You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The application uses the ADO.NET Entity Framework to manage customer and related order records. You add a new order for an existing customer. You need to associate the Order entity with the Customer entity. What should you do?

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The application connects to a Microsoft SQL Server database. You write the following code segment that executes two commands against the database within a transaction. (Line numbers are included for reference only.)

01using (SqlConnection connection = new SqlConnection(cnnStr)) {
02connection.Open();
03SqlTransaction sqlTran = connection.BeginTransaction();
04SqlCommand command = connection.CreateCommand();
05command.Transaction = sqlTran;
06try {
07command.CommandText = “INSERT INTO Production.ScrapReason(Name) VALUES(‘Wrong size’)”;
08command.ExecuteNonQuery();
09command.CommandText = “INSERT INTO Production.ScrapReason(Name) VALUES(‘Wrong color’)”;
10command.ExecuteNonQuery();
11
12}

You need to log error information if the transaction fails to commit or roll back.
Which code segment should you insert at line 11?

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 to entities while disconnected from the central data store.
You need to ensure that when the user connects to the central data store and retrieves new data, the application meets the following requirements:
Changes made to the local data store in disconnected mode are preserved.
Entities that have already been loaded into the local data store, but have not been modified by the user, are updated with the latest data.
What should you do?

You create a page in an ASP.NET Web application. The page retrieves and displays data from a Microsoft SQL Server database. You need to create a data source that can connect to the database. What are two possible ways to achieve this goal? (Each correct answer presents a complete solution. Choose two.)

You are implementing an ASP. NET MVC 2 Web application. You add a controller named CompanyController.
You need to modify the application to handle the URL path /company/info.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

You are designing an ASP.NET Web application by using Microsoft Visual Studio 2010. The Web application uses dynamic HTML (DHTML).
You need to ensure that the application functions properly on multiple browser platforms without requiring the installation of a client-side component.
Which two approaches could you recommend? (Each correct answer presents a complete solution. Choose two.)

You are designing an ASP.NET Web Forms application that uses a database containing user names and hashed passwords for authentication. The Web application includes a login form in which users type their user names and passwords.
You need to design a strategy to ensure that the users login credentials cannot be stolen through a man-in-the-middle attack.
Which approach should you recommend?

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create a Windows Communication Foundation (WCF) Data Services service. The service connects to a Microsoft SQL Server 2008 database. The service is hosted by an Internet Information Services (IIS) 6.0 server. You need to ensure that applications authenticate against user information stored in the database before the application is allowed to use the service. Which two actions should you perform?
