Question 5:

Which four options can be used to authenticate a MAF application user?

A. Facebook


C. HTTP Basic

D. Google

E. Mobile social

F. O-Auth

Correct Answer: BCEF

Mobile applications may require that user credentials be verified against a remote login server(such as the Oracle Access Manager Identity Server used by Oracle ADF Fusion web applications) or a local credential store that resides on the user\’s device. To support local and remote connectivity modes, MAF supports these authentication protocols:

HTTP Basic Mobile-Social OAuth Web SSO By default, authentication of the mobile application user is against the remote login server regardless of the authentication protocol chosen at design time. Developers may configure the application, in the case of Oracle Access Management Mobile and Social (OAMMS) and basic authentication to enable local authentication. However, initially, because the local credential store is not populated with credentials, login to access secured application features requires authentication against a remote login server. Successful remote authentication enables the subsequent use of the local credential store, which houses the user\’s login credentials from the authentication server on the device. Thus, after the user is authenticated against the server within the same application session (that is, within the lifecycle of the application execution), MAF stores this authentication context locally, allowing it to be used for subsequent authentication attempts. In this case, MAF does not contact the server if the local authentication context is sufficient to authenticate the user. Although a connection to the authentication server is required for the initial authentication, continual access to this server is not required for applications using local authentication.

Question 6:

A service developer is creating a service that will be used by mobile clients. Which piece of advice should the developer consider while designing it?

A. Design for next generation interfaces to ensure that their services will not need to change in the future.

B. Carefully choose the implementation language and the monitoring capabilities.

C. Consider the interface types, payloads types, and security approaches which are easily consumed by mobile devices.

D. Create services that are arcane in nature to enhance the security of the services.

Correct Answer: C

Question 7:

When developing a MAF application for service technicians, you determine that the mobile technician will need to extensively describe the condition of the item he or she is servicing, including the area that is broken and any other pertinent details.

How would you implement this in an MAF application to avoid excessive typing?

A. Use a remote URL page to enable the technician to specify the description in a browser- based page.

B. Use the camera integration feature to allow the technician to take a photo of the serviced item.

C. Use an input text area to allow for multiple lines of text.

D. Use the voice recognition integration feature to allow the technician to enter details by voice.

Correct Answer: D

Question 8:

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. Stop the user from invoking the phone device service, which relies on a 2G, 3G, or 4G connection if the network status returnswifi.

D. Call an external web service to refresh data if a connection is available; otherwise, use a local cached copy of the data.

Correct Answer: B

Question 9:

For a MAF application to register anURL scheme to be invoked by other applications on the device, it must define two things. First, it defines the URL scheme in themaf- application.xmlfile.

What is the second thing the application must do to be invoked and handle the event when the application is initiated by the URL scheme?

A. In themaf-application.xmlfile, define an event listener with an associated Java class to respond.

B. Within the application\’s LifeCycleListenerImpl.start() method, register an EventListener to fire and respond to the event.

C. Include an URL scheme Cordova plugin to respond to the event on each platform.

D. In themaf-application.xmlfile, configure the `Push-Notification\’ device access privilege.

Correct Answer: B

Question 10:

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. Thelogging.propertiesfile 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.PatternFormatt er 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?

Correct Answer: CE

Question 13:

Which three statements are true about MAF data controls?

A. A data control is an adapter that exposes a simpler, unified development API for MAF application developers to declaratively and programmatically access data services.

B. Data controls expose data service structures in the data controls panel. The information exposed includes attributes, collections, and public methods.

C. Data controls in MAF exist for remote SOAP and REST services only and handle all of the XML to Java object marshalling and unmarshalling.

D. Data controls are configured in one or moreDataControls.dcxfiles.

E. MAF is restricted to ten data controls per mobile application.

Correct Answer: BCD

Question 14:

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 15:

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.
