2 Exam A QUESTION 1 Which three statements are true about the default value for an entity object attribute? (Choose three.) A. It can be a literal value. B. It can be defined by a Groovy expression. C. It can be defined by a SQL select statement. D. It can be defined by an Expression Language (EL) statement. E. It can be defined by referencing a database stored procedure. Correct Answer: ABD /Reference: A: The Value field (in the Edit Attribute dialog) allows you to specify a static default value for the attribute when the Value Type is set to Literal. For example, you can set the default value of the ServiceRequest entity object's Status attribute to Open, or set the default value of the User entity object's UserRole attribute to user. B: You can use a Groovy expression to define a default value for an attribute. This approach is useful if you want to be able to change default values at runtime. D: Groovy scripting logic is similar to Expression Language (EL) References: QUESTION 2 A backing bean for a page must hold its value over multiple requests for the current user. Which three bean scopes are applicable? (Choose three.) A. requestscope B. backingbeanscope C. viewscope

3 D. pageflowscope E. sessionscope F. applicationscope Correct Answer: CDE /Reference: C: View scope: The object is available until the view ID for the current view activity changes. This becomes handy when you use partial page rendering. If you have a dependent list box, you might send a server request to refresh the list box. When a response is returned, the request scope will be gone but the view scope will be still there. D: A pageflow scope exists for each task flow instance and has a lifespan between request and session scope. The lifetime of the scope spans across all pages in a bounded task flow. E: Session scope: The object is available for the duration of the session, which is user instance-specific. A use case for a session scope bean is a user info bean that stores information about a user, which is read from the database or an LDAP server, to avoid unnecessary queries. Incorrect Answers: A: Request scope: The object is available from the time an HTTP request is made until a response is sent back to the client. From another perspective, a request scope starts with a request to be issued from one view to another for navigation cases that don't perform a redirect but a default server-side forward. The scope spans across all non-view activities that follow the view of interest to the next view activity. B: The backing bean scope is comparable to the request scope, with the difference in that it exists for a specific client component. In general, all managed beans used in reusable components should be configured to backingbean scope. For example, bounded task flows that are designed to be regions on a page should use the backingbean scope if more than one instance of the task flow is expected to be on a single page. F: Application scope: An application scope object is available for the duration of the application and is shared among users. This scope may be used to hold static objects that are the same for all users. References: QUESTION 3 Identify three statements that are true about JSF. (Choose three.) A. Components are used to define page structure. B. Navigation between pages is defined outside of the JSF page in the metadata. C. Managed beans can have only one of two memory scopes. D. Managed beans can be accessed from more than one page.

4 E. JSF does not support template creation for pages. Correct Answer: ABD /Reference: Incorrect: Not C: Managed beans can have the following scopes: Application, session, PageFlow, view, request, BackingBean. Not E: JavaServer Faces (JSF) technology provides the tools to implement user interfaces that are easy to extend and reuse. Templating is a useful Facelets feature that allows you to create a page that will act as the base, or template, for the other pages in an application. By using templates, you can reuse code and avoid recreating similarly constructed pages. Templating also helps in maintaining a standard look and feel in an application with a large number of pages. References: QUESTION 4 Consider the following code: At run time, a user modifies the value in the af:inputtext control, then presses af:commandbutton. Assuming no errors are raised, which option represents the managed bean code invoked in the correct order? (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 Correct Answer: C /Reference: QUESTION 5

5 Which three options does an entity object automatically implement? (Choose three.) A. primary key functionality based on any column in the database that is marked as a primary key B. not-null functionality based on any column in the database that is marked as not null C. attribute precision based on column size D. all table check constraints E. any table triggers Correct Answer: ABC /Reference: When you create an entity object from an existing table, first JDeveloper interrogates the data dictionary to infer the following information: The primary and unique key attributes The mandatory flag on attributes, based on NOT NULL constraints The length and precision of each attribute The Java-friendly entity attribute names from the names of the table's columns (for example, USER_ID -> UserId) The SQL and Java data types of each attribute based on those of the underlying column The relationships between the new entity object and other entities based on foreign key constraints References: QUESTION 6 You create a new ADF Faces page called emp.jsрх and bind some data controls to that page. You notice a file called emppagedef.xml. What is this file for? (Choose the best answer.) A. It is the page definition that contains the XML representation of the page layout and the components on that page. B. It is a template file into which you can write any managed bean code. C. It is the page template definition file that represents the chosen quick start layout. D. It is the file that contains the definition of the bindings to your data-bound components. E. It defines the binding context for all pages in your application. Correct Answer: D /Reference: The pagenamepagedef.xml files are created each time you insert a databound component into a web page using the Data Controls Palette or Structure window.

