Question 1
You are developing an application that includes a class named Customer.
The application will output the Customer class as a structured XML document by using the following code segment:
You need to ensure that the Customer class will serialize to XML.
You have the following code:
Which code segments should you include in Target 1, Target 2, Target 3 and Target 4 to complete the code? To answer, drag the appropriate code segments to the correct targets. Each code segment 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.

Question 2
You are developing an application by using C#. The application will output the text string "First Line" followed by the text string "Second Line".
You need to ensure that an empty line separates the text strings.
Which four code segments should you use in sequence? (To answer, move the appropriate code segments to the answer area and arrange them in the correct order.)

Question 3
You are testing an application. The application includes methods named CalculateInterest and LogLine. The CalculateInterest() method calculates loan interest. The LogLine() method sends diagnostic messages to a console window.
The following code implements the methods. (Line numbers are included for reference only.)
You have the following requirements:
* The CalculateInterest() method must run for all build configurations.
* The LogLine() method must run only for debug builds.
You need to ensure that the methods run correctly.
What are two possible ways to achieve this goal? (Each correct answer presents a complete solution. Choose two.)

Question 4
You are implementing a method named ProcessData that performs a long-running task. The ProcessData() method has the following method signature:
public void ProcessData(List<decimal> values, CancellationTokenSource source, CancellationToken token) If the calling code requests cancellation, the method must perform the following actions:
Cancel the long-running task.
Set the task status to TaskStatus.Canceled.
You need to ensure that the ProcessData() method performs the required actions.
Which code segment should you use in the method body?
