Correct Answer: ADE /Reference: QUESTION 19 Which four options can be used to authenticate a MAF application user? A. Facebook B. SSO C. HTTP Basic D. Google E. Mobile social

11 F. O-Auth Correct Answer: BCEF /Reference: : 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 20 Identify three features of Oracle Mobile Security Suite. A. It creates a separate container for corporate applications on a mobile device. B. It modifies service endpoints to allow for changing authentication protocols. C. It wipes data from a lost or stolen device. D. It allows single sign-on among different applications. E. It integrates heterogeneous services across a network. Correct Answer: BCD /Reference: : Reference:

The requirement is to show a multipage wizard for an MAF application functionality when the application runs on a smartphone and a single page layout for the same functionality when the application runs on a tablet. Which two options allow you to implement this use case? A. A Feature can have multiple contents (AMX pages, AMX Task Flow, and so on). A content constraint can be defined on the first content to hide when the application runs on a smartphone and to show when it runs on a tablet. This way, the first content configured for a Feature holds the single page layout, whereas the second (with no constraints defined) has the multipage wizard function. B. A Feature LifecycleListener class can be created and configured to load AMX content upon application start. In this case, Java, using the AdfmfContainerUtilities framework helper class, determines the type of device to be smartphone tablet and switches the content. C. Two MAF Features can be created, one for the single page view and the other for the multipage wizard. Constraints defined on the feature configuration conditionally switch between the two options. D. Selecting the Enable Adaptive Design check box in the maf-application.xml file visual editor allows you to configure constraints on the application level that, upon application start, tell the framework which MAF Features to load when the application is started on a smartphone and which Features to load when the application is started on a tablet.
