Which two statements are true about af:tree? (Choose two.)

• A.You can show only one outputText per node in aftree.
• B.To modify the data fields shown in a node of a tree created with ADF binding, you need to edit the tree bindings.
• C.Trees can display, at the most, a three-level-deep hierarchy.
• D.You can specify a filter for a tree's node based on an attribute value at design time.

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

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

• A.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
• B.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
• C.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
• D.None; they are used interchangeably.
• E.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

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="#{emp.lastName}e
• B.to="#{pageFlowScope emp LastName}"
• C.to="#{lastName}"
• D.to="#{pageFlowScope.emp.lastName):
• E.to^frfpageFlowScopeEmplastName}"
• F.to="#{LastNamer

Which option represents the expression you would use to determine if a user belongs to the administrator role? (Choose the best answer.)

• B.adf.context.secuhtyContext.userlnRole.administrator
• C.#{securityContext.userinRolefadministrator']}
• D.sfadfSecurity.userlnRolefadministrator']}
• E.#{securityContextuserGrantedResource [administrator1]}
