Which of the following is NOT a gateway type in Appian?

• A. AND
• B. XOR
• C. Event Based
• D. Complex

Answer: (C)

When modeling a process, gateways control how control flow splits or merges after a decision point, specifying how many branches run and under what conditions.

In Appian, the gateway types you can choose from include parallel (AND), exclusive (XOR), inclusive (OR), and a Complex gateway for more advanced routing. An event-based gateway, while common in BPMN, isn’t offered as a gateway type in Appian’s Process Modeler. If you need event-driven behavior, you’d implement it using event-related tasks or event listeners rather than a dedicated event-based gateway.

So, the option described as Event Based isn’t a gateway type supported by Appian, making it the correct choice for what is NOT a gateway type. The other options align with actual Appian gateway types.
