A. The SOA Service should implement an asynchronous "get account" method because that matches the legacy system access provided.

B. The SOA Service should implement a synchronous "get account" method because that Is what the service consumers have requested. A new synchronous Interface to the legacy system should be created.

C. The SOA Service should implement two synchronous methods. The first method is a "send account request" and the second method is a "get account response." This meets the synchronous interface request of the service consumers while matching the existing interface to the legacy system.

D. The SOA Service should implement a synchronous "get account" method because that is what the service consumers have requested. The SOA Service should use the synchronous-to-asynchronous bridging pattern and use the existing interface to the legacy system.

E. The SOA Service should implement a synchronous "get account" method because that is what the service consumers have requested. The SOA Service should use the store-and-forward pattern and use the existing interface to the legacy system.
