Question 1:
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
Correct Answer: C

What is the first step you perform to secure an ADF application? (Choose the best answer.)

E. Deploy the application to a Java EE Security-enabled server to test the user roles.
F. Grant roles access rights to pagedefs for views in unbounded task flows.
Correct Answer: ABC
Question 5:
Which three statements are true about declarative features of view objects? (Choose three.)
A. You can use view object bind variables to parameterize a view object where clause with values supplied at run time.
B. By default, a view object instance retrieves all database rows into the view object cache.
C. To implement master-detail behavior between two view object instances, you define an association between those instances.
D. a view accessor defines a validation expression that you apply to a view object attribute.
E. A view object can include attnbutes whose values are based on SQL expressions rather than mapping directly to a database columr
F. A view object definition can include many view criteria but you can choose which view criteria to apply for each view object instance.
Correct Answer: ACE
Question 6:
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 provide an interface for the view layer to call custom business logic that may work across multiple data views.
C. Application module methods are best suited to writing validation logic for entity objects.
D. Methods in an application module allow you to manipulate Ul components in the ViewController project
E. 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.
Correct Answer: B
Question 7:
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
Correct Answer: E
Question 8:
View the Exhibit
Which three options are true about the scenario in the Exhibit? (Choose three)
A. 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.
B. 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.
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. Under the relating AppModuleDataControl in the JDeveloper Data Controls window, each view object instance appears as a separate selectable data collection
E. 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.
Correct Answer: ACD
