You work as a Microsoft BizTalk Server 2006 Developer for Domain.com. The development of Integration application is your responsibility at Domain.com. You received instruction to create an orchestration that subscribes to incoming messages.

The design you have been given specifies that your orchestration should employ a publish-subscribe pattern, as opposed to being explicitly bound to any physical ports. To this end you need to make sure that your orchestration’s logical receive port employs the appropriate type of binding.

What should you do?

A.
Ensure that the logical receive port uses Direct binding.

B.
Ensure that the logical receive port uses Dynamic binding.

C.
Ensure that the logical receive port uses Specify Now binding.

D.
Ensure that the logical receive port uses Specify Later binding.

Explanation:
The Publish-Subscribe patterns can be achieved through the use of MessageBox Direct Bound Ports. For activating logical Receive Ports, the subscription is the MessageType and the Filter expression(s).
Thus you need to ensure that the logical receive port uses Direct binding on the orchestration.

Incorrect Answers:
B: The Dynamic binding is used for send ports that need runtime specification of destination and other parameters, it is not a receive port binding type.
C: The Specify Now binding is used to bind physical ports for design-time binding. This is not what is required.
D: The Specify Later binding is used to bind physical ports for deployment-time binding. This will not allow you to employ a Publish-subscribe pattern.
