you nave wnnen a uroovy vanaaiion expression ror me tmpioyees enuiy ODjea. now wouia you customize ine error message to snow rne vaiue 01 rne LastName attribute as all uppercase? (Choose the best answer.)

• A. Add a token to the validation error message and define the token value as adf.object.hints value toUpperCase
• B. Add a token to the validation error message and define the token value as LastName toUpperCase().
• C. insert adf error raise ("< your error message>" + LastName tollpperCaseO) into the validation code as part of the failure processing.
• D. Manually change the error string in the ModelBundle.properties file to be uppercase.
• E. Add a token to the validation error message and define the token value as adf.object.hints toUpperCase.

Which three statements are true about declarative features of view objects? (Choose three.)

• A. a view accessor defines a validation expression that you apply to a view object attribute.
• B. You can use view object bind variables to parameterize a view object where clause with values supplied at run time.
• C. A view object definition can include many view criteria but you can choose which view criteria to apply for each view object instance.
• D. To implement master-detail behavior between two view object instances, you define an association between those instances.
• E. A view object can include attnbutes whose values are based on SQL expressions rather than mapping directly to a database columr
• F. By default, a view object instance retrieves all database rows into the view object cache.

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. JUCtrlValueBmding
• B. DCValueBinding E BCValueBinding
• C. CtrlBindmgContext
• D. JUCtrlActionBinding

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

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

• A. to automatically refresh the attribute value if the underlying data in the database is changed by another user
• B. to automatically lock the corresponding record in the database
• C. to define an attribute that the framework uses to check whether the update is about to happen on underlying stale data in the database
• D. to highlight the attribute in the Ul with a border when the original attribute value has been changed
• E. to fire an entity object custom method as soon as the original attribute value has been changed
