Anintegration developer has been asked to review an implementation of the JavaComponentImpl class. The class implements the AnInterface interface, as shown in the exhibits.


Which concern should the integration developer state in the review?

• A. A line should be inserted between lines 24 and 25 of JavaComponentImpl.java containing: storedA.unset("field1");
• B. Static references to a business object can result in concurrent access of it.
• C. Java components that operate on business objects must implement Java interfaces.
• D. Line 25 of JavaComponentImpl.java should be: storedA.createDataObject("field1", "http://AModule", input1);

An integration developer has been asked to describe how to build an API event handler. Which statement should the integration developer include in the description?

• A. An API Event Handler cannot be packaged together with an Notification Event Handler in the same Java archive (JAR) file.
• B. If the event handler implements the APIEventHandlerPlugin5 interface, then the service provider configuration file must be named com.ibm.task.spi.plugin_nameAPIEventHandlerPlugin5.
• C. If the eventhandler class is an implementation of the APIEventHandlerPlugin interface, then it is not necessary to implement all methods.
• D. The event handler can be deployed as a shared library in WebSphere Application Server, so it can be reused by other enterprisearchive (EAR) files.

Which statement correctly describes SCA?

• A. SCA references that are only available to the service component in which the references are included as stand-alone references.
• B. With SCA, service contracts and implementation details are visible to the client.
• C. An SCA service component definition is included in a file called <SERVICE_NAME>.bpel
• D. SCA provides a common invocation model with well-defined interfaces and encapsulation into modules.

An integration developer needs to implement a solution for a company, which has three different services based onthe JMS protocol. The requirement is to have a single entry point exposed as a JMS binding for all the services. Common processing will be performed on all requests entering this single entry point. Then, the request will be routed to the appropriate service endpoint. The endpoint determination should be done at runtime using external registry lookup so that in the future, the company can associate new services without redeploying the solution. Which implementation pattern should the integration developer choose to meet the requirement?

• A. A mediation flow with an interface that has an operation for each service.
• B. A mediation flow created from a Dynamic Service Gateway.
• C. A business state machine using different operations, such as different events.
• D. A BPEL process with several Receive activities.

An integration developer is testing a long-running process applicationfor a customer. When the business process receives a request, it invokes several other SCA services. During integration testing, the developer finds that an unexpected failure has occurred. Which troubleshooting method gives the integration developer a detailed hierarchal view of the invocation record, including input and output data?

• A. Change the log detail level to the SCA.* option in the running server.
• B. Enable cross-component trace (XCT)with the Data Snapshot option.
• C. Load all the other integrated SCA services in the business process to the same workspace.
• D. Put breakpoints at various places in the business process.
