Subflows are described by which statement?

• A. they can be used to reuse logic within the same application without external calls
• B. they are deprecated
• C. they run asynchronously by default
• D. always run synchronously and inherit processing and exception strategies of the calling flow

Answer: (D)

Sub-flows are a way to encapsulate reusable processing that is invoked from a parent flow via a flow reference; they don’t have their own inbound message source. They execute as part of the caller’s processing. Because they’re part of the same flow chain, they run synchronously by default and use the same processing steps and exception handling configuration as the flow that called them. This means any error handling or retries defined at the caller level applies to the sub-flow as well, keeping behavior predictable and aligned with the parent flow. Sub-flows can include components that call external systems, but that’s not what defines them; their defining trait is the synchronous execution and inherited exception/processing behavior.
