• Question 1:

  What is the role of Apache Cordova within the Oracle Mobile Application Framework's (MAF) architecture?

  A. It provides the APIs to make calls to external web services.

  B. It contains the JVM run time for executing Java code.

  C. It provides services for connecting to the device's services.

  D. It connects to external Apache web servers.

  E. It generates the source code stubs for your MAF application.

  Correct Answer: C

• Question 2:

  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. Perform batch inserts or updates to the local SQLite database in multiple concurrent threads.

  E. Use RESTFul web services and the JSON data format instead of SOAP/XML web services to communicate with the back end.

  Correct Answer: CD

• Question 3:

  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. oracle.adfmf.framework.api.AdfmfJavaUtilities.flushDataChangeEvent();

  C. oracle.adfmf.java.beans.ProviderChangeSupport providerChangeSupport =... ... providerChangeSupport.fireProviderCreate("arrayName", newObjectId,newObject);

  D. There is no need to raise an event from Java because the framework will automatically take care of propagatingthe change to the UI.

  Correct Answer: A

• Question 4:

  TheDataBindings.cpxfile contains __________.

  A. a mapping of AMX pages to theirpagedef.xmlfiles and the data controls used in the UI layer

  B. a list of all the data controls defined in an application

  C. code to control the order of data control initialization

  D. information about the local SQLite database data used in the application

  E. mapping between individual UI components and the data controls they use

• Question 5:

  In defining anURL scheme for a MAF application, what can the URL payload carry at run time when the event listener captures the URL scheme call?

  A. Only the URL scheme name might be carried. No other URL is valid. For example, it might carry: myapp://

  B. The URL scheme name and optionally ahierarchicalpart might be carried. No other URL is valid. For example, it might carry: myapp:// myapp://doSomething

  C. The URL scheme name and optionally ahierarchicalpart might be carried along with an optional single parameter key-value pair. For example, it might carry: myapp:// myapp://doSomething myapp://doSomething?value1=123

  D. The URL scheme name might be carried along with an optional hierarchical part and multiple parameter key-value pairs. No other URL is valid. For example, it might carry: myapp:// myapp://doSomething myapp://doSomething?value1=123 myapp://doSomething?value1=123andvalue2=true

  Correct Answer: A

• Question 6:

  Which behavior results from this code inside anamx:listItemcomponent?

  A. When someone taps an item in the list, the item is automatically approved.

  B. When someone taps and holdsa list item, a fixed value is set in a variable that will be available in another page in the same task flow.

  C. An exception occurs because this is not a valid use of pageFlowScope variables.

  D. When someone taps and holds a list item, the value of the "approved" variable is evaluated and, if it is "yes", you perform a specific action.

  Correct Answer: D

• Question 7:

  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 anamx:outputTextcomponent. A button is pressed on the pageto 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. The variable is anintinstead of adouble.

  D. Theamx:outputText partialTriggerproperty must include the ID of theamx:commandButtonthat is invoking the change.

  Correct Answer: D

• Question 8:

  Your team created an MAF application. A developer at the application user's site wants to further customize the application to modify the look and feel and to add some features.

  Which type of file should you send to the developer and how would he start using it?

  A. Provide a JAR file containing your Oracle MAF Java code and he will add it as a JAR library to his MAF application.

  B. Provide an Oracle MAF Application Archive file and he will use the Create a new MAF Application from Application Archive option in JDeveloper.

  C. Provide an Oracle MAF Application Archive file and he will add this as another project in his workspace.

  D. Provide an IPA file and he will use Xcode to decompile it and further modify the code.

  Correct Answer: C

• Question 9:

  Which two statements are true about the scope of data control instances in AMX features?

  A. Data control instances have a global scope andcanbe used to share data state across AMX features.

  B. Data control instances have a per AMX feature scope and cannot be used to share data across features.

  C. Data control instances are in an application scope and can be used to share data between featuresof any technology.

  D. Data control instances can be used to share data state between views in a bounded task flow.

  Correct Answer: BD
