You are investigating a mobile application that uses SOAP web services that invoke queries on a database to get the data to the mobile UI. The customer complains about the application being too slow.
Which of the following changes would not improve the performance of the application?

• A.  Reduce the number of fields returned from the service so that only the needed fields are returned.
• B.  Switch the services from SOAP protocol to REST protocol.
• C.  Add a layer that fetches the data on the middle tier into a Java class and then expose that class asa SOAP service.
• D.  Introduce middle-tier data caching for data that does not change frequently.

Identify the statement that correctly describes the configurable aspects of a MAF application.

• A.  It is possible to configure the application only through user preferences.
• B.  It is possible to configure the application through user preferences and the end points for web services and login connections can also be configured.
• C.  MAF provides a built-in user interface to change the end points for web services and login connections.
• D.  It is possible to configure an application through user preferences and the Configuration Service, but only if the application relies on the Access Control Service for authorization.

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 transfer'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.  Use RESTFul web services and the JSON data format instead of SOAP/XML web services to communicate with the back end.
• E.  Perform batch inserts or updates to the local SQLite database in multiple concurrent threads.

Which three statements are true about MAF data controls?

• A.  Data controls are configured in one or moreDataControls.dcxfiles.
• B.  Data controls expose data service structures in the data controls panel. The information exposed includes attributes, collections, and public methods.
• C.  MAF is restricted to ten data controls per mobile application.
• D.  A data control is an adapter that exposes a simpler, unified development API for MAF application developers to declaratively and programmatically access data services.
• E.  Data controls in MAF exist for remote SOAP and REST services only and handle all of the XML to Java object marshalling and unmarshalling.

For a MAF application to register an URL scheme to be invoked by other applications on the device, it must define two things. First, it defines the URL scheme in the maf-application.xml file.
What is the second thing the application must do to be invoked and handle the event when the application is initiated by the URL scheme?

• A.  Within the application's LifeCycleListenerImpl.start() method, register an EventListener to fire and respond to the event.
• B.  Include an URL scheme Cordova plugin to respond to the event on each platform.
• C.  In themaf-application.xmlfile, configure the 'Push-Notification' device access privilege.
• D.  In themaf-application.xmlfile, define an event listener with an associated Java class to respond.
