Which of the following is NOT one of the five essential Rescue 21 programs?

• A. Geographic display
• B. V4 Workstation
• C. Caller Manager
• D. Weather Monitor

Answer: (D)

The five essential Rescue 21 programs are the components that directly support the real-time communications and incident-management workflow. Geographic display provides a map view of assets and incident locations, giving responders a clear situational picture. V4 Workstation is the primary interface for handling radio traffic and coordinating communications across the network. Caller Manager organizes caller information and helps route and manage calls efficiently. Weather Monitor, while useful for tracking weather conditions that can influence operations, is not part of the core Rescue 21 program set because it delivers meteorological data rather than directly supporting the rescue communications workflow. So Weather Monitor is the finish line here: it isn’t one of the five essential Rescue 21 programs.
