Which system is an example of DRMNS?

• A. Public address
• B. Phone tree
• C. SMS alerts
• D. Reverse 9-1-1

Answer: (D)

DRMNS is about delivering urgent alerts to a broad public quickly through an automated, area-wide notification system. Reverse 9-1-1 fits this best because it automatically dials residents and businesses in a defined geographic area to deliver warnings and instructions, reaching a large audience without requiring people to relay messages or be in a specific place. Public address is limited to a single location, a phone tree depends on manual relays, and while SMS alerts can reach many people, the automated, area-wide reach of Reverse 9-1-1 is the clearest example of DRMNS.
