[All Salesforce MuleSoft Developer II Questions]

Two APIs are deployed to a two-node on-prem cluster. Due to a requirements change, the two APIs must communicate to exchange data asynchronously.

AIf the two APIs use the same domain, the VM Connector can be leveraged

BThe VM Connector is used to inter-application communication, so it is not possible to use the VM Connector

CInstead of using the VM Connector use <flow-ref>directly

DIt is not possible to use the VM Connector since the APIs are running in a cluster mode and each mode has it own set of VM Queues

Show Suggested Answer

Suggested Answer: A

To communicate asynchronously between two APIs deployed to a two-node on-prem cluster, the developer can use the VM Connector if the two APIs use the same domain. The VM Connector allows passing messages between different Mule applications within a single Mule runtime instance or across different instances using shared memory or persistent storage. If two APIs are deployed under the same domain, they can share resources such as VM queues and communicate asynchronously using VM Connector operations.

I'm pretty sure the correct answer is option A. The VM Connector is designed for exactly this kind of inter-application communication scenario.

Haha, this question is a real head-scratcher! I'm going to go with option B just to mess with the graders.

Option C is the way to go. Instead of using the VM Connector, we should use a direct flow-ref to enable the communication between the APIs.

Option D seems more plausible to me. The APIs are running in a cluster mode, and each node has its own set of VM Queues, so the VM Connector can't be used.

Yes, you're right. Using the VM Connector in this scenario would not work due to the separate VM Queues for each node in the cluster.

I'm not sure, but option D makes sense since each mode has its own set of VM Queues.

I think option A is the best choice because the APIs are in the same domain.
