You are debugging an MAF application. The application stores the total cost of items in the user's shopping cart in a managed bean variable. The total cost is then displayed in an AMX page via an amx:outputText component. A button is pressed on the page to add another item to the shopping cart, and, as a result, the total cost value is changed in the managed bean. However, you notice that the value is not changed in the AMX page.
Which is the reason for this behavior?

• A. The total cost variable does not have aPropertyChangeListenerfiring on data change.
• B. The scope of themanaged bean ispageFlowScope.
• C. Theamx:outputText partialTriggerproperty must include the ID of theamx:commandButtonthat is invoking the change.
• D. The variable is anintinstead of adouble.

The content of a collection, exposed by JavaBean data control, is changed programmatically by adding a new object to the collection through Java in response to a command button action.
Which event do you need to raise at the end of the Java call to ensure that the user interface is refreshed to display the changes applied from Java?

• A. oracle.adfmf.java.beans.PropertyChangeSupport propertyChangeSupport =...
  ...
  propertyChangeSupport.firePropertyChange("arrayName", oldValue, newValue);
• B. There is no need to raise an event from Java because the framework will automatically take
  care of propagatingthe change to the UI.
• C. oracle.adfmf.framework.api.AdfmfJavaUtilities.flushDataChangeEvent();
• D. oracle.adfmf.java.beans.ProviderChangeSupport providerChangeSupport =...
  ...
  providerChangeSupport.fireProviderCreate("arrayName", newObjectId,newObject);

Your application has the requirement to create a shopping cart feature with multiple pages to search and select items and separate pages to pay and finalize the transaction.
When defining this feature in MAF, which single content type is the correct choice?

• A. bounded task flow
• B. local AMX
• C. declarative component
• D. fragment
• E. remote task flow
• F. local HTML
• G. remote URL
• H. unbounded task flow

The EL expression #{deviceScope.hardware.networkStatus} returns a dynamic value based on the mobile device's current network connectivity.
Which is an invalid use of the network status?

• A. If the value returned is 3g, warn the user that downloading data may take significant time.
• B. Disable entry to a feature if it requires network access and the current network status isnone.
• C. Call an external web service to refresh data if a connection is available; otherwise, use a local cached copy of the data.
• D. Stop the user from invoking the phone device service, which relies on a 2G, 3G, or 4G connection if the network status returnswifi.

In embedding an Android third-party Cordova Plugin into your MAF application, the plugin may include a /res directory. What is the purpose of this directory?

• A. It contains optional resources required by the plugin at run time such as images, constants, layouts and strings.
• B. It defines a number of Android XML files specifying what device resolutions are supported by the Cordova plugin.
• C. It is a temporary location for build time artifacts.
• D. It contains optional pluggable resources that the plugin consumer can bundle into the Cordova plugin at deployment time.
