Microsoft UPG:Transition MCPD.NET Frmwrk 3.5 Web Dev to 4 Web Dev Sample Questions:

Question 1

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. You use the ADO.NET Entity Data Model (EDM) to define a Customer entity. You need to add a new Customer to the data store without setting all the customer's properties. What should you do?

A. Override the SaveChanges method for the Customer object.

Question 2

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The application connects to a Microsoft SQL Server 2008 database. The database includes a table that contains information about all the employees. The database table has a field named EmployeeType that identifies whether an employee is a Contractor or a Permanent employee. You declare the Employee entity base type. You create a new Association entity named Contractor that inherits the Employee base type. You need to ensure that all Contractors are bound to the Contractor class. What should you do?

A. Modify the .edmx file to include the following line of code. <NavigationProperty Name="Type" FromRole="EmployeeType" ToRole="Contractor" />
B. Use the Entity Data Model Designer to set up a referential constraint between the primary key of the Contractor class and EmployeeType.
C. Use the Entity Data Model Designer to set up an association between the Contractor class and EmployeeType.
D. Modify the .edmx file to include the following line of code. <Condition ColumnName="EmployeeType" Value="Contractor" />

Question 3

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The application uses the ADO.NET Entity Framework to model entities. The application allows users to make changes while disconnected from the data store. Changes are submitted to the data store by using the SubmitChanges method of the DataContext object. You receive an exception when you call the SubmitChanges method to submit entities that a user has changed in offline mode. You need to ensure that entities changed in offline mode can be successfully updated in the data store. What should you do?

A. Call the SaveChanges method of DataContext with a value of false.

Web application and edit those images by using utilities provided by the application. Some utilities are
processor intensive and should be offloaded to a Graphics Processing Unit (GPU). Other utilities require
the use of proprietary algorithms that must be performed on the server.
You need to design a solution for minimizing bandwidth usage and Web server response times during
image processing, while providing a responsive application.
