Question 75
Correct Answer: A
The flow provided starts with an HTTP POST request to the listener with the payload 'Hello-'. The flow then publishes this message to JMS with the destination 'one'. In the 'oneJmsQueueListener' flow, 'JMS1-' is appended to the payload, but since publishing is asynchronous, this change is not reflected in the main flow at this moment. Next, the main flow sends an HTTP POST request to '/data', appending 'HTTP-' to the payload, making it 'Hello-HTTP-'. The 'twoJmsQueueListener' flow is triggered by the publish-consume processor, appending 'JMS2-' to the payload. Since publish-consume is synchronous, this change impacts the payload in the main flow, making it 'Hello-HTTP-JMS2-'. Finally, 'Three' is appended to the payload, resulting in 'Hello-HTTP-JMS2-Three'.

The flow starts with the payload "Hello-" from the POST request. Since the VM-Publish processor is asynchronous, the Set Payload in the flow oneJmsQueueListener does not change the payload at this moment. Continuing to the Request processor, a "HTTP-" is being appended to the payload. Next is the VM-Publish consume processor which is synchronous and "JMS2-" is being appended to the payload. At the end of the flow, the Set Payload processor appends "Three" to the payload.

Yes exactly. Publish = Asynchronous, because message is sent and does not wait for response. Publish consume = Synchronous, because flow is waiting for response, hence changing the payload (in this specific case).
