  A. Only PNG-encoded images support aqualityof 100.

  B. You cannot constrain the image width and height whenqualityis set to 100.

  C. Though 100 is an acceptedqualityvalue in MAF, this will be ignored on Android devices.

• Question 82:

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

  B. Switch the services from SOAP protocol to REST protocol.

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

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

  Correct Answer: A

• Question 83:

  Which two methods allow you to update a MAF application without reinstalling the application?

  A. Use the standard customization mechanism provided by JDeveloper and Oracle Metadata Service

  (MDS) to customize AMX application feature artifacts and metadata files.

  B. Use the Configuration Service to configure the end points used by the web services and loginconnections accessed by the MAF application.

  C. Configure the MAF application to accept pushnotifications sent over the Apple Push Notification Service (APNs) and GoogleCloud Messaging (GCM) by the Configuration Service.

  D. Create a new MAF application from an existing one by first packaging the original MAF application as a Mobile Application Archive (.maa) file and then, by deriving a new mobile application from this file.

  E. Retrieve an URL from the end user through the user interface and callAdfmfJavaUtilities.overrideConnectionPropertyto update the end point for a connection.

  Correct Answer: AB

• Question 85:

  You are asked to build an adaptive design into an MAF application. The requirement is to show amultipage 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 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.

  B. 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.

  C. 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.

  D. 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.
