You are developing an application that includes a method named SendMessage.
You need to ensure that the SendMessage() method is called with the required parameters.
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.
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?

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 developing an application that includes a class named Employee and a generic list of employees. The
following code segment declares the list of employees:
List<Employee> employeesList = new List<Employee>();
You populate the employeesList object with several hundred Employee objects.
The application must display the data for five Employee objects at a time.
You need to create a method that will return the correct number of Employee objects.
Which code segment should you use?

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?

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

You need to ensure that code generated by the GenerateCode() method represents a class that can be
accessed by all objects in its application domain.
Which two code segments can you insert at line 05 to achieve this goal? (Each correct answer presents a
complete solution. Choose two.)

An application contains code that measures reaction times. The code runs the timer on a thread separate from
the user interface. The application includes the following code. (Line numbers are included for reference only.)

You need to ensure that the application cancels the timer when the user presses the Enter key.
Which code segment should you insert at line 14?

You are modifying an application that processes loans. The following code defines the Loan class. (Line
numbers are included for reference only.)

Loans are restricted to a maximum term of 10 years. The application must send a notification message if a loan
request exceeds 10 years.
You need to implement the notification mechanism.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

You are developing an application for a bank. The application includes a method named ProcessLoan that
processes loan applications. The ProcessLoan() method uses a method named CalculateInterest. The
application includes the following code:
You need to declare a delegate to support the ProcessLoan() method.
Which code segment should you use?

You are implementing a new method named ProcessData. The ProcessData() method calls a third-party
component that performs a long-running operation.
The third-party component uses the IAsyncResult pattern to signal completion of the long-running operation.
You need to ensure that the calling code handles the long-running operation as a
System.Threading.Tasks.Task object.
