What message exchange pattern will require you to explicitly correlate the request and the
response in an EBF?
A.
Fire-and-forget pattern
B.
Subscribe pattern
C.
Synchronous request-response
D.
Asynchronous request-delayed response pattern
Explanation:
A) If the control is to be blocked until a response is returned to the point of
invocation, choose EBF Request-Reply pattern. This would be a synchronous call.B)If after the EBF is invoked the triggering point does not wait for the response and continues on,
this invocation of the EBF would be an asynchronous call.
Check whether the processing of the EBF results in a response.
Is there a need to correlate the request and the response?
If the answer is yes, this is a case of delayed response. Use the EBF request-delayed response
pattern. If the answer is no, then choose the EBF fire-and-forget pattern.
C) Any EBF operation invoked because of a subscription to a publish event should use the EBS
subscribe pattern.
