You are asked to build an adaptive design into an MAF application. The requirement is to show a multipage wizard for an MAF application functionality when the application runs on a smartphone and a single page layout for the same functionality when the application runs on a tablet.
Which two options allow you to implement this use case?

• A.A Feature LifecycleListener class can be created and configured to load AMX content upon application start. In this case, Java, using the AdfmfContainerUtilities framework helper class, determines the type of device to be smartphone tablet and switches the content.
• B.Selecting the Enable Adaptive Design check box in themaf-application.xmlfile visual editor allows you to configure constraints on the application level that, upon application start, tell the framework which MAF Features to load when the application is started on a smartphone and which Features to load when the application is started on a tablet.
• C.A Feature can have multiple contents (AMX pages, AMX Task Flow, and so on). A content constraint can be defined on the first content to hide when the application runs on a smartphone and to show when it runs on a tablet. This way, thefirst content configured for a Feature holds the single page layout, whereas the second (with no constraints defined) has the multipage wizard function.
• D.Two MAF Features can be created, one for the single page view and the other for the multipage wizard. Constraints defined on the feature configuration conditionally switch between the two options.

You are debugging an MAF application. The application stores the total cost of items in the user's shopping cart in a managed bean variable. The total cost is then displayed in an AMX page via an amx:outputText component. A button is pressed on the page to add another item to the shopping cart, and, as a result, the total cost value is changed in the managed bean. However, you notice that the value is not changed in the AMX page.
Which is the reason for this behavior?

• A.Theamx:outputText partialTriggerproperty must include the ID of theamx:commandButtonthat is invoking the change.
• B.The total cost variable does not have aPropertyChangeListenerfiring on data change.
• C.The variable is anintinstead of adouble.
• D.The scope of themanaged bean ispageFlowScope.

You and your colleague develop different parts of the same MAF application. He recently joined the company and needs to set up his workstation and devices for debugging. The application needs to be tested on Apple iPads and various Android-powered tablets. Your colleague has been assigned an Apple MacBook Pro as his workstation.
Which three tasks must you perform to ensure that your colleague will be able to debug the application on iOS and Android devices?

• A.Establish a Bluetooth link between your colleague's workstation and the devices.
• B.Obtain a debug signing certificate from the Google Play store developer support.
• C.Make sure that the network device access option is enabled in themaf-application.xmlfile.
• D.Check that the settings in the Mobile Run configuration match those found in thecvm.propertiesfile.
• E.Disable USB debugging on all the Android devices involved because this will interfere the IDE's debugger.
• F.Register any Apple device involved in testing and debugging under the appropriate Apple Developer account.

Service mediation is defined as a(n) _____________.

• A.technique that loosely couples programming languages
• B.product that automatically provides for abstraction between service consumers and service providers
• C.architecture that mediates between the service consumers and one or more service providers in a manner that loosely couples location, interface, data, and security
• D.methodology for mediating between interfaces and concrete instances

Which three roles or activities are commonly performed by mobile application developers?

• A.evaluate how the mobile app will interact with the back-end services and design the application with caching and battery life in mind
• B.thoroughly consider the ergonomics of the application to make it easy and intuitive to use
• C.help the service designer specify the service interface
• D.select the back-end service technologies for the OS, implementation language, and database
• E.specify the scaling of the back-end services for optimal performance
