You are developing an application that will write data to a file. The application includes the following code segment. (Line numbers are included for reference only.)
* Missing code *
You need to ensure that the WriteData() method will write data to a file.
Which four code segments should you insert in sequence at line 03? (To answer, move the appropriate code segments from the list of code segments to the answer area and arrange them in the correct order.)

You are implementing a new method named ProcessData. The ProcessData() method calls a third-party component that performs a long-running operation to retrieve stock information from a web service.
The third-party component uses the IAsyncResult pattern to signal completion of the long-running operation so that the UI can be updated with the new values.
You need to ensure that the calling code handles the long-running operation as a System.Threading.Tasks.Task object to avoid blocking the UI thread.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

You are creating a class library that will be used in a web application.
You need to ensure that the class library assembly is strongly named.
What should you do?

You are developing an application that uses structured exception handling. The application includes a class named ExceptionLogger.
The ExceptionLogger class implements a method named LogException by using the following code segment:
public static void LogException(Exception ex)
You have the following requirements:
* Log all exceptions by using the LogException() method of the ExceptionLogger class.
* Rethrow the original exception, including the entire exception stack.
You need to meet the requirements.
Which code segment should you use?

You are developing an application that uses multiple asynchronous tasks to optimize performance.
You need to retrieve the result of an asynchronous task.
Which code segment should you use?

You are creating a console application by using C#.
You need to access the application assembly.
Which code segment should you use?

You have the following code:

You need to display all of the vehicles that start with the letter "A".
How should you complete the code? To answer, drag the appropriate code elements to the correct targets. Each code element 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.
NOTE: Each correct selection is worth one point.

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.)

You are developing an application that implements a set of custom exception types. You declare the custom exception types by using the following code segments:

The application includes a function named DoWork that throws .NET Framework exceptions and custom exceptions. The application contains only the following logging methods:

The application must meet the following requirements:
When ContosoValidationException exceptions are caught, log the information by using the static void Log(ContosoValidationException ex) method.
When ContosoDbException or other ContosoException exceptions are caught, log the information by using the static void Log(ContosoException ex) method.
When generic exceptions are caught, log the information by using the static void Log(Exception ex) method.
You need to meet the requirements.
You have the following code:

Which code segments should you include in Target 1, Target 2 and Target 3 to complete the code? (To answer, drag the appropriate code segments to the correct targets in the answer area. 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.)

You are developing an application. The application includes classes named Employee and Person and an interface named IPerson.
The Employee class must meet the following requirements:
* It must either inherit from the Person class or implement the IPerson interface.
* It must be inheritable by other classes in the application.
You need to ensure that the Employee class meets the requirements.
Which two code segments can you use to achieve this goal? (Each correct answer presents a complete solution. Choose two.)

You are developing an application that includes a class named UserTracker. The application includes the following code segment. (Line numbers are included for reference only.)

You need to add a user to the UserTracker instance.
What should you do?
