To share data between Mule applications using a VM connector, what is required?

• A. Put the Mule applications in the same default Mule domain
• B. Run on the same machine
• C. Use the same data store
• D. Put the Mule applications in the same non-default Mule domain

Answer: (D)

VM transport shares data through in-memory destinations inside a Mule domain. The domain defines an isolated runtime space that all apps in that domain can access, so the VM queues and endpoints are visible only to apps within the same domain. Therefore, to share data between Mule applications using VM, the apps must belong to the same domain. The option specifies using a non-default domain, which is the typical setup when you want a clearly defined, shared domain for related apps. Put simply, if the apps aren’t in the same domain, they won’t see the same VM destinations, so data sharing won’t work. Other choices don’t fit because VM sharing isn’t about being on the same machine or using a particular data store; it’s about being in the same domain.
