IBM Worklight V6.0 Mobile Application Development Sample Questions:

1. A mobile application developer is using a Worklight adapter to retrieve an XML data feed from a remote system. The data obtained from the remote system contains much more data than is needed by the mobile application. What specific Worklight capability should the application developer use to reduce the data being returned from the Worklight adapter?

A) Utilize a Java JSON library and call Java code from the the Worklight adapter that converts the returned XML data into a JSON object to bereturned from the adapter.
B) Ensure that the XML feed only has the desired information returned.
C) When calling the invoke command that retrieves the remote feed, specify a transformation that uses XSLT to parse the returned data.
D) When the data is returned to the mobile application from the Worklight adapter, use for-loops and string comparison to extract the desireddata.

2. A mobile application developer created a Mobile Web app and optimized it using the Minification feature in Worklight Studio. The developer needs to debug the application JavaScript in a comfortable manner. Consider the following application structure.

Which includes/excludes rules configuration should the application developer use in the minification process to debug only the application's JavaScript after the application's web
resources have been minified? (choose 2)

A) includes="**/common/*.css"
B) excludes="**/jqueryMobile/*.js"excludes="**/jqueryMobile/*.js"
C) excludes="**/js/exampleApp.js"excludes="**/js/exampleApp.js"
D) includes="**/*.js; *.css"
E) excludes="**.js; *.css"excludes="**.js; *.css"

3. A mobile application developer has created a Hybrid application for Android phones and tablets using skins to have a different interface on the phones and the tablets. The application developer updates one of the HTML resources which is targeted for tablets, increments the version number from 1.0 to 2.0 and deploys it to the server. Which correctly describes the scenario when an Android phone tries to access the application? The application:

A) gets a direct update prompt and but does not get updated with the resource.
B) gets a direct update prompt, gets updated with the changed resource and its version is 2.0.
C) does not receive the direct update.
D) gets a direct update prompt, gets updated with the changed resource and its version is 1.0.

4. A mobile application developer discovers that the internal application server will not start due to a port conflict. What should the application developer do to resolve this conflict?

A) Locate and remove the wlp/user/servers/worklightServer/server.xml file and then restart the server so that it will create a newconfiguration on startup.
B) Modify the server.xml file, changing the port value to an unused port number.
C) Modify the conf/tomcat-users.xml file changing the port value to an unused port number.
D) Install a new instance of the Worklight Studio so that the installation detects the existing server.

5. A mobile application developer needs to deploy a mobile application developed using IBM Worklight Studio to a remote server. To do so, which mandatory file must be present on the remote server?

A) worklight-extension-api.jar
B) worklight-jee-library.jar
C) derby.jar
D) com.ibm.ws.wim.core.jar
