• Question 182:

  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?

  A. HMACSHA256
  B. RNGCryptoServiceProvider
  C. DES
  D. Aes
  E. RSA
  F. Rfc2898DeriveBytes
  A. HMACSHA256

  ---

  The .NET Framework provides the following classes that implement hashing algorithms:

  HMACSHA1.

  MACTripleDES.

  MD5CryptoServiceProvider.

  RIPEMD160.

  SHA1Managed.

  SHA256Managed.

  SHA384Managed.

  SHA512Managed.

  HMAC variants of all of the Secure Hash Algorithm (SHA), Message Digest 5 (MD5), and RIPEMD-160 algorithms.

  CryptoServiceProvider implementations (managed code wrappers) of all the SHA algorithms.

  Cryptography Next Generation (CNG) implementations of all the MD5 and SHA algorithms.

• Question 183:

  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.

• Question 184:

  You are creating a console application named App1.

  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?

  

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

  The JavaScriptSerializer Class Provides serialization and deserialization functionality for AJAX-enabled applications.

  The JavaScriptSerializer class is used internally by the asynchronous communication layer to serialize and deserialize the data that is passed between the browser and the Web server. You cannot access that instance of the serializer.

  However, this class exposes a public API. Therefore, you can use the class when you want to work with JavaScript Object Notation (JSON) in managed code.

• Question 185:

  DRAG DROP

  You are developing a class named Temperature.

  You need to ensure that collections of Temperature objects are sortable.

  You have the following code:

  

  Which code segments should you include in Target 1, Target 2 and Target 3 to complete the code? (To answer, drag the appropriate code segments to the correct targets in the answer area. Each code segment 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.)

  Select and Place:

  

  

• Question 186:

  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.)

  A. AssemblyFlagsAttribute
  B. AssemblyKeyFileAttribute
  C. AssemblyConfigurationAttribute
  D. AssemblyDelaySignAttribute
  B. AssemblyKeyFileAttribute
  D. AssemblyDelaySignAttribute

  ---

  *

  AssemblyDelaySignAttribute

  Specifies that the assembly is not fully signed when created.

  *

  The following code example shows the use of the AssemblyDelaySignAttribute attribute with the AssemblyKeyFileAttribute.

  using System;

  using System.Reflection;

  [assembly:AssemblyKeyFileAttribute("TestPublicKey.snk")] [assembly:AssemblyDelaySignAttribute(true)]

  namespace DelaySign

  {

  public class Test { }

  }

• Question 187:

  You are developing an application that uses the Microsoft ADO.NET Entity Framework to retrieve order information from a Microsoft SQL Server database. The application includes the following code. (Line numbers are included for reference only.)

  

  The application must meet the following requirements:

  Return only orders that have an OrderDate value other than null. Return only orders that were placed in the year specified in the year parameter.

  You need to ensure that the application meets the requirements. Which code segment should you insert at line 08?

  

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

• Question 188:

  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?

  A. ReRegisterForFinalize()
  B. SuppressFinalize()
  C. Collect()
  D. WaitForFullGCApproach()
  B. SuppressFinalize()

  ---

  You can use the SuppressFinalize method in a resource class to prevent a redundant garbage collection from being called. Reference: GC.SuppressFinalize Method (Object) https://msdn.microsoft.com/en-us/library/system.gc.suppressfinalize(v=vs.110).aspx

• Question 189:

  public static void Log(Exception ex) { }

  You have the following requirements:

  Log all exceptions by using the Log() method of the Logger class. Rethrow the original exception, including the entire exception stack.

  You need to meet the requirements. Which code segment should you use?

  

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