質問 2：

A. by selecting the Shared Library check box when adding libraries and JARs to a project
B. by using a source control system to share components
C. by creating an ADF Library of components and deploying it to a shared location

質問 3：
The current page includes the following entries in its page definition file:
<bmdings>
<attnbuteValuesfterBinding="EmployeesView1 Iterator" id="Email">
<AttrNames>
<ltemValue="Email"/>
</AttrNames>
</attnbuteValues>
</bindings>
Programmatically, in a managed bean, you need to read the current EmployeesView's
email into a string. You write the following code to do this:
DCBindingContainer be = (DCBindingContamer)BindingContext.getCurrent
().getCurrentBindingsEntry();
XXXXXX emailBinding = <XXXXXX)bc.findCtrlBinding("Emair);
String emailValue = emailBinding.getAttribute().get$tring();
What single class must you substitute for XXXXXX in the two locations in the code?
(Choose the best answer.)
A. DCValueBinding E BCValueBinding
B. JUCtrlValueBmding
C. JUCtrlActionBinding
D. CtrlBindmgContext
正解：B

質問 4：
Which two statements are true about an af:panelStretchl_ayout component? (Choose two.)
A. You can specify the vertical size for the top facet in pixels.
B. Components placed in the center facet stretch to fill the horizontal space regardless of their containing layout container.
C. a component placed in the center facet dynamically spaces out vertically to fill out the page height.
D. Facets without content in them do not show up at run time.
E. if the top facet has more content then fits vertically, it automatically adds a vertical scroll bar.
F. You cannot include another panelStretchLayout component in the bottom facet.
正解：C,E

質問 5：
Your database has a strict security requirement that whenever users select from any table in the database schema, they must append the select statement with an additional where predicate that returns only records WHERE owner = :pUserName. This restricts users to seeing only records that they own.
When you design and develop the ADF Business Components in your ADF application, there will be more than 100 view objects that select against this database. You want to build a solution that not only ensures all your developers, when writing view objects, meet the database's strict security requirement, but takes the least amount of development effort for your entire team and is easy to maintain in the long term.
Identify the correct solution. (Choose the best answer.)
A. Create a complete set of custom ADF Business Component framework classes for your business components and then override your custom ViewObjectlmpI class to programmatically modify each view object's where clause at run time to append the predicate.
B. Define a view criteria on each view object at design time to apply the predicate to the corresponding view object, ensuring the view criteria is defined against the view object instance in the Application Module Editor
C. Override each view object's ViewObjectlmpI class methods to programmatically modify each view object's where clause at run time to add the predicate to the select clause regardless of the query executed.
D. in each view object, simply type the predicate into the WHERE clause of the View Object Editor query page.
正解：A

質問 6：
Consider the following code:
<af:inputTexl valueChangeListener="#{myBean.handleChange}r .../>
<af:commandButton actionListener= n#{myBean.doAction}" action="#
{myBean qetDestmation}" .../>
At run time, a user modifies the value in the af:inputText control, then presses afcommandButton
Assuming no errors are raised, which option represents the managed bean code invoked in the correct order1? (Choose the best answer.)
A. myBean handleChange, myBean doAction, myBean.qetDestination
B. myBean.doAction, myBean.handleChange
C. myBean.handleChange, myBean.doAction
D. myBean.doAction, myBean handleChange, myBean.getDestination
正解：C

質問 7：
Which statement is true about the difference between an Action binding and a methodAction binding? (Choose the best answer.)
A. Action bindings are used to bind to built-in operations such as Create, Delete and Next, whereas a methodAction binding is used to bind to custom methoc
B. None; they are used interchangeably.
C. Both are bindings to methods defined in a business service, but an Action binding is used to bind to a Ul component whereas a methodAction binding is 01
D. An Action binding is a binding to a method defined in the business service exposed through a data control, whereas a methodAction binding is used to bin
E. Both are bindings to methods defined in a business service, but a methodAction binding is used to bind to a Ul control whereas an Action binding is only a
正解：A

質問 8：

A. displays a pop-up that allows the user to enter a value for the current row
B. calls a method
C. calls the updateCustomer page
D. determines whether the user is navigated to the updateCustomer or callEmployeeTF activity
正解：C

質問 9：
You create a new ADF Faces page called emp.jspx and bind some data controls to that page. You notice a file called empPageDef.xml. What is this file for? (Choose best Answer)
A. it is a template file into which you can write any managed bean code.
B. it is the file that contains the definition of the bindings to your data-bound components.
C. it js the page template definition file that represents the chosen quick start layout.
D. it defines the binding context for all pages in your application.
E. it is the page definition that contains the XML representation of the page layout and the components on that page.
正解：B
