1z1-441 Exam Training Practice Tests (Oracle Mobile Development 2015 Essentials)]

Question 1

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. Call an external web service to refresh data if a connection is available; otherwise, use a local cached copy of the data. D. Stop the user from invoking the phone device service, which relies on a 2G, 3G, or 4G connection if the network status returnswifi.

Correct Answer: B

Question 2

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?

A. Use loggers from thecom.sun.loggingpackage in you code. B. Set.handlerstooracle.adfmf.util.logging.handlers.SQLiteHandlerin thelogging.propertiesfile to store the logs in a database since this is required by regulations. C. Setoracle.adfmf.application.leveltoFULLin thelogging.propertiesfile. D. Setoracle.adfmf.framework.leveltoSEVEREin thelogging.propertiesfile. E. Setoracle.adfmf.application.leveltoFINESTin thelogging.propertiesfile.

Correct Answer: B,E

Question 3

Select three common functionalities that are enabled when a MAF application is secured with Mobile Application Management (MAM) solutions such as Oracle Mobile Security Suite.

A. Display the user ID and password in a log file for debugging purposes. B. Encrypt the local database and files on the device. C. Discover and download mobile applications from an enterprise app store. D. Hide UI fields that contain data not authorized by the logged-in user. E. Enforce a data leak protection policy such as disabling copy-paste in the application.

Correct Answer: B,C,E

Question 4

Identify two use cases that require Java access to a SOAP data control.

A. exposing SOAP header information for edit B. mapping a SAOP payload to a custom data object structure on the client side. C. adding web service security D. client-side caching of data queried from a SOAP service

Correct Answer: B,D

Question 5

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

A. Use the REST service adapter to query data from SQLite in JSON format. B. Configure the SQLite database data control and use the data controls panel to drag and drop data collections and attributes onto the AMX view. C. Create a TopLink persistence layer to query and update the database. The AMX user interface components bind to the EJB session facade. D. Use a JavaBean to wrap calls to SQLite database and create a JavaBean DataControlfrom it, that then appears in the data controls panel.

Question 6

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

A. SOAP 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. B. The SOAP web service returns an XML response, whereas the REST service (as per thequestion) returns a JSON response. The two cannot be combined in a unified data control exposure. C. REST 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. D. Data 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.

Question 7

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

A. mobile device form factor B. mobile operating system version C. mobile device model D. logged in user ID E. mobile operating system type F. number ofAMXpages in the application G. user preferences

Correct Answer: A,F,G

Question 8

In an AMX page, you want to hide/show a button based on the mobile device having a camera.
Which is a valid EL expression to test for the camera?

A. <amx:commandButton rendered="#{deviceScope.device.hasCamera}"/> B. <amx:commandButton rendered="#{device.camera}"/> C. <amx:commandButton rendered="#{device.hasCamera}"/> D. <amx:commandButton rendered="#{deviceScope.camera}"/>

Correct Answer: D

Question 9

If your MAF application uses a SOAP web service data control with the oracle/wss_username_token_over_ssl_client_policy security policy applied, where will the user credentials (user ID and password) be injected at run time?

A. in theUserCredentialsattribute of the SOAP envelope B. in the WS-SecurityUsernameTokenheader C. in the HTTP Basic authentication header D. in a cookie, if the remote server supports them
