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?

You are creating an application that reads from a database.
You need to use different databases during the development phase and the testing phase by using conditional
compilation techniques.
What should you do?

DRAG DROP
You are developing an application that will write data to a file. The application includes the following code
segment. (Line numbers are included for reference only.)
You need to ensure that the WriteData() method will write data to a file.
Which four code segments should you insert in sequence at line 03? (To answer, move the appropriate code
segments from the list of code segments to the answer area and arrange them in the correct order.)
Select and Place:

You need to create a method that can be called by using a varying number of parameters.
What should you use?

You are implementing a method named GetValidPhoneNumbers. The GetValidPhoneNumbers() methodprocesses a list of string values that represent phone numbers.
The GetValidPhoneNumbers() method must return only phone numbers that are in a valid format.
You need to implement the GetValidPhoneNumbers() method.
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 that uses multiple asynchronous tasks to optimize performance. The
application will be deployed in a distributed environment.
You need to retrieve the result of an asynchronous task that retrieves data from a web service.
The data will later be parsed by a separate task.
Which code segment should you use?

You are developing an application in C#.
The application uses exception handling on a method that is used to execute mathematical calculations by
using integer numbers.
You write the following catch blocks for the method (line numbers are included for reference only):

You need to add the following code to the method:

At which line should you insert the code?

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

To answer, complete each statement according to the information presented in the code.
Hot Area:

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

You are developing an application that includes the following code segment:

You need to implement the Open() method of each interface in a derived class named UseResources and call
the Open() method of each interface.
Which two code segments should you use? (Each correct answer presents part of the solution.
Choose two.)