6 These XML files define the Oracle ADF binding container for each web page in the application. The binding container provides access to the bindings within the page. You will have one XML file for each databound web page. References: QUESTION 7 Which three steps would you perform to enable security for an ADF application? (Choose three.) A. Define authentication and authorization by using the configure ADF Security wizard. B. Define which HTML pages must be secured. C. Grant roles access rights to bounded task flows. D. Grant roles access rights to unbounded task flows. 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 /Reference: A: The Configure ADF Security wizard allows you to choose to enable authentication and authorization separately. C: ADF bounded task flow protects the entry point to the task flow, which in turn controls the user's access to the pages contained by the flow. B: To grant public access to ADF security-aware resources: 1. From the Application menu, choose Secure > Resource Grants. 2. In the Resource Grants page of the jazn-data.xml file overview editor, select one of the following resources from the Resource Types dropdown list: Task Flow when you want to make a bounded task flow public. The application displays the web pages under the permission you define for the task flow itself. Thus, all constituent web pages of the bounded task flow will become public. Web Page when you want to make individual web pages public. Typically, these pages are defined by an unbounded task flow and are top-level pages in the application, such as a home page. Incorrect Answers: D, F: The unbounded task flow is not an ADF security-aware component and allows no grants. References: QUESTION 8 Which statement is true about the difference between an Action binding and a methodaction binding? (Choose the best answer.)

7 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 bind only to a method in a backing bean. C. Both are bindings to methods defined in a business service, but an Action binding is used to bind to a UI component whereas a methodaction binding is only called programmatically from a backing bean. D. Both are bindings to methods defined in a business service, but a methodaction binding is used to bind to a UI control whereas an Action binding is only called programmatically from a backing bean. 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 methods in the data control. Correct Answer: E /Reference: Action binding object can be used to bind command components, such as buttons or links, to built-in data control operations (such as Commit or Rollback) or to built-in collection-level operations (such as Create, Delete, Next, Previous, or ExecuteWithParams). Method bindings are similar to action bindings. But, they are used to bind to methods defined in an ADF BC application, view object, or view row client interfaces. References: QUESTION 9 You are prototyping an ADF application that uses ADF Business Components. However, the database schema that you can connect to does not contain any tables or data to show in the prototype. Which two declarative options are available to you to provide hard-coded data for the purposes of your prototype? (Choose two.) A. entity objects with default values B. placeholder data control C. static list view objects D. declarative managed beans Correct Answer: BC /Reference: B: Placeholder data controls are easy-to-create, yet fully functional, stand-in data controls that can efficiently speed up the design-development process. UI designers can use placeholder data controls to create page layouts and page flows without the need to have real data controls available.

8 C: The key advantage of the Static List View Object is it's suitable for small datasets that never change. Static List VOs suitable for stub VOs in creating ADF Faces RC web page mockups for demonstration purposes, where the database tables have yet to be designed. References: QUESTION 10 View the Exhibit. Which two modifications would you make in the task flow so that RegisterRouter displays the appropriate page depending on the user type and subsequently displays the confirmation page? (Choose two.) A. Define the iscustomer outcome in RegisterRouter. B. Create a global control flow rule pointing to CustomerPage. C. Create a control flow rule from EmployeePaqe to Confirmation. D. Change the default activity from Register to RegisterRouter. E. Set the isemployee outcome to #{FALSE}. Correct Answer: AB

