You work as a Microsoft BizTalk Server 2006 administrator at Domain.com. You received instruction to deploy a business rules policy.

You received reports from your business users stating that a new version of a business rules policy needs to be deployed. You must ensure that the previous version of the policy is inaccessible. However you discover that you are unable to find the appropriate policy version in the dropdown list when you launch the Business Rules Engine Deployment Wizard and select Deploy.

What is the most likely cause of this?

A.
The new policy version has not yet been published.

B.
The existing policy version has not been undeployed.

C.
Your Business Rules Engine Deployment Wizard points at the wrong Rule Store.

D.
There are no orchestrations with a Call Rules shape that use the new policy version.

Explanation:
Only published policy versions appear in the dropdown list of the Business Rules Engine Deployment Wizard, hence your inability to find the appropriate policy version in the dropdown list.

Incorrect Answers:
B: Undeploying a previous version for an updated version to be available for deployment is unnecessary. Even though it is mentioned that the previous version should be undeployed, it is not a requirement to enable the deployment of the new version.
C: You could be pointing the wizard to the wrong Rule Store. In most cases, only a single Rule Store is used so it would have been apparent with the first rules deployment if there were a problem of this type. So even if this is the problem, it is not the most likely problem.
D: The consumer (or lack thereof) of a rule policy has no impact on the deployment of the policy version. Thus this option is superfluous.
