質問 1：
Samantha inherits a portlet from a coworker that should be using partial page refresh within tab panes. The entire portlet (but not the portal page) seems to be refreshed on each action within the portal page. Which of the following causes could trigger such behavior?
A. The portal page on which the portlet is placed was set to server-side aggregation and should be switched to client-side aggregation.
B. IBM Web Experience Factory Smart Refresh has been disabled using a Theme builder.
C. The portlet needs to have a Global AJAX Enablement builder added to enable the correct behavior.
D. The outer page that contains the tabs has a <form> tag wrapping the tab panes, so the forms within the tab panes are stripped out by Web Experience Factory to avoid invalid HTML and thus the outer page's form is submitted and the outer page refreshed, for each action.
正解：D

質問 2：
Lydia needs to create a set of CRUD services for a database table. The columns that must be retrieved from the database are a subset of those defined for the table. What is the most efficient way for Lydia to create these services?

B. Create a SQL Call builder for each CRUD operation and use a SQL Statement override to explicitly choose those columns needed for the SELECT operation.
C. Use the SQL Data Services builder to generate all of the CRUD operations and explicitly specify the set of columns used for the List and Retrieve operations.
D. Use the SQL View and Form builder to define the CRUD services and automatically generate the CRUD user interface.

質問 5：
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 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.
C. 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.
D. The Discardable Variable builder has been deprecated and should no longer be used.
正解：B

質問 6：
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?