9 /Reference: QUESTION 11 You create a default view object based on the Employees entity, using the wizard and accepting the default settings. Which option represents the source file(s) that are typically created for you? (Choose the best answer.) A. EmployeesView.xml B. EmployeesViewImpl.java C. EmployeesViewRowImpl.java D. EmployeesView.sql E. EmployeesView.xml and EmployeesViewImpl.java Correct Answer: A /Reference: What Happens When You Create an Entity-Based View Object When you create an entity-based view object, JDeveloper creates the XML component definition file that represents the view object's declarative settings and saves it in the directory that corresponds to the name of its package. For example, if the view object was named StaffList in the devguide.model.queries package, so the XML file created will be./devguide/model/queries/stafflist.xml under the project's source path. This XML file contains the information about the SQL query, the name of the entity usage, and the properties of each attribute. If you're curious to see its contents, you can see the XML file for the view object by selecting the view object in the Application Navigator and looking in the corresponding Sources folder in the Structure Window. Double-clicking on the StaffList.xml node will open the XML in an editor so you can inspect it. References: QUESTION 12 Which two statements describe the characteristics of an entity object? (Choose two.) A. An entity object represents a cache for records retrieved from the database.

10 B. An entity object includes an ORDER clause to allow you to order the data in it. C. An entity object includes a WHERE clause to allow you to shape the data in it. D. Every column in a database table must be represented as an entity object attribute. E. An entity object definition is described in XML. Correct Answer: AD /Reference: A: An entity object caches data from a database and provides an object-oriented representation of it. D: When you use a Business Components for Java wizard to create entity objects from existing tables, each database table becomes an entity object. Each column in the database table becomes an entity object attribute, which can have the same name as the column or a different name that is more meaningful to your business application. References: QUESTION 13 Which three options are available in the ADF Controller that are not available in the generic JSF 2.0 controller layer? (Choose three.) A. pageflow scope: a memory scope for managed beans that is available for several pages (longer than a request scope and shorter than a session scope) B. ability to break the page flow of an application into multiple files C. subflows that can be included as regions inside a page D. method calls as part of the definition of a page flow E. defining managed beans that contain references to components on a page Correct Answer: ACE /Reference: A: ADF Memory scopes There are 6 types of memory scopes 3 from standard JSF application 1) Application Scope 2) Session scope 3) Request scope In addition to above ADF Faces provides the following 4) PageFlowScope 5) BackingBeanscope 6) ViewScope C: There is no such thing as subflows in JSF, but they do exist in ADF.

11 E: Backing bean scope: Special case of request scope Associated with a specific manage bean instance Used with declarative components, regions and page fragments that use a managed bean to hold view state information Allows multiple instances of the components to co-exists on a single page Use this scope if it is possible that your task flow appears in two ADF regions on the same JSF page and you want to isolate each instance of ADF region References: QUESTION 14 Which two options represent techniques that you would use together to deploy an ADF application? (Choose two.) A. Deploy an EAR file by using Enterprise Manager. B. Create an EAR deployment profile in JDeveloper. C. Deploy a WAR file by using Ant or ojdeploy. D. Create a JAR deployment profile for a shared library in JDeveloper. E. Deploy a WAR file by using Enterprise Manager. Correct Answer: AB /Reference: A: Deploying ADF Applications You can use Oracle Enterprise Manager Fusion Middleware Control to deploy the EAR file created in JDeveloper. B: Deploying ADF Applications During application development using JDeveloper, developers can test the application using the Integrated WebLogic Server that is built into the JDeveloper installation, or they can use JDeveloper to directly deploy to a standalone application server. Incorrect Answers: C, E: For ADF applications, WAR and MAR files can be deployed only as part of an EAR file. References: QUESTION 15 Identify two statements that describe the benefits of using ADF to build web applications for mobile devices. (Choose two.) A. Mobile devices are supported by using native code.

