You have the following code:

You need to retrieve all of the numbers from the items variable that are greater than 80.
Which code should you use?

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 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 implementing a new method named ProcessDat
a 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 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 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.)

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 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.)

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 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?
