Which of the following gateway types used in Appian's Process Modeler is matched incorrectly with its description?

The Event-Based Gateway is correctly defined as one that directs the flow of the process based on an event occurrence; however, it does not connect one incoming path with a single outgoing path. Instead, it functions by waiting for an event to occur and then directing workflow along one of the defined paths when the event is triggered. This gateway type typically provides multiple outgoing paths that are contingent upon different events.

The other types of gateways are accurately matched with their descriptions. The AND Gateway correctly directs all incoming workflows to every possible outgoing path, meaning that all paths are executed. The Complex Gateway allows for sophisticated control over flow by selectively accepting or restricting paths based on specific rules it evaluates. The OR Gateway allows workflow to proceed through one or more outgoing paths depending on defined conditions. Each of these descriptions fits their respective gateway types accurately.
