You are developing a method named GetHash that will return a hash value for a file. The method
includes the following code. (Line numbers are included for reference only.)

You need to return the cryptographic hash of the bytes contained in the fileBytes variable.
Which code segment should you insert at line 05?

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.)

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?

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.

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?

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 implementing a method named GetValidPhoneNumbers. The GetValidPhoneNumbers()
method processes 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.)

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.)

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

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?
