WSO-CSSD DOMAIN-BASED PRACTICE QUESTIONS
AND RATIONALES (UNOFFICIAL STUDY AID)
Representative Practice Questions (40)
Domain 1: Security
1. CPTED primarily aims to: A) Increase guard patrols B) Reduce
criminal opportunity through environmental design C) Install
more cameras D) Shorten response times
Answer: B. CPTED modifies the physical environment to
reduce crime opportunity.
2. The four principles of physical protection are: A) Deter,
Detect, Delay, Respond B) Plan, Prevent, Protect, Pursue C)
Assess, Approve, Apply, Audit D) Screen, Search, Seal, Secure
Answer: A. These describe layered physical security
functions.
3. Anti-passback prevents: A) Tailgating at a door B) One
credential being used twice in the same direction C) Lost
badge reporting D) Camera recording
Answer: B. It enforces one-in, one-out sequencing per
credential.
4. Which credential type is most resistant to cloning? A)
Magnetic stripe B) Proximity card C) Mutual-authentication
smart card D) Paper badge
Answer: C. Mutual authentication smart cards are far harder
to clone.
, 5. Removing hiding places near a loading dock is an example
of: A) Target hardening B) CPTED C) Access control D) Loss
prevention audit
Answer: B. Removing concealment is an environmental
design strategy.
6. Perimeter lighting's main security purpose is to: A) Reduce
cost B) Remove concealment and aid detection C) Satisfy fire
code D) Improve appearance
Answer: B. Lighting denies cover and supports detection.
7. Tailgating is best mitigated by: A) Signs only B) Physical
barriers such as turnstiles C) Longer passwords D) More
cameras
Answer: B. Physical barriers enforce one-person-at-a-time
entry.
Domain 2: Safety and Loss Control Science
8. Heinrich's Domino Theory holds that: A) Accidents are
random B) Accidents result from a chain of events C) Only
major injuries matter D) Near misses are irrelevant
Answer: B. Removing one link in the chain prevents the loss.
9. Heinrich's 300-30-1 ratio relates: A) Minor incidents to major
injuries B) Costs to budgets C) Guards to cameras D) Training
hours to incidents
Answer: A. It links minor incidents, injuries, and major
injuries.
10. Direct costs of an accident include: A) Lost productivity
B) Medical bills and repairs C) Morale loss D) Replacement
