Question No. 2

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

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?

AIn themaf-application.xml file, define an event listener with an associated Java class to respond.

BWithin the application's LifeCycleListenerImpl.start() method, register an EventListener to fire and respond to the event.

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

DIn themaf-application.xmlfile, configure the 'Push-Notification' device access privilege.

Question No. 3

Which three are correct practices by developers who are creating a MAF application?

Ausing CSS files to override out-of-the-box styles rather than specifying custom styles in the inline style property of the individual UI component

Bavoiding using large images in the application

Cloading all of the application data from the server in one call to avoid having to call the same service to retrieve data again

Dcaching data in the local database when network reliability is suspect

Eexposing server data through SOAP services rather than using REST because WSDL provides better payload documentation

Correct Answer: A, B, D

Question No. 4

Which statement is true about consolidating data queried from a SOAP web service and a REST-JSON web service locally on the MAF client so that it can be exposed in a single data control?

AThe SOAP web service returns an XML response, whereas the REST service (as per the question) returns a JSON response. The two cannot be combined in a unified data control exposure.

BSOAP web services and REST web services with a JSON response (as per the question) can each be transformed in data objects stored in data services. A Java layer on top can be used to expose the information on a single data control interface.

CData queried from different web service sources and web service types must be transformed and consolidated on the remote server to ensure unique keys and payloads.

DREST web services with a JSON payload (as per the question) can be accessed from the SOAP data control. The framework automatically converts the JSON string schema to an XML structure.

Question No. 5

Which two methods allow you to update a MAF application without reinstalling the application?

AUse the standard customization mechanism provided by JDeveloper and Oracle Metadata Service (MDS) to customize AMX application feature artifacts and metadata files.

BUse the Configuration Service to configure the end points used by the web services and login connections accessed by the MAF application.

CConfigure the MAF application to accept push notifications sent over the Apple Push Notification Service (APNs) and Google Cloud Messaging (GCM) by the Configuration Service.

DCreate a new MAF application from an existing one by first packaging the original MAF application as a Mobile Application Archive (.maa) file and then, by deriving a new mobile application from this file.

ERetrieve an URL from the end user through the user interface and call AdfmfJavaUtilities.overrideConnectionProperty to update the end point for a connection.