12 B. ADF code and applications are re-used. C. Separate applications are required for tablets and smart phones. D. ADF Faces components adjust to support touch gestures and layouts. E. Native mobile components are used to develop a user interface. Correct Answer: BD /Reference: B: Oracle ADF Mobile enables developers to build and extend enterprise applications for ios and Android from a single code base. D: ADF Faces include Tablet/Touch Gesture Support. Incorrect Answers: A: Java code, not native code, is used. Oracle ADF Mobile enables developers to build and extend enterprise applications for ios and Android from a single code base. References: QUESTION 16 View the Exhibit

13 A user interface requires a view of data for a customer order to include information about the order, items in the order, and information about the customer who placed the order. The application entities and their relationships are defined as shown in the Exhibit. Which two steps would you perform to meet this requirement? (Choose two.) A. Create a default view object based on OrdEO, and add ItemEO and CustomerEO as reference entities to the view object. B. Create default view objects based on OrdEO, ItemEO, and CustomerEO, and create view links based on the defined associations.

14 C. Create a view object based on SQL and define the SQL to select from the Ord, Item and Customer database tables. D. Add attributes from the ItemEO and CustomerEO entities as needed. E. Create calculated attributes as needed from the Order, Item, and Customer database tables. F. Set the ItemEO and CustomerEO attributes to updatable=never. Correct Answer: BD /Reference: B: Oracle ADF view links are business components that define a relationship between two Oracle ADF view object definitions (the "source" and "destination" view objects) based on sets of view attributes (the "source" and "destination" attributes) from each. These can range from simple one-to-many relationships to complex many-to-many relationships. This allows you to easily create master/detail relationships between data controls in the client. Reference: QUESTION 17 Consider the validation code in a Shipping entity object that is designed to ensure that the date ordered is <= the date shipped. public boolean validatedateshippedafterdateordered() { Date DateShipped = getdateshipped(); Date DateOrdered = qetdateordered(); if (DateShipped!= null && DateShipped.compareTo(DateOrdered) < 0) { return false; } return true; } Which entity object validation rule should you integrate this with? (Choose the best answer.) A. compare validator on the DateShipped attribute B. method validator on the DateShipped attribute C. compare validator on the DateOrdered attribute D. range validator on the Shipping entity object E. method validator on the Shipping entity object Correct Answer: C

15 /Reference: If the validity of one attribute is dependent on one or more other attributes, enforce this rule using entity validation, not attribute validation. Examples of when you would want to do this include the following: You have a Compare validator that compares one attribute to another. You have an attribute with an expression validator that examines the value in another attribute to control branching in the expression to validate the attribute differently depending on the value in this other attribute. You make use of conditional execution, and your precondition expression involves an attribute other than the one that you are validating. References: QUESTION 18 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.

16 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 /Reference: QUESTION 19 You create a default entity object based on the Employees table, using the wizard and accepting the default settings. Which option represents the source file(s) that are typically created for you? (Choose the best answer.) A. Employees.xml B. Employees.xml and EmployeesImpl.java C. Employees.xml and Employees.sql D. EmployeesDefImp.java E. EmployeesDefImpl.xml Correct Answer: A /Reference: JDeveloper creates the XML component definition file that represents its declarative settings and saves it in the directory that corresponds to the name of its package. For example, if one of the entities created above was named User in the devguide.model.entities package, so the XML file created will be./devguide/ model/entities/user.xml under the project's source path. References: QUESTION 20 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 ViewObjectImpl that uses bind variables B. setbindvariables() method in any ViewObjectImpl that uses bind variables C. bindparametersforcollection() method in the super-class of ViewObjectImpl D. bindparametersforcollection() method in the super-class of ApplicationModuleImpl

17 Correct Answer: C /Reference: References: QUESTION 21 When you manually create a binding such as an attribute value binding, what name would you give to the binding? (Choose the best answer.) A. a name that reflects the UI component to which it is bound B. the page name suffixed with the UI component name to which it is bound C. the page name suffixed with the data control name D. the name of the data control attribute to which the binding refers E. an EL (Expression Language) of the form #{bindings.<datacontrolname>.value} Correct Answer: B /Reference: Note: The oracle.jbo.uicli.binding.juctrlvaluebinding class implements the attribute value binding. The attribute value binding permits the databound UI component to obtain the attribute value of the specified collection's data object. Depending on the type of UI component, users may view and, in some cases, edit the value of the attribute. The attribute value binding defines its own set of runtime properties. References: QUESTION 22 Which two statements are true about the Key Exists validator? (Choose two.)

