  Swim goggles 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 add ProductEO as a reference entity.

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

  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 create a view criteria to add ttemEO PRODUCTJD - :productld. Define productld as a bind variable to be passed in by the Ul

  E. 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.

  Correct Answer: E

• Question 52:

  The current page includes the following entries in its page definition file:

  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 =

  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. CtrlBindmgContext

  B. JUCtrlActionBinding

  C. JUCtrlValueBmding

  D. DCValueBinding

  E. BCValueBinding

  Correct Answer: C

• Question 53:

  The EmployeesVO view object is based on the Employees table and includes a Deptld attribute.

  However, Deptld is not really meaningful to the end user and so, for each employee returned by EmployeesVO. you need to show the correct DepartmentName, which comes from the Departments table and is referenced by the EmployeesVO Deptld attribute.

  How can you achieve this behavior by using the declarative features of ADF Business Components? (Choose the best answer.)

  A. Add a transient attribute to EmployeesVO and set its value to select DepartmentName from Departments where Deptld = EmployeesView.Deptld

  B. Create a database view to join the Departments and Employees tables and base the view object on that view.

  C. Define that EmployeesVO is also based on the Departments entity object. Then select "Add attribute from entity" in the EmployeesVO view object and select DepartmentName from the Departments entity object.

  D. For the EmployeesVO view object, select the query and add WHERE Employees DEPARTMENTJD = Departments.DEPARTMENTJD

  E. Add a transient attribute called DepartmentName in the view object and, in the ViewRowlmpI class, override the getDepartmentName() accessor to: return (String) getAttributelnternal (DEPARTMENTNAME);

  Correct Answer: A

• Question 54:

  When you manually create a binding such as an attribute value binding, what name would you give to the binding? (Choose the best answer.)

  A. a name that reflects the Ul component to which it is bound

  B. the page name suffixed with the Ul component name to which it is bound

  C. the page name suffixed with the data control name

  D. the name of the data control attribute to which the binding refers

  E. an EL (Expression Language) of the form #{bindmgs value}

  Correct Answer: B

• Question 55:

  Consider a development organization divided into two teams, one developing ADF Business Components and related methods, and one developing the view and controller layers. What two steps would the Business Components team perform to deliver the results of their work to the other team'? (Choose two.)

  A. Share the root ApplicationModulelmpI file on the file system or other shared location.

  B. Create an ADF Library JAR file for the model project

  C. Create a path to the ADF Library JAR file in Tools > Manage Libraries

  D. Add the ADF Library JAR to the ViewController project

  E. Share the ADF Library JAR file on the file system or other shared location

  Correct Answer: BD

• Question 56:

  How are ADF components shared among applications? (Choose the best answer.)

  A. by using a source control system to share components

  B. by selecting the Shared Library check box when adding libraries and JARs to a project

  C. by creating shared application modules and ensuring all developers use them

  D. by defining a custom JAR file and sharing it in a source control system

  E. by creating an ADF Library of components and deploying it to a shared location

  Correct Answer: E

• Question 57:

  You have three application modules: A, B, and C. Application modules B and C are nested under the root application module A. Which statement is true when committing the nested application module B? (Choose the best answer.)

  A. No view objects are committed

  B. Only changes to view objects exposed through application module B are committed

  C. On|y changes to view objects exposed through application modules A and B are committed

  D. All changes to all view objects exposed through all application modules A, B, and C are committed.

  Correct Answer: C

• Question 58:

  For what purpose would you use the entity object attribute setting Change lndicator?(Choose the best answer.)

  A. to highlight the attribute in the Ul with a border when the original attribute value has been changed

  B. to fire an entity object custom method as soon as the original attribute value has been changed

  C. to automatically lock the corresponding record in the database

  D. to automatically refresh the attribute value if the underlying data in the database is changed by another user

  E. to define an attribute that the framework uses to check whether the update is about to happen on underlying stale data in the database

  Correct Answer: C

• Question 59:

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

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

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

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

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

  E. 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.

  Correct Answer: CD

• Question 60:

  Select three benefits that ADF Data Controls provide. (Choose three.)

  A. They abstract the Ul developer from the technology used to implement business logic.

  B. They reduce the need to write managed beans.

  C. They automate Ajax updates to the Ul.

  D. They enable drag-and-drop of data objects to Ul component bindings.

  E. They directly connect your Ul to the database tables.
