IBM C9520-927 Exam Syllabus Topics:

IBM Developing Portlets and Web Applications with IBM Web Experience Factory 8.0 Sample Questions:

1. Sean wants to trace the value of a variable as a model he is running to help track down a problem somewhere in a computation later in the model. How can he trace the value of the variable?

A) Inspect the logging.properties file for variable values because all changes are reflected in this file at run time.
B) Add an entry to the log4j.properties file indicating the model and action to trace.
C) Use the enable Debug Tracing field on the Variable builder.
D) Add a Debug Tracing builder to the model specifying whether to trace all actions or naming a specific action to trace.

2. For faster iterative development and testing, Johan would like to test his models without continually logging in and logging out of the IBM WebSphere Portal server and loading the correct page. Which of the following steps should he take to accomplish this task?

A) Open the model files in a browser after associating the extension .model with the browser.
B) No actions are necessary as models run embedded in the Eclipse or IBM Rational Application Developer IDE by default.
C) Create a run configuration to run the models on an embedded test server.
D) Create a configuration to run the model stand-alone.

3. Christine wishes to leverage the REST Service Call builder's ability to restructure the generated result schema and result structure. How should she do this?

A) She should directly modify the the result schema in the REST Service Call builder's "Result Schema" input and the REST Service Call builder will reshape the data to this structure at runtime.
B) She should choose to follow the steps in either answer B or answer C.
C) She should add a REST Service Call Restructure builder and register it with the REST Service Call builder.
D) She should implement the RestructureFeedData interface, register it, and select it in the REST Service Call builder's "Restructure Type" input.

4. Robin has network access to her IBM WebSphere Portal server, and has deployed a project to it. How does she update the project on the WebSphere Portal server?

A) Regenerate the WAR file and re-save the configuration of the portlet on the server
B) Regenerate the WAR file, its changes will automatically deploy
C) Save and run any model in the project, this will automatically re-deploy
D) Regenerate the WAR file and invoke the proper xmlaccess script

5. Jose is designing web services that will return very large record sets (in the 1000's). He is also designing an IBM Web Experience Factory application to consume them and plans to use Web Experience Factory's Paging features to paginate over the large record sets. How should paging be configured for the web services?

A) He should simply enable paging in the Data Column Modifier builder. Web Experience Factory automatically chunks the data from the backend web service into the app server memory.
B) Jose should consider implementing a start index and fetch size parameter in his underlying web services that return large record sets. Then in Web Experience Factory he can implement the DataRetriever interface which enables the Paging Assistant builder to return "chunks" from the underlying service rather that marshalling the entire record set into the application server's memory.
C) He should use enable the Web Service Call to return a DataRetriever and then add a Paging Assistant builder and point to the variable created by the results of the web service call.
D) He should consider using The Chunked Data Retriever builder, which allows you to specify a start index and fetch size before invoking a web service.
