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.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

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 3 and the loanAmount value is 9750, the loanRate must be set to 8.25 percent.
You need to adjust the loanRate value to meet the requirements.
What should you do?

You are creating a console application named Appl.
App1 retrieves data from the Internet by using JavaScript Object Notation (JSON).
You are developing the following code segment (line numbers are included for reference only):

You need to ensure that the code validates the JSON string. Which code should you insert at line 03?

You have the following code (line numbers are included for reference only):

You need to ensure that if an exception occurs, the exception will be logged.
Which code should you insert at line 28?

You are creating a console application named App1.
App1 will validate user input for order entries.
You are developing the following code segment (line numbers are included for reference only):

You need to complete the code segment. The solution must ensure that prices are positive and have two
decimal places. Which code should you insert at line 03?
