Why would you use the Mediator component in a Service Component Architecture (SCA) application Instead of using Oracle Service Bus?

• A.Oracle Service Bus runs out side of a SCA application. Therefore, the Mediator is the only choice for translation and transformation tasks in an SCA application.
• B.The Mediator is much faster than Oracle Service Bus.
• C.The Mediator supports transactions, but Oracle Service Bus does not.
• D.It is always better to use Oracle service Bus Instead of the Mediator.

A customer demands access to your Service Composite Architecture (SCA) application.
However keeping with the customer's company standards, the interface must be EJB 3.0.
Which solution meets the needs of the customer while requiring the least amount of time, effort, and architectural change for you?

• A.Explain to the customer the importance and flexibility of modem web services, and encourage the customer to learn some new skills.
• B.Create a small EJB 3.0 application that interfaces directly with your SCA application. This approach hides the web service interface from your customer while adding the smallest amount of overhead in the process
• C.Use the Mediator component to provide an EJB 3.0 interface in addition to the existing web service interface. This approach adds the least amount of overhead to each call.
• D.Create an EJB 3.0 interface using Oracle Service Bus, which, in turn, invokes the SCA application through its native web service interface. This approach hides the web service Interface from your customer while adding the smallest amount of overhead in the process.

You are creating a web service interface to a legacy system that can handle only five concurrent calls.
What feature of Oracle Service Bus enables you to define this restriction?

• A.Choking
• B.Throttling
• C.Caching
• D.Endpoint management

Over a period of time, you have deployed three versions (1.0, 1.1, and 1.2) of a SOA application X to a three-node SOA cluster. All versions of X subscribes to a business event named createCustomer and instantiate a new BPEL process Y on receiving the event.
At runtime, how many SOA composite instances are generated when createCustomer business event is fired?

• A.1
• B.3
• C.9
• D.0

Which statement is true about how the BPEL Process Manager works?

• A.If the delivery policy for a synchronous BPEL process is set to async.persist, messages to the system are saved in the delivery store before being picked up by the service engine.
• B.If the transaction property for a synchronous BPEL process is set to requiresNew transaction, a new transaction is created for the execution and the existing transaction (if there is one) is suspended.
• C.If the delivery policy for a synchronous BPEL process is set to sync, the instance-initiating message is not temporarily saved in the delivery layer.
• D.If the transaction property for an asynchronous BPEL process is set to required, the BPEL process joins a caller's transaction (if there is no one) or creates a new transaction (if there is no transaction)
