質問 2：
A partner needs to access services that are defined in one of your Service Composite Architecture (SCA) applications via a web service interface. Which approach (and accompanying reasoning) describes a loosely coupled and robust solution?
A. Use Oracle Service Bus to provide an Interface layer over your SCA application. This enables you to hide the locations of your SCA application, perform load-balancing across those endpoints, and provide the ability to define service level agreements to help ensure that you are meeting your contractual obligations to the partner.
B. Allow the partner simply to connect directly to the SCA application. This provides the best performance and helps keep the partner happy.
C. Use Oracle Service Bus to provide an interface layer over your SCA application. This enables you to "skin" your SCA application with a web service interface and still provide a robust experience to the partner.
D. Use the Mediator component to provide a web service interface to your SCA application. This arrives you the flexibility of using the industry standard XSLT technology to perform translation and transformations.
