• Question 2:

  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. 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
  B. 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.
  C. 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.
  D. in each view object, simply type the predicate into the WHERE clause of the View Object Editor query page.
  C. 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.

• Question 3:

  Consider a case where an application does not respond as predicted when a user submits data. Where would you set a breakpoint to debug the issue? (Choose the best answer)

  A. the value binding for the iterator on the pagedef for the view
  B. a view activity that is used to determine where to send the user
  C. the partialTriggers property of the data bound component in the view
  D. the Apply Request Values phase of the life cycle
  A. the value binding for the iterator on the pagedef for the view

• Question 4:

  View the Exhibit

  

  You have defined a compare validation rule on the CommissionPct attnbute of the Employees entity object such that Commission must be greater than zero. How would you define that the validation rule applies only to those with the Jobld "SA_MAN" using the declarative features of ADF Business Components? (Choose the best answer.)

  A. Remove the current validator and, instead, write a method validator in Java and use an if statement to check the value of JoblD.
  B. Remove the current validator and, instead, write a script validator using Groovy and use an if statement to check the value of JoblD.
  C. Remove the current validator and, instead, write a regular expression validator to check the value of JobID
  D. The entity object has a Validation Execution tab and you use this to set a conditional execution expression Jobld = "SA_MAN".
  E. Change the literal value in the current validation rule to be if Jobld = SA_MAN then return 0.1 else return null.
  B. Remove the current validator and, instead, write a script validator using Groovy and use an if statement to check the value of JoblD.

• Question 5:

  Which statement is true about the difference between an Action binding and a methodAction binding? (Choose the best answer.)

  A. None; they are used interchangeably.
  B. 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
  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. 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
  E. 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
  E. 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

• Question 6:

  Select two true statements about JSF components. (Choose two.)

  A. They can generate only HTML markup.
  B. They can contain other JSF components.
  C. They can be manipulated from a managed bean.
  D. They always translate to a visual component on the user interface.
  B. They can contain other JSF components.
  C. They can be manipulated from a managed bean.

• Question 7:

  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 34321

  Ski hat 100?

  38997 Downhill ski poles 30315

  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.
  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.

• Question 8:

  Which statement describes the Oracle implementation of model-view-controller (MVC)? (Choose the best answer.)

  A. Oracle ADF provides a "pure" implementation of MVC. with the model layer handling page navigation and encapsulating business logic.
  B. ADF Controller provides support for application tasks such as validation, state management, security, and business-process orchestration.
  C. ADF bindings provide a layer of abstraction on top of the business services to enable the view and controller layers to work with different implementation
  D. JSF Controller is the best choice for ADF Faces-based web applications because it enables you to break up an application's page flow into re-usable fli

• Question 9:

  Consider the JSF managed bean code to execute a function in ADF Business Components via an af:button actionListener on a page:
