• Question 221:

  An application includes a class named Person. The Person class includes a method named GetData.

  You need to ensure that the GetData() method can be used only by the Person class and not by any class derived from the Person class.

  Which access modifier should you use for the GetData() method?

  A. Internal
  B. Protected
  C. Private
  D. Protected internal
  E. Public
  C. Private

  ---

  The GetData() method should be private. It would then only be visible within the Person class.

• Question 222:

  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?

  A. System.Security.Cryptography.DES
  B. System.Security.Cryptography.Aes
  C. System.Security.Cryptography.TripleDES
  D. System.Security.Cryptography.RC2
  B. System.Security.Cryptography.Aes

  ---

  Advanced Encryption Standard (AES) has been adopted by the U.S. government and is now used worldwide. It supersedes the Data Encryption Standard (DES). AES key sizes are 128, 192 or 256 bits.

  Incorrect:

  DES, 3DES, and RC2 are all less secure.

• Question 223:

  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?

  

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  B. Option B

• Question 224:

  You are developing an assembly.

  You plan to sign the assembly when the assembly is developed.

  You need to reserve space in the assembly for the signature.

  What should you do?

  A. Run the Assembly Linker tool from the Windows Software Development Kit (Windows SDK).
  B. Run the Strong Name tool from the Windows Software Development Kit (Windows SDK).
  C. Add the AssemblySignatureKeyAttribute attribute the assembly.
  D. Add the AssemblyDelaySignAttribute attribute to the assembly.
  D. Add the AssemblyDelaySignAttribute attribute to the assembly.

  ---

  The AssemblyDelaySignAttribute class specifies that the assembly is not fully signed when created.

• Question 225:

  DRAG DROP

  You have the following code:

  

  You need to deserialize the stream1 parameter into the CompanyInfo class.

  How should you c

  omplete the code? To answer, drag the appropriate code elements to the correct targets. Each code element may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

  NOTE: Each correct selection is worth one point.

• Question 226:

  You have an assembly named Assembly1 that is written in C#. Assembly1 has a method named Method1.

  You add a new method named Method2 to Assembly1. Method2 is a newer version of Method1 and must be used by applications in the future.

  You need to ensure that if a developer builds a project that uses Method1, the developer is notified that Method1 is deprecated.

  What should you do?

  A. Set an #if DEPRECATED preprocessor directive above Method1. Set a #endif preprocessor directive after Method1.
  B. Set a #pragma warning disable preprocessor inside of Method1.
  C. Mark Method1 with an ObsoleteAttribute attribute.
  D. Mark Method1 with a Conditional attribute that is set to WARNING.
  C. Mark Method1 with an ObsoleteAttribute attribute.

• Question 228:

  DRAG DROP

  You are creating a method by using C#. The method will accept three strings as parameters. The parameters are named string1, string2, and string3. The parameter values range from 5,000 to 15,000 characters.

  The method will have the following signature.

  

  You need to ensure that StringCompare only returns true if string1 concatenated to string2 is equal to string3. The comparison must be case-insensitive. The solution must ensure that StringCompare executes as quickly as possible.

  Which three code blocks should you use to develop the solution? To answer, move the appropriate code blocks from the list of code blocks to the answer area and arrange them in the correct order.
