Question 5

A financial application uses a `Scatter-Gather` router to send a loan application to three different banks simultaneously. If the second route fails with an error while the first and third routes succeed, what happens to the execution of the flow immediately after the Scatter-Gather scope?

Accepted Answer

The flow throws a `MULE:COMPOSITE_ROUTING` error and enters error handling.

The flow continues with the results from the two successful routes, ignoring the failure.

Answer

The flow stops immediately when the error occurs, cancelling the other routes.

Answer

The flow retries the failed route automatically before proceeding.

Question 6
