Hi all,

I am looking for the answer of the following question. Please help.

What is the effect of using XML in an SOA?

A. The enterprise service bus (ESB) mediates during service invocation.
B. Web services are invoked.
C. Business processes are modeled.
D. The service repository provides persistence.

In the context of a business process in SOA, which statement most accurately describes what a transaction is?

A. Transactions are reliable updates via queued writes from the service requestor using message-oriented middleware.
B. The relevant standards as related to SOA and transactions are WS-Coordination, WS-AtomicTransaction and WS-BusinessActivity.
C. During the execution of service invocations, transactions represent the activity in your service workflow.
D. The WS-Coordination framework enables existing transaction processing, workflow, and other systems for coordination to hide their
proprietary protocols and to operate in a heterogeneous environment


Thanks
Benson
