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

1. Sam has an older model that uses the View and Form builder. He created this model before the IBM Web Experience Factory theme support existed and would now like the View and Form builder to use the default theme. What is the best way for Sam to accomplish this task?

A) Add a new View and Form builder to his model and remove the old one.
B) Open the View and Form builder call in his model and select the Use Theme field.
C) Add a Theme builder to his model and select the Use Theme field.
D) Set the default bowstreet.themeFile property to true, so that all builders are forced to use the default theme.

2. What should Linus do to declare a model as a portlet?

A) Generate a model with a specific file path to its resources.
B) Modify the portlet.xml file with a text editor to include file paths.
C) Add a Portlet Adapter builder call to a model.
D) Generate a portlet WAR file, which automatically deploys all models as portlets.

3. 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) 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.
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.

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) The Discardable Variable builder has been deprecated and should no longer be used.
D) 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.

5. Sam is using the CMIS Document Access builder to allow his model to make service calls to FileNet. His FileNet administrator has told him that he can use the basic HTTP Access Scheme, and has provided him a user name and password. How would he set this up?

A) Select Basic Authentication for the Runtime Authentication input and specify username and password in /WEB-INF/config/cmis_config/designer/defaultCredentials.properties.
B) Select Basic Authentication for the Runtime Authentication input and enter username in Runtime User name and password in Runtime password.
C) Create a java class that implements com.bowstreet.builders.webapp.cmis.CmisHttpConnection with class name BasicHttpConnection.
D) Select Basic Authentication for the Runtime Authentication input and enter username and password as the JVM properties CMISUserName and CMISPassword in IBM WebSphere Application Server administration.
