• Question 52:

  You are developing an application. The application includes classes named Mammal and Animal and an interface named IAnimal.

  The Mammal class must meet the following requirements:

  It must either inherit from the Animal class or implement the IAnimal interface. It must be inheritable by other classes in the application.

  You need to ensure that the Mammal class meets the requirements.

  Which two code segments can you use to achieve this goal? (Each correct answer presents a complete solution. Choose two.)

  

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

  When applied to a class, the sealed modifier prevents other classes from inheriting from it. Reference: http://msdn.microsoft.com/en-us/library/88c54tsw(v=vs.110).aspx

  You need to ensure that the Customers class can be initialized by using the following code.

  

  Which code should you add to the application? To answer, drag the appropriate values to the correct targets. Each value 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.

• Question 54:

  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 OrderDate property or in a later year.

  You need to ensure that the application meets the requirements.

  Which code segment should you insert at line 08?

  A. Where order.OrderDate.Value != null andand order.OrderDate.Value.Year > = year
  B. Where order.OrderDate.Value = = null andand order.OrderDate.Value.Year = = year
  C. Where order.OrderDate.HasValue andand order.OrderDate.Value.Year = = year
  D. Where order.OrderDate.Value.Year = = year
  A. Where order.OrderDate.Value != null andand order.OrderDate.Value.Year > = year

  ---

  *For the requirement to use an OrderDate value other than null use: OrderDate.Value != null

  *For the requirement to use an OrderDate value for this year or a later year use: OrderDate.Value>= year

• Question 55:

  You are developing an application that retrieves customer data from a web service. The application stores the JSON messages returned from the web service in a string variable named CustomerAsJson. The variable is encoded as UTF-8. The application includes a class named Customer that is defined by the following code:

  

  You need to populate the Customer class with the data returned from the web service. Which code segment should you use?

  

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

• Question 56:

  HOTSPOT

  You are developing an application in C#.

  The application will display the temperature and the time at which the temperature was recorded. You have the following method (line numbers are included for reference only):

  

  You need to ensure that the message displayed in the lblMessage object shows the time formatted according to the following requirements:

  

  The time must be formatted as hour:minute AM/PM, for example 2:00 PM.

  

  The date must be formatted as month/day/year, for example 04/21/2013.

  

  The temperature must be formatted to have two decimal places, for example 23-45.

  Which code should you insert at line 04? (To answer, select the appropriate options in the answer area.)

  Hot Area:

  

  

• Question 57:

  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?

  A. Create a TaskCompletionSourceobject and call the TrySetException()method of the object.
  B. Create a task by calling the Task.ContinueWith() method.
  C. Examine the Task.Status property immediately after the call to the Task.Run() method.
  D. Create a task inside the existing Task.Run() method by using the AttachedToParentoption.
  B. Create a task by calling the Task.ContinueWith() method.

• Question 58:

  You are creating a class library that will be used in a web application. You need to ensure that the class library assembly is strongly named. What should you do?

  A. Use assembly attributes.
  B. Use the EdmGen.exe command-line tool.
  C. Set the configuration mode to Release when building the application.
  D. Use the gacutil.exe command-line tool.
  A. Use assembly attributes.

• Question 59:

  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.)

  A. Use the Assembly Registration tool (regasm.exe) to register the assembly and to copy the assembly to the GAC.
  B. Use the Strong Name tool (sn.exe) to copy the assembly into the GAC.
  C. Use Microsoft Register Server (regsvr32.exe) to add the assembly to the GAC.
  D. Use the Global Assembly Cache tool (gacutil.exe) to add the assembly to the GAC.
  E. Use Windows Installer 2.0 to add the assembly to the GAC.
  D. Use the Global Assembly Cache tool (gacutil.exe) to add the assembly to the GAC.
  E. Use Windows Installer 2.0 to add the assembly to the GAC.

  ---

  There are two ways to deploy an assembly into the global assembly cache:

  *

  Use an installer designed to work with the global assembly cache. This is the preferred option for installing assemblies into the global assembly cache.

  *

  Use a developer tool called the Global Assembly Cache tool (Gacutil.exe), provided by the Windows

  Software Development Kit (SDK).

  Note:

  In deployment scenarios, use Windows Installer 2.0 to install assemblies into the global assembly cache. Use the Global Assembly Cache tool only in development scenarios, because it does not provide assembly reference counting and

  other features provided when using the Windows Installer.

• Question 60:

  You are developing an application.

  The application contains the following code segment (line numbers are included for reference only):

  

  When you run the code, you receive the following error message: "Cannot implicitly convert type 'object'' to 'inf. An explicit conversion exists (are you missing a cast?)."

  You need to ensure that the code can be compiled.

  Which code should you use to replace line 05?

  A. var2 = ((List) array1) [0];
  B. var2 = array1[0].Equals(typeof(int));
  C. var2 = Convert.ToInt32(array1[0]);
  D. var2 = ((int[])array1)[0];
  C. var2 = Convert.ToInt32(array1[0]);

  ---

  The Convert.ToInt32 method converts a specified value to a 32-bit signed integer. Reference: https://msdn.microsoft.com/en-us/library/system.convert.toint32(v=vs.110).aspx
