Question 1

Which two statements are true about attribute value bindings? (Choose two.)

A. An ADF Faces inputText and an outputText component displaying the same attribute value would typically use separate bindings.

B. Multiple Ul components can reference the same attribute value binding.

C. An attribute value binding can be created only by dragging and dropping a data control attribute onto a page.

D. Creating an attnbute value binding by dragging and dropping from the Data Controls window references, by default, an attribute value in the current row in the collection.

E. Each data control attnbute can have only one attnbute value binding.

Correct Answer: A,E

Question 2

Your page contains the following code that is invoked on an action by the current user;
<af:setPropertyListener from-"#{applicant:surname}" to-'#(...)" type-'action'7>
To receive the value from the to property of the afsetPropertyListener, you create a
managed bean as follows
package view;
public class Employee { String lastName;

</managed-bean>
What EL expression would you write in the af setPropertyListener "to" property to write the value to the lastName string of the Employee class? (Choose the best answer.)

A. to^frfpageFlowScopeEmplastName}"

B. to="#{pageFlowScope emp LastName}"

C. to="#{lastName}"

D. to="#{LastNamer

E. to="#{emp.lastName}e

F. to="#{pageFlowScope.emp.lastName):

Correct Answer: F

Question 3

Which statement is true about creating a method at the application module level? (Choose the best answer.)

A. You cannot create methods at the application module level.

B. Application module methods are best suited to writing validation logic for entity objects.

C. Because ADF provides no way at run time to automatically create or delete view object records, you must create application module methods to do this.

D. Application module methods provide an interface for the view layer to call custom business logic that may work across multiple data views.

E. Methods in an application module allow you to manipulate Ul components in the ViewController project

Correct Answer: D

Question 4

You are prototyping an ADF application that uses ADF Business Components. However, the database schema that you can connect to does not contain any tabl Which two declarative options are available to you to provide hard-coded data for the purposes of your prototype? (Choose two.)

A. entity objects with default values

B. placeholder data control

C. declarative managed beans

D. stati c li st vi ew objects

Correct Answer: B,D

Question 5

View the Exhibit

Which three options are true about the scenario in the Exhibit? (Choose three)

A. ADF Faces restricts developers from using the same view object instance across pages, so developers at design time must create multiple separate view object instances.

B. Under the relating AppModuleDataControl in the JDeveloper Data Controls window, each view object instance appears as a separate selectable data collection

C. Two separate view object instances exposed through the application module allow you to apply separate view criteria and bind variable values to show separate result sets.

D. Two separate view object instances allow you, at run time, to maintain two separate current row indicators on each instance respectively, to display separate records at the same time.

E. Two separate view object instances defined through the same application module create separate entity object caches, allowing users to modify records in their own independent transactions.

Correct Answer: B,C,D

Question 6

What should be in a managed bean, rather than a backing bean? (Choose the best answer.)

A. code that manipulates the color of a text field on a JSF page

B. data that is used on another page in the task flow

C. code that opens a pop-up in the page

D. data that is used to decide if a field is shown as mandatory or not

Correct Answer: B

Question 7

View the Exhibit

Which option represents the steps to add a relationship between OrdVO and ItemVO and create a master-detail hierarchy for the same in the data model? (Choose the best answer.)

A. Select View Link from the Components window and draw a line on the diagram from ItemVO to OrdVO. Use the Application Module Editor to define the data model for the hierarchy.

B. Create a view link with ItemVO as the source and OrdVO as the destination and define the linked attributes. Use the Application Module Editor to nest the OrdVO instance beneath the ItemVO instance.

C. Create a view link with OrdVO as the source and ItemVO as the destination and define the linked attributes Use the Application Module Editor to define the data model for the hierarchy.

D. Select Association from the Components window and draw a line on the diagram from OrdEO to ItemEO diagram and select Generate View Link

Correct Answer: C

Question 8

You have two entities, ItemEO and ProductEO. ItemEO contains the Orderld, ttemld, Productld, Price, and Quantity attributes. ProductEO contains the Id, ProductName, and ListPrice attributes You need to return rows as shown in the table
Orderld Itemld Productld ProductName 101 1001 34321 Ski hat 101 100? 38997 Downhill ski poles 102 1003 30315
Swim goggles
103
1004
31876
Baseball mitt
How would you create a view object to encapsulate these rows? (Choose the best answer)

A. Create a view object based on the ItemEO entity and create a view criteria to add ttemEO PRODUCTJD - :productld. Define productld as a bind variable to be passed in by the Ul

B. Create a view object based on the ItemEO entity and add ProductEO as a reference entity.

C. Create a view object based on the ItemEO entity and modify the WHERE clause to include ItemEO PRODUCTJD = ProductEO ID

D. Create a view object based on the ItemEO entity and change the query mode to Expert Define the query as SELECT Item ORDJD, Item ITEMJD, Item.PRODUCTJD, Product.NAME, FROM SJTEM Item JOIN S_PRODUCT Product ON ltem.PRODUCT_ID=Productld.

E. Create a view object based on the ItemEO entity and modify the generated query to include SELECT ProductEO NAME. ProductEOJD, FROM S_PRODUCT ProductEO.

Correct Answer: D

Question 9

Which option represents the source file(s) that are typically created for you? (Choose the
best answer.)

A. EmployeesView.sql

B. EmployeesView.xml and EmployeesViewlmpljava

C. EmployeesViewlmpljava

D. EmployeesView.xml

E. EmployeesViewRowlmpI java
