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

1. Anna has been testing a model and is concerned about the time certain actions seem to be taking. Her development environment is a high-end system, and other portlets she has developed have not exhibited the kind of response time lag that she and her testers perceive. She suspects one of the data services builders is experiencing network latency, but is unsure where the real problem lies. What actions can she take to help isolate the performance issue?

A) Dedicate a larger Java HEAP_SIZE to the main method associated with the model that is suspect.
B) Consult the performance log, which is created by default with each model run.
C) System tracing is enabled by default. Anna can check SystemTrace.log for model action times.
D) Enable system tracing in the run configuration tab to log the execution time for each action (page or method).

2. Phil needs to use a set of resource bundles to localize the portlets that he is building. What steps can he use to accomplish this task?

A) Phil can use the Imported Resource builder and the Simple Locale Profile Selection Handler to select and import the correct bundle. Then use Data Page, View and Form, and the other UI builders to construct the localized UI with strings from the imported bundle.
B) Place the bundles into the project and use the Imported Page builder and it's localization inputs to automatically apply the correct resource bundle to the page imported into the portlet.
C) Place the bundles into the project ensuring that the bundles include the appropriate language and country codes. Then use a Localized Resource builder to import the proper bundle according to the locale determined for the user of the portlet.
D) Use the Data Services builder to generate a service that selects the appropriate bundle based upon the locale of the request and returns it as an XML structure that can be fed directly into the Data Page or View and Form builders.

3. Yolanda needs to add an element to an XML structure that is interacting with an object in IBM Web Experience Factory. Assuming the XML structure exists, what would be the method that she should call to add a new child element?

A) addChildElement("ElementName")
B) setNameWithText("ElementName")
C) addChildWithText("ElementName")
D) setName("ElementName")

4. Jeremy is about to implement the configuration for his portlet, allowing the IBM WebSphere Portal administrator to set parameters for the portlet. In which builder call should he set the behavior for the profile set that contains the profile fields for this purpose?

A) Portal Configuration
B) Profile Adapter
C) Portlet Adapter
D) Profiled Service Call

5. Jim has a model with multiple profile sets. He wants to test different combinations of the profiles. Where should he go to accomplish this task?

A) A newly created Profile Execution builder call
B) The Applied Profiles view, represented as a tab
C) The Navigator, where it can be dragged and dropped to the new model
D) The Profile itself, from the original input (it can be copied form here)
