Given the following code:

What will the alert(WL.Client.getUserPref('key1')); show?

A. The alert will not show since WL.Client.setUserPref cannot be called in the for loop since it is an asynchronous function.

B. updatedValue1 since WL.Client.setUserPref({'key1' : 'updatedValue1'}); will replace the value of key1 set in the for loop.

C. value1, updatedValue1 or null since WL.Client.setUserPref is an asynchronous function and there is no guarantee which call, if any,will return first.

D. value1 since WL.Client.setUserPref('key1', 'updatedValue1'); will fail because WL.Client.deleteUserPref ('key1') was notcalled before setting the new value.

A developer is invoking WL.Client.invokeProcedure(invocationData, options), using the options object and callback functions that are shown below.

Which two statements describe the outcome of this scenario? (Choose two.)

A. The invocationContext will be returned to the success and failure handlers.

B. The function failure will be invoked on client-side errors, however, not invoked on server- side errors.

C. The data returned by the invoked procedure is saved on response.invocationResult in the case of a successful call.

D. The data returned by the invoked procedure is saved on response.invocationContext in the case of a successful call.

E. The data returned by the invoked procedure is saved on response.invocationResult in the case of an unsuccessful call.

A Worklight mobile application named test has the following code:

What is the cause of this behavior?

A. The server is unreachable.

B. The heartBeatIntervalInSecs is set to a value that is too low.

C. The heartBeatIntervalInSecs is set to a value that is too high.

D. The serverSessionTimeout value needs to be set to a value lower than heartBeatIntervalInSecs.

A developer previewing a Worklight application for an Android device in the Mobile Browser Simulator now wants to preview the application for an iOS device. Is it possible to preview the application for both devices on a same page of the Mobile Browser Simulator?

A. No because the developer can view only one device at a time.

B. Yes by clicking the Add Device button to select another device.

C. Yes by enabling the User Agent switching to select another device.

D. Yes by adding another device in the Device section of the Cordova API plugin.

Which of the following is not a Worklight project folder?

A. adapters
