Identify the four correct statements about REST services.

REST may return JSON, XML, or any other MIME type. REST uses HTTP verbs (such as GET, PUT, POST, etc.) to indicate the intent of the REST call. Enterprise systems may be given a REST interface by using the Oracle Service Bus. REST services cannot return binary data. REST services are well-suited to mobile and web clients.

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 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, the first content configured for a Feature holds the single page layout, whereas the second (with no constraints defined) has the multipage wizard function. A Feature LifecycleListener class can be created and configured to load AMX content upon application start. In this case, Java, using the AdfmfContainerUtilitiesframework helper class, determines the type of device to be smartphone tablet and switches the content. Two MAF Features can be created, one for the single page view and the other for the multipage wizard. Constraints defined on the feature configurationconditionally switch between the two options. Selecting the Enable Adaptive Design check box in the maf-application.xml file visual editor allows you to configure constraints on the application level that, uponapplication 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.
