You have the following requirements:
. The GetData() method must return a string value that contains the entire response from the web service. . The application must remain responsive while the GetData() method runs.
You need to implement the GetData() method.
How should you complete the relevant code? (To answer, drag the appropriate objects to the correct locations in the answer area. Each object may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.)

Q3. - (Topic 1)
You use the Task.Run() method to launch a long-running data processing operation. The data processing operation often fails in times of heavy network congestion.
If the data processing operation fails, a second operation must clean up any results of the first operation.
You need to ensure that the second operation is invoked only if the data processing operation throws an unhandled exception.
What should you do?
A. Create a TaskCompletionSource<T> object and call the TrySetException() method of the object.
B. Create a task by calling the Task.ContinueWith() method.
C. Examine the Task.Status property immediately after the call to the Task.Run() method.
D. Create a task inside the existing Task.Run() method by using the AttachedToParent option.
Answer: B
Q4. - (Topic 1)
You are debugging an application that calculates loan interest. The application includes the following code. (Line numbers are included for reference only.)
You have the following requirements:
. The debugger must break execution within the Calculatelnterest() method when the loanAmount variable is less than or equal to zero. . The release version of the code must not be impacted by any changes.
You need to meet the requirements.
What should you do?
A. Insert the following code segment at tine 05: Debug.Write(loanAmount > 0);
B. Insert the following code segment at line 05: Trace.Write(loanAmount > 0);
C. Insert the following code segment at line 03: Debug.Assert(loanAmount > 0);
D. Insert the following code segment at line 03: Trace.Assert(loanAmount > 0);
Answer: C
Explanation:
By default, the Debug.Assert method works only in debug builds. Use the Trace.Assert method if you want to do assertions in release builds. For more information, see Assertions in Managed Code. http://msdn.microsoft.com/en-us/library/kssw4w7z.aspx
