Q21. Which two statements describe the characteristics of an application module? (Choose two)
A. ft provides the database transaction for the queries that it encapsulates.
B. it defines view object instances to implement an application use case.
C. it defines entity object instances to implement an application use case.
D. There is a one-to-one mapping between view objects and application modules.
E. Each ADF application has only one application module.
Answer: A,B
Q22. 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.
Answer: C
Q23. 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.
Answer: A,C,E
Q24. Which two statements are true about the Key Exists validator? (Choose two.)
A. it always issues a select to the database to ensure all data is up to date.
B. it first checks the cache for match and then goes to the database only if necessary.
C. it cannot validate any data changes that happened in the current transaction that have not yet been committed to the database.
D. it can validate any data changes that happened in the current transaction that have not yet been committed to the database.
E. it can be used only with attributes that are defined as primary keys in the database.
Answer: B,D
Q25. 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.
Answer: A,C,D
Q26. 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.
Answer: D
Q27. You need to execute a managed bean function immediately when af:selectBooleanCheckhox is selected by a user. Which listener property would you implement in i
A. valueChanqeListener
B. selectionListener
C. actionListener
D. queryListener
E. phaseListener
Answer: A
Q28. For what purpose would you use the entity object attribute setting Change lndicator?(Choose the best answer.)
A. to highlight the attribute in the Ul with a border when the original attribute value has been changed
B. to fire an entity object custom method as soon as the original attribute value has been changed
C. to automatically lock the corresponding record in the database
D. to automatically refresh the attribute value if the underlying data in the database is changed by another user
E. to define an attribute that the framework uses to check whether the update is about to happen on underlying stale data in the database
Answer: C
Q29. Which method must you override to ensure that messages are logged each time bind variable values are set in an application? (Choose the best answer.)
A. bindParametersForCollection() method in any ViewObjectlmpI that uses bind variables
B. setBindVahables() method in any ViewObjectlmpI that uses bind variables
C. bindParametersForCollectionO method in the super-class of ViewObjectlmpI
D. bindParametersForCollectionO method in the super-class of ApplicationModulelmpI
Answer: C
Q30. What is the first step you perform to secure an ADF application? (Choose the best answer.)
A. Edit the web.xml file and adf-confiq.xml file to include the ADF authentication servlet configuration.
B. Merge the application roles into the deployment server's roles.
C. Define a lifecycle listener to intercept the HTTP request for the application's URL
D. Use the Configure ADF Security wizard to enable secunty for the application.
E. Create a login page and run the application authenticated as the test-all user.
Answer: D
