IBM C9520-927 Exam Syllabus Topics:

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

1. 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 consider using The Chunked Data Retriever builder, which allows you to specify a start index and fetch size before invoking a web service.
B) 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.
C) 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.
D) 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.

2. Heather is preparing to move an application into production and has discovered that there is an option to create a portlet WAR file or an application WAR file. What is the conceptual difference between the two?

A) An application WAR file can include profiling for personalization and configuration, while a portlet WAR file is static and cannot be configured for profiling.
B) An application WAR file can deploy multiple portlets at the same time in an application, while a portlet WAR file represents a single instance of a portlet.
C) An application WAR file is a prerequisite for deploying a portlet WAR file. It represents the container hierarchy for portlets.
D) A portlet WAR file contains portlets designed to run on an IBM WebSphere Portal server or portlet container, while an application WAR file is a stand-alone web application that has no dependencies on WebSphere Portal containers, so it can be deployed to an application server.

4. Which of the following best describes the Discardable Variable builder?

A) This builder stores all variable data in browser cookies, with a specified expiration time after
which the browser discards the values.
B) This builder removes all unused variables from the web application to minimize the size of the
application. The variables no longer show up in the Web Application Design view in IBM Web Experience Factory Designer after applying this builder.
C) This builder can be used to mark a variable created by other builders as discardable so that its
value is not stored past the end of the request,
unless developers specify that it should be cached and for how long to cache it.
D) The Discardable Variable builder has been deprecated and should no longer be used.
