North Dakota Security Guard Practice Exam

The correct answer is 10-33 because in the standard law enforcement 10-code system, 10-33 is the code that corresponds to "Emergency - all units stand by". The 10-code system is a set of codes that represent common phrases and terms used in law enforcement and emergency response. The number 33 is specifically designated for emergency situations requiring all units to stand by. This code is used to signal to all units that there is an emergency situation and they need to be ready for instructions. This allows for quick and clear communication, particularly in high-stress situations.