18 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. Correct Answer: BD /Reference: The Key Exists Validator is validator that can be defined at either the entity level or the attribute level but pertains to an entity object attribute to check whether a key exists based on a primary key, foreign key or an alternate key. The Key Exists validator will check first the cache querying rows not committed yet to the database and if the key is not found in the cache will run a check in the database. References: QUESTION 23 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 UI 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 /Reference: Application modules can contain service methods--methods that perform complex operations on data. These methods can be called from clients, requiring very little data manipulation processing in the client itself. Service methods are implemented in an application module's class, and exposed on tier-independent interfaces that allow clients to access the application module consistently, whether it is deployed locally or as an EJB session bean. Inside the service method, you can do any of the following: Dynamically add view object and view link instances to the data model Remove view object and view link instances from the data model Find view object instances and perform operations on their row sets

Which listener property would you implement in af:selectbooleancheckbox to achieve this? (Choose the best answer.) A. valuechanqelistener B. selectionlistener C. actionlistener D. querylistener E. phaselistener Correct Answer: A /Reference: The value ChangeListener attribute is a method reference to a value change listener. References: QUESTION 25 Which two statements are true about af:tree? (Choose two.) A. You can show only one outputtext per node in af:tree. 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. You can specify a filter for a tree s node based on an attribute value at design time. D. Trees can display, at the most, a three-level-deep hierarchy. Correct Answer: AC /Reference: References:

20 QUESTION 26 Which statement is true about the role of data controls in ADF? (Choose the best answer.) A. They implement business service functions. B. They persist data from the database for display in the user interface. C. They provide a consistent abstraction over the implementation details of a business service. D. They are a Java API that is called directly from each UI component to populate the component with data. E. They are the primary source of validation logic to control the behavior of your business service. Correct Answer: C /Reference: Once you have created your business services, you create the data controls that use metadata interfaces to abstract the implementation of those services and describe their operations and data collections, including information about the properties, methods, and types involved. References: QUESTION 27 Which two statements are true about attribute value bindings? (Choose two.) A. Multiple UI 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 attribute can have only one attribute value binding. D. An ADF Faces inputtext and an outputtext component displaying the same attribute value would typically use separate bindings. E. Creating an attribute value binding by dragging and dropping from the Data Controls window references, by default, an attribute value in the current row in the collection. Correct Answer: CD /Reference: QUESTION 28 Which two statements are true about an af:panelstretchlayout component? (Choose two.)

21 A. A component placed in the center facet dynamically spaces out vertically to fill out the page height. B. If the top facet has more content then fits vertically, it automatically adds a vertical scroll bar. C. Facets without content in them do not show up at run time. D. Components placed in the center facet stretch to fill the horizontal space regardless of their containing layout container. E. You cannot include another panelstretchlayout component in the bottom facet. F. You can specify the vertical size for the top facet in pixels. Correct Answer: AB /Reference: A: The panelstretchlayout component stretches the child in the center facet to fill all of available space. The available space may be constrained by the presence of other children in the top/bottom/start/end facets. When these children are present, they occupy space defined by the topheight/bottomheight and startwidth/ endwidth attributes. Incorrect Answers: E: Examples of child components that can be stretched inside of the panelstretchlayout facets include <af:panelstretchlayout>.

24 QUESTION 34 View the Exhibit. How would you implement functionality to display product details in a separate window when users place their cursors over a link in the table? (Choose the best answer.) A. Create detail components in an af:popup component. Add af:showpopupbehavior to the link within the table and set the PopupId to the ID of the pop-up component. Set the triggertype property on the pop-up to mousehover. B. Create detail components in an af:dialog component. Add af:showpopupbehavior to the link within the table and set the PopupId to the ID of the dialog component. Set the triqgertype property on the dialog to mousehover. C. Create detail components in an af:popup component. Add af:showpopupbehavior to the link within the table and set the PopupId to the ID of the pop-up component. Set the triggertype property on showpopupbehavior to mousehover. D. Create detail components in an af:panelform component. Add af:showpopupbehavior to the link within the table and set the PopupId to the ID of the panelform component. Set the triggertype property on showpopupbehavior to mousehover.

