Which gateway is used to model a parallel split where multiple paths can execute concurrently?

• A. Or gateway
• B. And gateway
• C. Event-based gateway
• D. Complex gateway

Answer: (B)

The concept being tested is how to model concurrent execution in a process using gateways. For a parallel split where several paths run at the same time, you use the And gateway. It creates multiple active paths from that point, all proceeding in parallel as soon as the process reaches the gateway. This is different from other gateways: the Or gateway represents a decision where only one path (or a limited subset) is taken based on conditions, the Event-based gateway waits for a specific event to occur and then follows the matching path, and the Complex gateway handles more intricate routing logic. An And gateway is the standard way to express true parallelism in the workflow.
