior is reached.
Question 5: A security consultant recommends a dual-technology motion detector in a room with large windows. What threat does this address?
- Electrical interference
- False alarms from sunlight or HVAC air movement (Correct answer)
- Camera blind spots
- Unauthorized data access
Correct answer: False alarms from sunlight or HVAC air movement
Dual-technology detectors require two sensing methods to trigger simultaneously, dramatically reducing false alarms caused by environmental factors.
Question 6: In electronic access control, what is the purpose of a 'request-to-exit' (REX) sensor?
- To lock a door from the outside
- To allow free egress without triggering an alarm (Correct answer)
- To log visitor entry data
- To activate CCTV on door open
Correct answer: To allow free egress without triggering an alarm
A REX sensor detects outbound movement and shunts the door alarm circuit so a legitimate exit does not generate an alert.
Question 7: A hospital security design must allow rapid evacuation during a fire while maintaining access control. Which feature addresses this conflict?
- Fail-secure locking on all doors
- Fail-safe (fail-open) locking on egress doors tied to fire alarm (Correct answer)
- Biometric-only access
- Manual key override only
Correct answer: Fail-safe (fail-open) locking on egress doors tied to fire alarm
Fail-safe locks release upon fire alarm activation, satisfying life-safety egress requirements while normally maintaining access control.
