• Question 33:

  Which step would you perform to declaratively bind data collections and attributes, saved in a local SQLite database, to AMX user interface components?

  A. Configure the SQLite database data control and use the data controls panel to drag and drop data collections and attributes onto the AMX view.

  B. Use a JavaBean to wrap calls to SQLite database and create a JavaBean DataControlfrom it, that then appears in the data controls panel.

  C. Use the REST service adapter to query data from SQLite in JSON format.

  D. Create a TopLink persistence layer to query and update the database. The AMX user interface components bind to the EJB session facade.

  Correct Answer: B

• Question 34:

  You have built a mobile application with features X and Y. You have implemented an application leveloracle.adfmf.application.LifeCycleListenernamed AppListener with methodsstart(), stop(),activate (),anddeactivate(). You have also implemented two featureleveloracle.adfmf.feature.LifeCycleListenerclasses for features X and Y namedXListenerandYListenerwith methodsactivate()anddeactivate(). A user has opened your application and the code is currently executing in feature X. The user then performs the following steps:

  1.

  Suspend the application (put it in the background).

  2.

  Start the application.

  3.

  Open feature Y.

  Which option describes the methods and the specific order in which they are invoked when the user performs these steps?

  A. AppListener.stop(), AppListener.start(), YListener.activate()

  B. XListener.deactivate(), AppListener.deactivate(), AppListener.activate(),XListener.activate(), XListener.deactivate(), YListener.activate()

  C. XListener.stop(), YListener.activate()

  D. XListener.deactivate(), XListener.activate(), XListener.deactivate(), YListener.activate()

  Correct Answer: A

• Question 35:

  You used the REST service data control wizard to build a data control from a remote REST service endpoint.

  How do you change the endpoint while you move the MAF application from testing to production?

  A. Edit theconnections.xmlfile stored in the application's.adf/Meta-Infdirectory.

  B. Edit theDataControls.dcxdata control definition file stored in the project within which the REST data control is created.

  C. Edit theadfm.xmlfile in theApplicationController/adfmsrc/Meta-INFdirectory.

  D. Edit thecacertsfile in the application's/resources/securitydirectory.

  Correct Answer: A

  After creating a web service data control, you can modify the end point of the URI. This is useful in such cases as when you migrate an application feature from a test to production environment. You modify the end point by editing the connections.xml file

• Question 36:

  Your customer currently builds native Android applications. He is intrigued by the cross- platform capabilities of Oracle MAF, but fears that distribution through the Apple App Store is complex to set up and expensive.

  Considering that your customer wants to distribute his applications to the general public and not inside his or her own organization, which three explanations can you provide about the Apple App Store to appease your customer's fears?

  A. Apple offers subscriptions to its Xcode development tools. It is possible to publish to the App Store for free with an active subscription.

  B. Apple provides the iOS provisioning profile and certificate you need to sign the application, but you do not need to use Apple's tools directly to package your MAF application since JDeveloper and OEPE will

  do the work for you if properly configured.

  C. Publishing MAF applications to the App Store is very simple because you submit them to Oracle and not to Apple.

  D. If you plan to sell your applications instead of providing them for free, you need to enroll in the iOS Developer Enterprise program.

  E. To publish to the App Store as an individual, only membership in the entry-level iOSDeveloper Program is required. Appleasks for a nominal annual membership fee. There is no need to enroll in the iOS Developer Enterprise Program.

  F. Oracle has published numerous MAF applications to the AppleAppStore without any problems and will update the MAFframework if Apple's submission requirements are changed.

  Correct Answer: BEF

• Question 37:

  In your MAF design, you have defined a "checkout" feature based on a task flow where customers place items into their shopping basket and, at the end of task flow, either purchase the items in the shopping cart or cancel the order. The items in the shopping cart are persisted in a managed bean.

  Which single bean scope is the right option for the shopping cart managed bean?

  A. applicationScope

  B. backingBeanScope

  C. pageFlowScope

  D. requestScope

  E. sessionScope

  F. viewScope

  Correct Answer: C

  Mobile Application Framework variables and managed bean references are defined within different object scopes that determine the variable's lifetime and visibility. MAF supports the following scopes, listed in order of decreasing visibility:

  Application scope--The object is available for the duration of the application (across features). Page flow scope--The object is available for the duration of a feature (single feature boundary). View scope--The object is available for the duration of the view (single page of a feature).

  Object scopes are analogous to global and local variable scopes in programming languages. The wider the scope, the higher the availability of an object. During their lifespan, these objects may expose certain interfaces, hold information, or pass variables and parameters to other objects. For example, a managed bean defined in application scope will be available for use during multiple page requests for the duration of the application. However, a managed bean defined in view scope will be available only for the duration of one page request within a feature.

• Question 38:

  Which two approaches can you use to define a managed bean in MAF?

  A. Add annotation injection in the Java class.

  B. Define it in a taskflow's XML definition file.

  C. Define it in theadfc-mobile-config.xmlfile.

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

  Correct Answer: CD

• Question 39:

  You have created a reusable feature in a feature archive (FAR) application workspace, which will be consumed and used by a master application. The FAR workspace makes use of tables in the device's SQLite database. You need the tables to be ready to accept data the first time the FAR application is started.

  Where should you code the logic to create the tables to support maximum reusability of the FAR?

  A. start()method in the master application's ApplicationController project's oracle.adfmf.application.LifeCycleListenerimplementation class

  B. activate()method in the master application's ApplicationController project's oracle.adfmf.application.LifeCycleListenerimplementation class

  C. start()method in the FAR application's ApplicationController project's oracle.adfmf.application.LifeCycleListenerimplementation class

  D. activate()methodon the FAR application's ViewController project's oracle.adfmf.feature.LifeCycleListenerimplementation class

  Correct Answer: C

• Question 40:

  Select the criterion that a developer cannot specify while selecting which CSS file to use in an MAF application.

  A. mobile operating system type

  B. mobile operating system version

  C. mobile device model

  D. logged in user ID

  E. mobile device form factor

  F. user preferences

  G. number ofAMXpages in the application

  Correct Answer: EFG
