Question #19

A mobile application developer has supplied a publicSigningKey in the application-descriptor.xml file to enable Application Authenticity for an Android application. After the developer installed the application on an Android device, the publicSigningKey was altered during a subsequent build in Worklight Studio Consumer Edition. What effect will this have on the deployed application?

A. The Application Authenticity check will fail due to mismatch in the response from the client to the challenge sent by the Worklight Server.

B. Since the application has already been installed, it will continue to function with its existing key.

C. The Application Authenticity is set to Disabled by default, so despite a mismatch in the response from the client to the challenge sent by theWorklight Server, the application will continue to function.

D. The Android environment uses both a bundleId and a publicSigningKey, so in this case the application on Android will not go through theApplication Authenticity check.

Question #21

A mobile application developer needs to create an application for a hospital that will only allow a doctor access to medical records while inside the hospital. How can the mobile application developer accomplish this task using Worklight APIs?

A. On the device, use WL.Client.isInsidePolygon() to determine if the doctor is in the hospital, then use WL.Server.setUserRealm() toallow or restrict access.

B. On the device, use a PositionChange trigger to signal when the user moves into a different area, then use WL.Server.setUserRealm() toto allow or restrict access.

C. Within an adapter, add event listeners WL.Events.GEOFENCE_ENTER and WL.Events.GEOFENCE_EXIT so a callback sets a variable whenevera doctor moves in or out of the geofence. Check the variable when the adapter is called to determine if the doctor is in an authorized location. Ifnot, do not process further.

D. Within an adapter, use WL.Server.getClientDeviceContext() to determine if the doctor is in an authorized location. If not, do not processfurther.

Question #23

A mobile application developer has been asked to write an application that will work even when there is no connectivity. When input data is to be saved, the application must determine whether it should be written to the server or to a cache. How should the application developer do this?

A. Use the Worklight API call WL.Server.setConnectivity() to register a function to be called whenever the application goes offline or comesback online.

B. Use the Worklight API call WL.Framework.addEventListener to register callbacks when WL.Events.WORKLIGHT_IS_CONNECTED andWL.Events.WORKLIGHT_IS_DISCONNECTED are fired by the Worklight framework.

C. Call WL.Server.isConnected() before every call to the Worklight server, and write to the cache if it returns false.

D. Use the JavaScript API call Document.addEventListener to register callbacks when WL.Events.WORKLIGHT_IS_CONNECTED andWL.Events.WORKLIGHT_IS_DISCONNECTED are fired by the Worklight framework.

Question #24

A mobile application developer has created a Worklight adapter, largeData, which returns a large amount of data. Due to network latency, the application developer would like to compress the data returned. How can the application developer compress the data sent between the mobile device and the Worklight server? The developer can set compressResponse to true in the:

A. largeData.xml file.

B. invokeProcedure function.

C. largeData-impl.js file.

D. application-descriptor.xml file.
