QUESTION 1.
A defense contractor is renovating a facility that will process classified information.
Budget limitations require delaying installation of one planned security component.
Which decision best reflects a security-in-depth philosophy?
A. Eliminate the intrusion detection system because security guards conduct patrols.
B. Delay installation of decorative perimeter fencing while maintaining complementary
detection, delay, and response capabilities.
C. Remove access control readers and rely solely on employee badges.
D. Reduce security lighting because cameras provide visual coverage.
Correct Answer: B. Delay installation of decorative perimeter fencing while
maintaining complementary detection, delay, and response capabilities.
Explanation: Security-in-depth depends on multiple mutually supporting layers that
detect, delay, assess, and respond to threats. Decorative fencing generally contributes
less to the integrated protection strategy than essential electronic and procedural
controls. The remaining options remove critical security layers and significantly
increase vulnerability.
────────────────────────────────────────
QUESTION 2.
A physical security specialist determines that an adversary can penetrate a facility in
less time than the protective force requires to respond. Which corrective action most
directly addresses the identified deficiency?
A. Increase visitor screening documentation.
B. Improve employee awareness training.
C. Increase delay measures so response time becomes effective before asset
compromise.
D. Reduce the number of alarm zones.
, Correct Answer: C. Increase delay measures so response time becomes effective
before asset compromise.
Explanation: Effective physical protection requires delay time to exceed adversary
task completion until responders can intervene. Additional barriers, reinforced doors,
or other delay measures strengthen overall system performance. The other options
do not directly resolve the timing imbalance between penetration and response.
────────────────────────────────────────
QUESTION 3.
During a vulnerability assessment, multiple threats are identified. Which factor should
receive the greatest consideration when prioritizing mitigation resources?
A. The age of the facility.
B. The likelihood of exploitation combined with operational consequences.
C. The number of employees assigned to the building.
D. The replacement cost of office furniture.
Correct Answer: B. The likelihood of exploitation combined with operational
consequences.
Explanation: Risk-based decision making prioritizes vulnerabilities according to both
the probability of exploitation and the severity of resulting consequences. This
approach enables efficient allocation of limited resources. The remaining factors may
influence planning but are not primary risk prioritization criteria.
────────────────────────────────────────
QUESTION 4.
A secure facility experiences repeated nuisance alarms from its intrusion detection
system during severe weather. What is the most appropriate long-term corrective
action?
A. Disable affected sensors whenever storms are forecast.
B. Ignore alarm activations occurring during bad weather.
C. Reduce monitoring sensitivity without documentation.
, D. Analyze alarm causes and optimize sensor selection, placement, and calibration
while preserving required detection performance.
Correct Answer: D. Analyze alarm causes and optimize sensor selection,
placement, and calibration while preserving required detection performance.
Explanation: Physical security systems should minimize nuisance alarms without
sacrificing reliable detection. Engineering analysis and proper system adjustment
provide sustainable improvements. Disabling or ignoring alarms creates
unacceptable security gaps.
────────────────────────────────────────
QUESTION 5.
Which situation represents the strongest justification for implementing multifactor
access control at a protected area?
A. The protected assets have exceptionally high mission impact if compromised.
B. The building has recently been repainted.
C. Employee parking capacity has increased.
D. Visitor traffic has decreased.
Correct Answer: A. The protected assets have exceptionally high mission impact
if compromised.
Explanation: Multifactor authentication provides stronger identity assurance and is
most appropriate where compromise would have severe operational or national
security consequences. Cosmetic facility changes and parking conditions do not
justify enhanced authentication requirements.
────────────────────────────────────────
QUESTION 6.
An organization plans to integrate video analytics with access control and intrusion
detection systems. What is the primary operational benefit of such integration?
A. Elimination of all false alarms.
B. Automated correlation of events that improves assessment and response