25 E. Create detail components in an af:dialog component. Add af:clientattribute elements to the link within the table. Create af:setpropertylistener components to pass the currently hovered row's attributes to client components. Correct Answer: C /Reference: The af:showpopupbehavior tag is a declarative way to show a af:popup in response to a client-side event. The client event is specified using the triggertype attribute. The "action" event is the default triggertype if one is not provided. When the showpopupbehavior tag is associated with a component, the popup specified via the popupid attribute will automatically be shown when the associated client event is activated. This tag only acts on client events similar to the af:clientlistener tag. This example will show the popup with the id "somepopup" when the button is clicked. <af:commandbutton id="button" text="click me"> <af:showpopupbehavior popupid="somepopup" alignid="button" align="endbefore" triggertype="action" /> </af:commandbutton> References: QUESTION 35 Which two occur when a bounded task flow is created as a region on a page?

Which statement is true at run time about the ADF Business Component application module? (Choose the best answer.) A. An application module is automatically instantiated for each user session and allocated to that user for the life of their session. B. The programmer must instantiate an application module in a JSF managed bean and carry the application module for the life of the user session. C. One application module bean is instantiated and shared by all user sessions. D. An application module instance is checked out of the application module pool and given to the user session for at least that request, or longer depending on the system load. Correct Answer: A /Reference: The application module is the "work unit" container that includes instances of the reusable view objects required for the use case in question, related through metadata to the underlying entity objects in your reusable business domain layer whose information the use case is presenting or modifying. Your application module works with a Transaction object that acquires a database connection and coordinates saving or rolling back changes made to entity objects. The related Session object provides runtime information about the current application user. References: QUESTION 37 Consider a case where an application does not respond as predicted when a user submits data. Where would you set a breakpoint to debug the issue? (Choose the best answer.) A. the value binding for the iterator on the pagedef for the view B. a view activity that is used to determine where to send the user C. the partialtriggers property of the data bound component in the view D. the Apply Request Values phase of the life cycle

27 Correct Answer: A /Reference: You can add breakpoints to page definition executables and bindings in the page definition editor by selecting a binding or executable item and using the context menu to toggle or disable 'before' or 'after' breakpoints on that item. After the application pauses at the breakpoint, you can view the runtime structure of the objects as well as a list of data for a selected object in the ADF Structure and Data window. Example: To set and use ADF page definition breakpoints: In the page definition editor, in the Outline section, right-click the binding or executable you want to set the breakpoint on. From the context menu, select Toggle Breakpoint Before or Toggle Breakpoint After or both depending on where you want to place the breakpoint. A blue triangle appears on the item indicating that the breakpoint has been set. References:

28 QUESTION 38 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 implementations of business services. 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 flows. Correct Answer: C /Reference: The Role of Oracle ADF for J2EE Applications JDeveloper includes an integrated J2EE runtime framework known as Oracle Application Development Framework (Oracle ADF). Oracle ADF increases the cooperation between the MVC layers both in the design time and the runtime and, importantly, eases the incorporation of complex business services into the application model layer. Specifically, ADF provides these benefits to J2EE application development: * Provides a thin model layer that adapts diverse business services, thus permitting views to be created in a similar fashion, independent of their data source / Model layer - A thin model layer that adapts and combines a full range of business services as desired, including Oracle ADF Business Components, Oracle TopLink mappings, JavaBeans, Enterprise JavaBeans, and web services. * Optionally, provides transaction control support to the model layer and permits web applications to scale better * Cooperates with the highly visual design tools in the JDeveloper IDE and enables an integrated view of the entire J2EE application project References: QUESTION 39 To deploy an application, select the application drop-down and choose Deploy. In the resulting dialog box, select Deploy to EAR file to or Deploy to Application Server to. (Choose the best answer.) A. create a file to deploy to using WLST or Ant scripts; deploy an application to a managed server

