What is the difference between a 'patrol by exception' and a full patrol?

• A. They are the same
• B. Patrol by exception focuses on responding to incidents
• C. Patrol by exception covers all zones
• D. Full patrol is only during emergencies

Answer: (B)

The main idea tested here is how patrol approaches differ in terms of when action is taken. Patrol by exception is an incident-driven approach: guards monitor for alarms or anomalies and only intervene when something requires attention. Routine checks are minimized or guided by events, so resources are focused on responding to incidents rather than sweeping every area on a fixed schedule. A full patrol, on the other hand, is a proactive, comprehensive check of all zones on a regular schedule to maintain visibility and deterrence, regardless of whether an alarm has sounded. So, patrol by exception is best described as focusing on responding to incidents, not patrolling every area by default. The other statements don’t fit: they either imply all zones are covered by patrols in every case or mischaracterize when full patrols occur (not just during emergencies).
