• Question 72:

  You are developing an application by using C#. The application will write events to an event log. You plan to deploy the application to a server.

  You create an event source named MySource and a custom log named MyLog on the server.

  You need to write events to the custom log.

  Which code segment should you use?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  D. Option D

• Question 73:

  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:

  1.

  Log all exceptions by using the LogException() method of the ExceptionLogger class.

  2.

  Rethrow the original exception, including the entire exception stack.

  You need to meet the requirements.

  Which code segment should you use?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  A. Option A

  Once an exception is thrown, part of the information it carries is the stack trace. The stack trace is a list of the method call hierarchy that starts with the method that throws the exception and ends with the method that catches the exception. If an exception is re-thrown by specifying the exception in the throw statement, the stack trace is restarted at the current method and the list of method calls between the original method that threw the exception and the current method is lost. To keep the original stack trace information with the exception, use the throw statement without specifying the exception.

• Question 75:

  DRAG DROP

  You are creating a method that saves information to a database.

  You have a static class named LogHelper. LogHelper has a method named Log to log the exception.

  You need to use the LogHelper Log method to log the exception raised by the database server. The solution must ensure that the exception can be caught by the calling method, while preserving the original stack trace.

  How should you write the catch block? (Develop the solution by selecting and ordering the required code snippets. You may not need all of the code snippets.)

• Question 78:

  You have a C# application named App1 that invokes a method in an external assembly named Assembly1. Assembly1 is written in C++ and is natively compile by using a debug build.

  When you debug App1, you do not see any debug information for Assembly1.

  You need to ensure that when you debug App1, you see the debug information for Assebly1.

  What should you do?

  A. On the Debugging page of the configuration properties for the C++ project, set the Debugger Type to Native Only.
  B. On the Debugging page of the configuration properties for the C++ project, set the Debugger Type to Mixed.
  C. On the Debug page of the project properties for App1, click Enable native code debugging.
  D. In the project properties for App1, set the working directory to the same directory as Assembly1.
  B. On the Debugging page of the configuration properties for the C++ project, set the Debugger Type to Mixed.

• Question 79:

  You are developing an application that contains a class named TheaterCustomer and a method named ProcessTheaterCustomer. The ProcessTheaterCustomer() method accepts a TheaterCustomer object as the input parameter.

  You have the following requirements:

  Store the TheaterCustomer objects in a collection. Ensure that the ProcessTheaterCustomer() method processes the TheaterCustomer objects in the order in which they are placed into the collection.

  You need to meet the requirements.

  What should you do?

  A. Create a System.Collections.Stack collection. Use the Push() method to add TheaterCustomer objects to the collection, Use the Peek() method to pass the objects to the ProcessTheaterCustomer() method.
  B. Create a System.Collections.Queue collection. Use the Enqueue() method to add TheaterCustomer objects to the collection. Use the Dequeue() method to pass the objects to the ProcessTheaterCustomer() method.
  C. Create a System.Collections.SortedList collection. Use the Add() method to add TheaterCustomer objects to the collection. Use the Remove() method to pass the objects to the ProcessTheaterCustomer() method.
  D. Create a System.Collections.ArrayList collection. Use the Insert() method to add TheaterCustomer objects to the collection. Use the Remove() method to pass the objects to the ProcessTheaterCustomer() method.
  B. Create a System.Collections.Queue collection. Use the Enqueue() method to add TheaterCustomer objects to the collection. Use the Dequeue() method to pass the objects to the ProcessTheaterCustomer() method.
