1.
You are troubleshooting an ASP.NET Web application. System administrators have recently expanded your web farm from one to two servers. Users are periodically reporting an error message about invalid view state. You need to fix the problem. What should you do?
2.
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:
3.
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? (Each correct answer presents part of the solution. Choose
two.)
4.
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 user's login credentials cannot be stolen through a man-in-the- middle attack. Which approach should you recommend?
5.
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.)

7.
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?
01using (SqlConnection connection = new SqlConnection(cnnStr)) {
02connection.Open();
03SqlTransaction sqlTran = connection.BeginTransaction();
04SqlCommand command = connection.CreateCommand();
05command.Transaction = sqlTran;

8.
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?
9.
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?
10.
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 application uses DataContexts to query the database. You create a function that meets the following requirements: "Updates the Customer table on the database when a customer is marked as deleted. "Updates the related entries in other tables (CustomerAddress, CustomerContacts) by marking them as deleted. "Prevents consumer code from setting the Deleted column's value directly. You need to ensure that the function verifies that customers have no outstanding orders before they are marked as deleted. You also need to ensure that existing applications can use the update function without requiring changes in the code. What should you do?
