Call prioritization may be assisted by which system?

• A. GIS
• B. RMS
• C. 9-1-1
• D. CAD

Answer: (D)

Call prioritization is best supported by a system that centralizes incoming incidents, tracks urgency, and automatically routes the right units based on priority. This is what Computer-Aided Dispatch does. CAD monitors each call’s details, applies prioritization rules (for example, elevating life-threatening or time-sensitive incidents to the top), and dispatches available units accordingly. It also updates in real time as new information comes in, changing priorities if needed and providing clear status and ETA information to responders. While GIS offers mapping data, RMS stores records, and 9-1-1 is just the incoming call channel, none of those systems are built primarily to manage and prioritize dispatch and resource assignment the way CAD does.
