Which statement best describes internal versus external messaging destinations in Mule?

Explanation:
In Mule, the distinction comes from where the endpoint lives and how it’s accessed. VM endpoints are in-memory and operate inside the Mule runtime, used for fast internal communication between flows in the same Mule instance. They aren’t exposed to external clients. External destinations rely on a JMS broker, which lets external applications connect to producers or subscribers. JMS topics are a broker-based, external-access pattern (publish/subscribe), which is why stating that JMS topics can be used externally captures the intended behavior. So the best description is that VM queues are internal only, while JMS topics can be used externally.
