S90.08 Advanced SOA Design & Architecture Questions and Answers

The Legacy Wrapper pattern should not be applied in conjunction with the Process Centralization pattern because legacy systems do not possess enough autonomy to be effectively composed.

The Messaging Metadata pattern can be applied to supplement messages with metadata that can be used for tracking purposes when also applying the Reliable Messaging pattern.

The Protocol Bridging pattern is often used with the Legacy Wrapper pattern as a means of performing data model transformation between service inventory-wide data models created through the application of the Schema Centralization pattern and the underlying proprietary legacy format.

All of these statements are true.

You will need to determine who will own and maintain the service agents.

Changes to a single service agent can impact multiple services throughout a service inventory.

Service agents need to be versioned, just like services.

All of the above.

Service agents can check for policy compliance at runtime.

A policy framework that supports both the definition of policies and their consistent runtime enforcement is essential to meeting the goals of the Policy Centralization pattern.

Enterprise service bus products sometimes use proprietary policy formats which can lead to vendor lock-in and incompatibilities with other enterprise service bus products.

All of these statements are true.

Enterprise service bus products commonly provide data model transformation features.

Orchestration products commonly provide data model transformation features.

The Service Broker compound pattern includes the Data Model Transformation pattern.

All of these statements are true.
