You are debugging an application that calculates loan interest. The application includes the following code. (Line numbers are included for reference only.)

You need to ensure that the debugger breaks execution within the CalculateInterest() method when the loanAmount variable is less than or equal to zero in all builds of the application.
What should you do?

• A.Insert the following code segment at line 03:
  Debug.Assert(loanAmount > 0);
• B.Insert the following code segment at line 05:
  Debug.Write(loanAmount > 0);
• C.Insert the following code segment at line 05:
  Trace.Write(loanAmount > 0);
• D.Insert the following code segment at line 03:
  Trace.Assert(loanAmount > 0);

You are creating an application that manages information about your company's products. The application includes a class named Product and a method named Save.
The Save() method must be strongly typed. It must allow only types inherited from the Product class that use a constructor that accepts no parameters.
You need to implement the Save() method. Which code segment should you use?

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

You are developing an application.
The application contains the following code:

When you compile the code, you receive the following syntax error message: "A previous catch clause already catches all exceptions of this or a super type ('System.Exception')." You need to ensure that the code can be compiled. What should you do?

• A.Catch the ArgumentException exception instead of the ArgumentNullException exception.
• B.Throw a new exception in the second catch block.
• C.Catch the ArgumentNullException exception first.
• D.Re-throw the exception caught by the second catch block.

You are implementing a method named ProcessReports that performs a long-running task. The ProcessReports() method has the following method signature:
public void ProcessReports(List<decimal> values,CancellationTokenSource cts, CancellationToken ct) 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 ProcessReports() method performs the required actions.
Which code segment should you use in the method body?

• A.cts.Cancel();
• B.throw new AggregateException();
• C.ct.ThrowIfCancellationRequested() ;
• D.if (ct.IsCancellationRequested)
  return;

You are developing an application that will process personnel records.
The application must encrypt highly sensitive data.
You need to ensure that the application uses the strongest available encryption.
Which class should you use?

• A.System.Security.Cryptography.DES
• B.System.Security.Cryptography.RC2
• C.System.Security.Cryptography.Aes
• D.System.Security.Cryptography.TripleDES
