Which gateway type is matched incorrectly with its description?

• A. Event-based Gateway - Connects one incoming path with a single outgoing path based on the conditions set.
• B. And gateway - Directs all incoming workflows to all possible branches.
• C. Complex gateway - Allows you to selectively accept or restrict incoming paths and evaluate rules to determine outgoing paths.
• D. Or gateway - Directs incoming flows to one or more possible outgoing paths based on the conditions set.

Answer: (A)

The key idea here is how event-based gateways decide which path to take. An event-based gateway chooses its outgoing path based on events that occur, not by evaluating a fixed condition on each outgoing flow. It has one incoming path and multiple potential outgoing paths, each tied to a specific event or message, and it waits for the first event to happen to determine which path to follow. Describing it as connecting one incoming path with a single outgoing path “based on conditions” misrepresents how this gateway operates, since the choice depends on which event occurs rather than a single conditional check.

In contrast, the And (parallel) gateway creates or merges parallel flows, requiring all paths to be taken or completed. The Or (inclusive) gateway routes to one or more outgoing paths based on conditions, allowing multiple branches to be active. The Complex gateway handles more intricate routing rules that can combine events and conditions to determine outgoing paths.
