• Question 41:

  DRAG DROP

  You have a class named Customer and a class named Order.

  The customer class has a property named Orders that contains a list of Order objects.

  The Order class has a property named OrderDate that contains the date of the Order.

  You need to create a LINQ query that returns all of the customers who had at least one order during the year 2005.

  You write the following code.

  

  How should you complete the code? To answer, drag the appropriate code elements to the correct targets in the answer area. 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.

• Question 42:

  You are creating a class named Loan.

  The Loan class must meet the following requirements:

  Include a member that represents the rate for a Loan instance. Allow external code to assign a value to the rate member. Restrict the range of values that can be assigned to the rate member.

  You need to implement the rate member to meet the requirements.

  In which form should you implement the rate member?

  A. public static property
  B. public property
  C. public static field
  D. protected field
  B. public property

  For a public the type or member can be accessed by any other code in the same assembly or another assembly that references it.

• Question 43:

  You need to write a console application that meets the following requirements:

  If the application is compiled in Debug mode, the console output must display Entering debug mode.

  If the application is compiled in Release mode, the console output must display Entering release mode.

  Which code should you use?

  

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

  When the C# compiler encounters an #if directive, followed eventually by an #endif directive, it will compile the code between the directives only if the specified symbol is defined. Unlike C and C++, you cannot assign a numeric value to a symbol; the #if statement in C# is Boolean and only tests whether the symbol has been defined or not. For example, #define DEBUG // ... #if DEBUG Console.WriteLine("Debug version"); #endif

• Question 44:

  DRAG DROP

  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.

  How should you complete the relevant code? (To answer, drag the appropriate code segments to the correct locations 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.)

• Question 45:

  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?

  

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

  Use the async modifier to specify that a method, lambda expression, or anonymous method is asynchronous. If you use this modifier on a method or expression, it's referred to as an async method.

  Example:

  public async Task ExampleMethodAsync()

  {

  // . . . .

  }

• Question 46:

  You are evaluating a method that calculates loan interest. The application includes the following code segment. (Line numbers are included for reference only.)

  

  When the loanTerm value is 5 and the loanAmount value is 4500, the loanRate must be set to 6.5 percent.

  You need to adjust the loanRate value to meet the requirements.

  What should you do?

  A. Replace line 15 with the following code segment: loanRate = 0.065m;
  B. Replace line 07 with the following code segment: loanRate = 0.065m;
  C. Replace line 17 with the following code segment: interestAmount = loanAmount * 0.065m * loanTerm;
  D. Replace line 04 with the following code segment: decimal loanRate = 0.065m;
  A. Replace line 15 with the following code segment: loanRate = 0.065m;

  ---

  Line 15 will be executed when the loanTerm value is 5.

• Question 47:

  You are developing an application that uses a .config file.

  The relevant portion of the .config file is shown as follows:

  

  You need to ensure that diagnostic data for the application writes to the event log by using the configuration specified in the .config file. What should you include in the application code?
