Demo Questions

Question 1
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?
  1. Apple offers subscriptions to its Xcode development tools. It is possible to publish to the App Store for free with an active subscription.
  2. 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.
  3. Publishing MAF applications to the App Store is very simple because you submit them to Oracle and not to Apple.
  4. If you plan to sell your applications instead of providing them for free, you need to enroll in the iOS Developer Enterprise program.
  5. To publish to the App Store as an individual, only membership in the entry-level iOS Developer Program is required. Apple asks for a nominal annual membership fee. There is no need to enroll in the iOS Developer Enterprise Program.
  6. Oracle has published numerous MAF applications to the Apple AppStore without any problems and will update the MAF framework if Apple’s submission requirements are changed.
Correct answer: BEF
Question 2
Which two statements about using HTTPS to secure access to a mobile service are true?
  1. HTTPS is impervious to attacks.
  2. HTTPS secures only the transport to the service.
  3. HTTPS can be used for data redaction.
  4. HTTPS alone is insufficient for services that require user-level authentication.
Correct answer: BD
Question 3
Which three statements are true about MAF data controls?
  1. A data control is an adapter that exposes a simpler, unified development API for MAF application developers to declaratively and programmatically access data services.
  2. Data controls expose data service structures in the data controls panel. The information exposed includes attributes, collections, and public methods.
  3. Data controls in MAF exist for remote SOAP and REST services only and handle all of the XML to Java object marshalling and unmarshalling.
  4. Data controls are configured in one or more DataControls.dcx files.
  5. MAF is restricted to ten data controls per mobile application.
Correct answer: BCD
Question 4
After importing a Feature Archive into an application, what else must you do to include its features into your application?
  1. Create a new deployment profile.
  2. Add a login URL.
  3. Add a task flow.
  4. Add one or more feature references.
Correct answer: D
Explanation:
Question 5
Which two approaches are encompassed by service mediation?
  1. loosely coupling service consumers with enterprise systems
  2. the ability to provide additional information by aggregating data from multiple enterprise systems
  3. rapid prototyping of service interfaces
  4. rapid deployment of services into the cloud
Correct answer: BC
Question 6
You and your colleague develop different parts of the same MAF application. He recently joined the company and needs to set up his workstation and devices for debugging. The application needs to be tested on Apple iPads and various Android-powered tablets. Your colleague has been assigned an Apple MacBook Pro as his workstation. 
Which three tasks must you perform to ensure that your colleague will be able to debug the application on iOS and Android devices?
  1. Make sure that the network device access option is enabled in the maf-application.xml file.
  2. Obtain a debug signing certificate from the Google Play store developer support.
  3. Check that the settings in the Mobile Run configuration match those found in the cvm.properties file.
  4. Register any Apple device involved in testing and debugging under the appropriate Apple Developer account.
  5. Disable USB debugging on all the Android devices involved because this will interfere the IDE’s debugger.
  6. Establish a Bluetooth link between your colleague’s workstation and the devices.
Correct answer: ACD
Explanation:
Question 7
You are building a new MAF application and the design documentation specifies the following requirements about the application logs:
  1. Log entries by the MAF framework must be kept at a minimum. 
  2. Log entries generated by your own business logic must be as detailed as possible for compliance purpose. 
The logging.properties file for your application currently looks like this:
.handlers=com.sun.util.logging.ConsoleHandler 
.formatter=com.sun.util.logging.SimpleFormatter 
oracle.adfmf.util.logging.ConsoleHandler.level=SEVERE 
oracle.adfmf.util.logging.ConsoleHandler.formatter=oracle.adfmf.util.logging.PatternFormatter 
oracle.adfmf.util.logging.PatternFormatter.pattern=[%LEVEL% - %LOGGER% - %CLASS% - %METHOD%]%MESSAGE% 
oracle.adfmf.application.useParentHandlers=false 
oracle.adfmf.application.handlers=oracle.adfmf.util.logging.ConsoleHandler 
oracle.adfmf.application.level=INFO 
oracle.adfmf.framework.useParentHandlers=false 
oracle.adfmf.framework.handlers=oracle.adfmf.util.logging.ConsoleHandler 
oracle.adfmf.framework.level=FINE 
Which two actions would you perform to fulfill the requirements?
  1. Use loggers from the com.sun.logging package in you code.
  2. Set oracle.adfmf.application.level to FULL in the logging.properties file.
  3. Set .handlerstooracle.adfmf.util.logging.handlers.SQLiteHandler in the logging.properties file to store the logs in a database since this is required by regulations.
  4. Set oracle.adfmf.application.level to FINEST in the logging.properties file.
  5. Set oracle.adfmf.framework.level to SEVERE in the logging.properties file.
Correct answer: CD
Question 8
Which use case describes why you should use the JSONBeanSerializationHelper class in MAF?
  1. Use it as a Java interface to data objects so that they can be serialized to server-side REST services.
  2. Use it to parse JSON results to Java data objects and collections.
  3. Use it to validate JSON result strings for matching a specific data schema.
  4. Use it as an adapter class to access the REST-JSON data control from JAVA (for example, from managed beans).
Correct answer: B
Explanation:
Question 9
Which two limitations apply to the REST web services data control?
  1. REST web service data controls can be used only with REST services that do not require authentication.
  2. REST web service data controls support only XML payloads.
  3. REST web service data controls support only UTF-8 character encoding.
  4. The REST web service data control wizard does not perform changes on existing REST data controls. If the requirement is to change an existing data control configuration, then the existing data control must be deleted before running the REST service data control.
Correct answer: CD
Explanation:
The REST web service adapter only supports UTF-8 character set on mobile applications. UTF-8 is embedded in the adapter program. 
The REST web service adapter only supports UTF-8 character set on mobile applications. UTF-8 is embedded in the adapter program. 
Question 10
Which two capabilities determine your decision to select either a native or a hybrid architecture over a web mobile architecture?
