What happens when a Message exception occurs in a Mule flow?

• A. Normal flow execution stops; the message is passed to the FIRST processor in the exception strategy
• B. The flow retries automatically
• C. The message is dropped and processing continues
• D. The exception is logged and ignored

Answer: (A)

When a Message exception occurs, the normal flow stops and control moves into the flow’s error handling. Mule activates the exception strategy for that flow and begins processing with the first processor defined in that strategy. This is the entry point for handling the error, where you can log, transform, route, or propagate the error as needed. Automatic retries aren’t guaranteed just by the exception occurring unless you explicitly configure a retry within the exception strategy, and the message isn’t simply dropped or ignored—the flow either handles the error via the strategy or propagates it if unhandled.
