Which gateway uses complex logic?

• A. Event-Based Gateway
• B. Complex Gateway
• C. Exclusive Gateway
• D. Inclusive Gateway

Answer: (B)

A Complex Gateway is used when the routing decision depends on a combination of conditions evaluated together, not on a single simple condition. This gateway lets you define a complex predicate that can reference multiple process variables and use logical operators (and, or, not) to determine which outgoing path to take, or even how many paths to activate. That’s why it’s the best fit for “uses complex logic.”

In contrast, Exclusive Gateways pick exactly one path based on the first true condition, Inclusive Gateways may take multiple paths but rely on simpler per-path conditions, and Parallel Gateways simply split or join flow without evaluating conditions. Use a Complex Gateway when simple on/off decisions aren’t enough and you need a more intricate rule set to drive the flow.
