You need to minimize the completion time of the GetOutput() method.
Which code segment should you insert at line 06?

4. You are developing an application by using C#. The application includes an object that performs a long running process. You need to ensure that the garbage collector does not release the object's resources until the process completes.
Which garbage collector method should you use?

5. You are creating a class named Employee. The class exposes a string property named EmployeeType.
The following code segment defines the Employee class. (Line numbers are included for reference only.)


The EmployeeType property value must be accessed and modified only by code within the Employee class or within a class derived from the Employee class. You need to ensure that the implementation of the EmployeeType property meets the requirements.
Which two actions should you perform? (Each correct answer represents part of the complete solution. Choose two.)

6. You are implementing a method named Calculate that performs conversions between value types and reference types.
The following code segment implements the method. (Line numbers are included for reference only.)


You need to ensure that the application does not throw exceptions on invalid conversions.
Which code segment should you insert at line 04?

7. You are creating a console application by using C#. You need to access the application assembly.
Which code segment should you use?

8. You use the Task.Run() method to launch a long-running data processing operation. The data processing operation often fails in times of heavy network congestion. If the data processing operation fails, a second operation must clean up any results of the first operation. You need to ensure that the second operation is invoked only if the data processing operation throws an unhandled exception.
What should you do?

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


Leases are restricted to a maximum term of 5 years. The application must send a notification message if a lease request exceeds 5 years. You need to implement the notification mechanism.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

10. You are developing an application that uses structured exception handling. The application includes a class named ExceptionLogger.
The ExceptionLogger class implements a method named LogException by using the following code segment:
public static void LogException(Exception ex)
You have the following requirements:
• Log all exceptions by using the LogException() method of the ExceptionLogger class.
• Rethrow the original exception, including the entire exception stack.
You need to meet the requirements.
Which code segment should you use?

11. You are developing an application that includes a class named UserTracker.
The application includes the following code segment. (Line numbers are included for reference only.)


You need to add a user to the UserTracker instance.
What should you do?

12. You are adding a public method named UpdateScore to a public class named ScoreCard.
The code region that updates the score field must meet the following requirements:
• It must be accessed by only one thread at a time.
• It must not be vulnerable to a deadlock situation.
You need to implement the UpdateScore() method.
What should you do?

13. You are developing a C# application that has a requirement to validate some string input data by using the Regex class. The application includes a method named ContainsHyperlink. The ContainsHyperlink() method will verify the presence of a URI and surrounding markup.
The following code segment defines the ContainsHyperlink() method. (Line numbers are included for reference only.)


The expression patterns used for each validation function are constant. You need to ensure that the expression syntax is evaluated only once when the Regex object is initially instantiated.
Which code segment should you insert at line 04?

14. You are developing an application by using C#.
You have the following requirements:
• Support 32-bit and 64-bit system configurations.
• Include pre-processor directives that are specific to the system configuration.
• Deploy an application version that includes both system configurations to testers.
• Ensure that stack traces include accurate line numbers.
You need to configure the project to avoid changing individual configuration settings every time you deploy the application to testers.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

15. You are developing a method named CreateCounters that will create performance counters for an application.
The method includes the following code. (Line numbers are included for reference only.)


You need to ensure that Counter1 is available for use in Windows Performance Monitor (PerfMon).
Which code segment should you insert at line 16?

16. You are developing an application that will transmit large amounts of data between a client computer and a server. You need to ensure the validity of the data by using a cryptographic hashing algorithm.
Which algorithm should you use?

17. You are developing an assembly that will be used by multiple applications. You need to install the assembly in the Global Assembly Cache (GAC).
Which two actions can you perform to achieve this goal? (Each correct answer presents a complete solution. Choose two.)

18. You are debugging an application that calculates loan interest.
The application includes the following code. (Line numbers are included for reference only.)


You need to ensure that the debugger breaks execution within the CalculateInterest() method when the loanAmount variable is less than or equal to zero in all builds of the application.
What should you do?

19. You are developing an application that accepts the input of dates from the user. Users enter the date in their local format. The date entered by the user is stored in a string variable named inputDate. The valid date value must be placed in a DateTime variable named validatedDate. You need to validate the entered date and convert it to Coordinated Universal Time (UTC). The code must not cause an exception to be thrown.
Which code segment should you use?

20. You are developing an application by using C#. You provide a public key to the development team during development. You need to specify that the assembly is not fully signed when it is built.
Which two assembly attributes should you include in the source code? (Each correct answer presents part of the solution. Choose two.)
