Which statement is true about the use of data controls in JSF? (Choose the best answer)

A. Only Oracle ADF Business Components can be exposed as data controls.

B. Dragging a data control onto a JSF page generates a Java class that acts as a managed bean

C. An XXXpagedef xml file holds detailed information about a JSF page's use of data and operations exposed through ADF Data Controls

D. Data controls eliminate the need to use expression language in your JSF code for binding the Ul to data

E. A Databindings cpx file holds names of managed beans that you map to Ul elements

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.

Which three statements are true about using a dvt;map component on a page? (Choose three.)

A. You need to define a connection to a server that provides map images.

B. You can use an exact street address to show a point theme.

C. There is no way to display the distance between two points on a map.

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.

Which two statements describe the characteristics of a view object?

A. it represents a row in the specified database table.

B. it represents an association between two entity objects.

C. it encapsulates a SQL query and simplifies working with data from a database.

D. it allows data to be ordered based on an ORDER clause.

E. it must include every attribute defined in an underlying entity object.

Consider the following code:

At run time, a user modifies the value in the af:inputText control, then presses afcommandButton

Assuming no errors are raised, which option represents the managed bean code invoked in the correct

order1? (Choose the best answer.)

A. myBean handleChange, myBean doAction, myBean.qetDestination

B. myBean.doAction, myBean handleChange, myBean.getDestination

C. myBean.handleChange, myBean.doAction

D. myBean.doAction, myBean.handleChange

Which code sample is the recommended way to override the createQ method in Employeeslmpl, an implementation of oracle.jbo.serverEntitylrnpl for the Employee?

A. protected void create(AttributeList attributeList) { SetAttributelnternal (SALARY, 0); super.create (attributeList); }

B. protected void create(AttributeList attributeList) { super create(attnbuteList), setAttributelntemalC'SALARY", 0);]

C. protected void create(AttributeList attributeList) { super create(attributeList); setSalary(O); }

D. protected void create(Attributel_ist attributeList) { setSalary(O);}
