Which element is typically described by Information Exchange Requirements?

• A. Technical interfaces
• B. Weather data
• C. Personnel rosters
• D. Building layouts

Answer: (A)

Information Exchange Requirements describe how systems connect and share data, focusing on the means of exchange rather than the content itself. They specify the technical interfaces—the points where systems meet, the data formats, communication protocols, transfer methods, and any timing or sequencing and security constraints. In other words, IERs define the exact way two systems interact so information can move reliably between them. While weather data, personnel rosters, or building layouts might be the actual information being exchanged, the IER is about the mechanism and rules of that exchange—the interface and its requirements. This is why technical interfaces are the element typically described by Information Exchange Requirements.
