（A）Switch the services from SOAP protocol to REST protocol.

（B）Add a layer that fetches the data on the middle tier into a Java class and then expose that class asa SOAP service.

（C）Reduce the number of fields returned from the service so that only the needed fields are returned.

（D）Introduce middle-tier data caching for data that does not change frequently.

（A）When a MAF application is configured to use the Configuration Service, it displays an Oracle-provided dialog at startup where the user must enter a user name, a password, and the URL to theConfiguration Server.

（B）The Configuration Service is a custom RESTFul web service that you must implement yourself according to a specification provided by Oracle.

（C）MAF provides a set of APIs within theoracle.adfmf.config.client.ConfigurationServiceclass that allows you to check for new changes on the server and downloadupdates to an application's configuration.

（D）The Configuration Server is provided by the Oracle Mobile Cloud Service and cannot be deployed on your own servers.

（A）Dependent data collections need to be shown on a page in which selecting a row in the parent collection triggers the query and display of remote detail data.

（B）Data read from remote servicesshould be cached on the client for best performance.

（C）The mobile application must implement a local read-write strategy in which all data is first read from and written to the mobile client persistent store.

（D）For best performance, a user must be able to sort dataqueried from a remote servicelocally in the mobile application.

（E）Data that is created or changed in the mobile application must immediately update the remote service on the server.

（A）It does not need to be defined ahead of time because you can call it in your code.

（B）Define it in theadfc-mobile-config.xmlfile.

（C）Define it in a taskflow's XML definition file.

（D）Add annotation injection in the Java class.

（A）It creates a separate container for corporate applications on a mobile device.

（B）It wipes data from a lost or stolen device.

（C）It modifies service endpoints to allow for changing authentication protocols.

（D）It integrates heterogeneous services across a network.

（B）<amx:commandButton rendered="#{device.camera}"/>

（C）<amx:commandButton rendered="#{deviceScope.device.hasCamera}"/>

（D）<amx:commandButton rendered="#{deviceScope.camera}"/>

（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）help the service designer specify the service interface

（C）thoroughly consider the ergonomics of the application to make it easy and intuitive to use

（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
