Answer: D QUESTION: 77 You have built a mobile application with features X and Y. You have implemented an application level oracle.adfmf.application.LifeCycleListener named AppListener with methods start(), stop(),activate(), and deactivate(). You have also implemented two featurelevel oracle.adfmf.feature.LifeCycleListener classes for features X and Y named XListener and YListener with methods activate() and deactivate().

A user has opened your application and the code is currently executing in feature X. The user then performs the following steps: 1. Suspend the application (put it in the background).

2. Start the application.

3. Open feature Y.

Which option describes the methods and the specific order in which they are invoked when

the user performs these steps?

A. AppListener.stop(), AppListener.start(), YListener.activate()

B. XListener.deactivate(), AppListener.deactivate(),

AppListener.activate(),XListener.activate(), XListener.deactivate(), YListener.activate()

C. XListener.stop(), YListener.activate()

D. XListener.deactivate(), XListener.activate(), XListener.deactivate(), YListener.activate()

Answer: A QUESTION: 78 You are developing the UI pages of your Oracle MAF application and you want the pages to be cross platform-compatible and future-proof from changes to support the updated platforms.

Which is the best content type choice for developing your UI pages in MAF? A. Local HTML B. Local AMX C. Remote URL D. Page Fragment Answer: B QUESTION: 79 You have been asked to select the appropriate security policy to apply to a SOAP web service data control. The web service is accessed over HTTPS. In addition, the web service calls must use the same single sign-on infrastructure as the other web applications deployed on the network. That way, users will not have to authenticate again if they navigate between remote URL features and AMX features making web service calls. Which policy would you choose?

A. oracle/wss_http_token_over_ssl_client_policy B. oracle/wss_username_token_client_policy C. oracle/soap_over_ssl_client_policy D. oracle/wss11_message_protection_client_policy Answer: A QUESTION: 80

A. Discover and download mobile applications from an enterprise app store.

30

B. Encrypt the local database and files on the device.

C. Display the user ID and password in a log file for debugging purposes.

D. Enforce a data leak protection policy such as disabling copy-paste in the application.

E. Hide UI fields that contain data not authorized by the logged-in user.

Answer: A, B, D QUESTION: 82 You have built a MAF application to manage service calls. The end users are company employees that are deployed in the field and they must document the work they perform. To do this, they must take high-resolution pictures of the equipment before and after repairs.

Which two strategies should you use to ensure that the application is optimized for performance while keeping the memory usage at a reasonable level?

A. Store the picturesin the local SQLite database or on the file system and transmit them to the server by starting a background thread only when a wi-fi network connection is available.

B. Transmit each picture right away over a cellular data connection and inform the user of the transferâ&#x20AC;&#x2122;s progress through visual indicators.

C. Always bind AMX pages directly to the Web Service DataControl and never invoke web services through a POJO Data Control.

D. Perform batch inserts or updates to the local SQLite database in multiple concurrent threads.

E. Use RESTFul web services and the JSON data format instead of SOAP/XML web services to communicate with the back end.

Answer: C, D QUESTION: 83 How does the REST data control wizard map REST web service resource URIs to HTTP method calls in MAF? A. Upon configuring REST service access, the application developer manually configures the REST URIs and maps them to HTTP methods.

B. Stepping through the REST service data control wizard, the application developer references a remote Web Application Description Language (WADL) file that provides the service URIs and associated HTTP methods from which the developer can choose.

C. The REST service data control creates only the REST connection and then generates the datacontrol definition. To configure the REST service URIs and map them to HTTP methods, the application developer needs to edit the Data Control definition file.

D. The REST service data control maps the REST URI according to the annotations in the REST service. No user action is required.
