which messages aresent out. When the messages are answers and come back in the messages need to be associated with specific orchestration instances.What should you do?

You work as a Microsoft BizTalk Server 2006 architect at Domain.com. You have received instruction from the Domain.com CIO to establish a business transaction.

The design you are in the process of creating should call for an asynchronous operation in which messages are
sent out. When the messages are answers and come back in the messages need to be associated with specific orchestration instances.

What should you do?

A.
A Correlation must be set up on one or more message properties.

B.
A Long-Running transaction should be created to contain the critical elements.

C.
You should take no action as the messages will collate according to the filters applied to establish the subscription in the first place.

D.
An Atomic transaction should be crated to contain the critical elements.

Explanation:
You should remember in the scenario that Correlation is the mechanism whereby messages are routed to specific orchestration instances. This is considered to be mandatory when your messages are not correlated correctly.

Incorrect Answers:
B: This option should not be used in the scenario as it will not guarantee the messages will be associated with specific instances.
C: This option should not be considered in the scenario because this alone is insufficient to guarantee successful routing of messages.
D: This option should not be used because by itself an Atomic transaction scope does not guarantee that messages will be associated with a specific instance.