29 B. deploy an application to a predefined application server; deploy a JAR file to a predefined application server C. create a file to deploy to a clustered server; deploy an application to a third-party application server D. deploy to the Integrated WebLogic server; deploy to a clustered server E. create a file to deploy to a clustered server; deploy an application using Enterprise Manager Correct Answer: A /Reference: Part 1: You can also use the deployment profile to create an archive file (EAR file). You can then deploy the archive file using Enterprise Manager, WLST, or the Oracle WebLogic Server Administration Console. You can deploy to most application servers from JDeveloper, or use tools provided by the application server vendor. You may also use Ant to package and deploy applications. Part 2: How to Deploy the Application Using JDeveloper After you have created an application server connection and an EAR deployment profile, you can deploy the application to a standalone application server. To deploy an application: 1. Deploy your project to the application server: a. In the Application Navigator, right-click your application and choose Deploy > deployment profile. b. In the Deploy wizard Deployment Action page, select Deploy to Application Server and click Next. Etc. References: QUESTION 40 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

30 view object instance in the Application Module Editor. B. Override each view object's ViewObjectImpl 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 ViewObjectImpl 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. Correct Answer: C /Reference: QUESTION 41 View the Exhibit. What does the SetCurrentRowWithKey activity do for this task flow? (Choose the best answer.) A. calls a method B. calls the updatecustomer page

31 C. determines whether the user is navigated to the updatecustomer or callemployeetf activity D. displays a pop-up that allows the user to enter a value for the current row Correct Answer: B /Reference: QUESTION 42 You have three application modules: A, B, and C. Application modules В and С are nested under the root application module A. Which statement is true when committing the nested application module B? (Choose the best answer.) A. No view objects are committed. B. Only changes to view objects exposed through application module В are committed. C. Only changes to view objects exposed through application modules A and В are committed. D. All changes to all view objects exposed through all application modules A, B, and C are committed. Correct Answer: C /Reference: QUESTION 43 What is the purpose of applying a view criteria to a list accessor (that defines the data source of a list of values)? (Choose the best answer.) A. It allows the data in the list to be filtered based on the view criteria. B. Defining a view criteria allows you to specify different UI options for the list of values. C. It automatically gives end users a search panel from which they can filter the data in the list of values. D. It defines the order in which the data in the list appears. E. It automatically prevents excessively long lists of values by forcing the application of view criteria if the list of values has more than a defined number of rows returned. Correct Answer: A

32 /Reference: In an ADF application a view accessor is considered as an approach to access a view object from another view object or entity object. The view accessors are mostly used to provide result sets for the lists of values. A view criteria you define lets you specify filter information for the rows of a view object collection. The view criteria object is a row set of one or more view criteria rows, whose attributes mirror those in the view object. The view criteria definition comprises query conditions that augment the WHERE clause of the target view object. Query conditions that you specify apply to the individual attributes of the target view obje References: QUESTION 44 Which two components allow you to divide your page into two sections, where one section can be collapsed and expanded by the user, without the need to code logic in a backing bean? (Choose two.) A. af:panelborderlayout B. af:panelsplitter C. af:stretchlayout D. af:paneldrawer E. af:paneltabbed Correct Answer: AB /Reference: A: The panelborderlayout component is a layout element which lays out all of its children consecutively in its middle, and supports twelve other facets: top, bottom, left, right, start and end. Clients should use only one of left/right or start/end for each side, in any one container, but if both are used, left/right "wins". Left, InnerLeft/ Right InnerRight always means left/right regardless of LTR or RTL. Start, InnerStart/End, InnerEnd will respect bidi setting. B: PanelSplitters are used to divide a region into two parts with a repositionable divider. The two parts are identified as the "first" facet and the "second" facet. If the contained component supports it, the contents of a section will stretch to fill up all available space in that section. The panel splitter can be adjusted with the mouse, by pressing a collapse button, or by use of the arrow keys when the splitter is selected. Incorrect Answres: C: The panelstretchlayout component stretches the child in the center facet to fill all of available space. The available space may be constrained by the presence of other children in the top/bottom/start/end facets. D: The paneldrawer control can be used to display a group of showdetailitems. Drawer "handles", aka tabs, represent the showdetailitem children. Selecting a tab/ handle opens the drawer and displays the associated showdetailitem. E: The paneltabbed control can be used to display a group of contents that belongs to a showdetailitem. Tab bar(s) with tabs representing the showdetailitem
