You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an
application. The application connects to a Microsoft SQL Server database. The application has two DataTable objects that reference the Customers and Orders tables in the database. The application contains the following code segment. (Line numbers are included for reference only.)

01DataSet customerOrders = new DataSet();
02customerOrders.EnforceConstraints = true;
03ForeignKeyConstraint ordersFK = new ForeignKeyConstraint("ordersFK",
04customerOrders.Tables["Customers"].Columns["CustomerID"],
05customerOrders.Tables["Orders"].Columns["CustomerID"]);
06
07customerOrders.Tables["Orders"].Constraints.Add(ordersFK);

You need to ensure that an exception is thrown when you attempt to delete Customer records that have related Order records. Which code segment should you insert at line 06?

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 use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create a Windows Communication Foundation (WCF) Data Services service. You discover that when an application submits a PUT or DELETE request to the Data Services service, it receives an error. You need to ensure that the application can access the service. Which header and request type should you use in the application?

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 named dbo.

Documents that contains a column with large binary dat a. You are creating the Data Access Layer (DAL). You add the following code segment to query the dbo.Documents table. (Line numbers are included for reference only.)

01public void LoadDocuments(DbConnection cnx)
02{
03var cmd = cnx.CreateCommand();
04cmd.CommandText = "SELECT * FROM dbo.Documents";
05...
06cnx.Open();
07
08ReadDocument(reader); }

You need to ensure that data can be read as a stream. Which code segment should you insert at line 07?

You create English, French, and German versions of a test engine ASP.NET application you are developing for XYZ Inc. You have separate resource files for each language version.You need to deploy the appropriate resource file based on the language settings of the server. What should you do?

You are creating an ASP.NET application for XYZ. The company data is stored in a Microsoft SQL Server 6.5 database. Your application generates accounting summary reports based on transaction tables that contain million of rows.

You want your application to return each summary report as quickly as possible. You need to configure your application to connect to the database and retrieve the data in a away that achieves this goal.

What should you do?

You are creating an ASP.NET page for selling movie tickets. Users select a region, and then they select from a list of cities in that region. The site displays the names and locations of movie theaters in the city selected by the user.

Your company, XYZ Brothers, maintains a list of theaters in a database table that includes the city, name, and street address of each theater. You want to minimize the time required to retrieve and display the list of theater names after a user selects the region and city.

 What should you do?

You create an ASP.NET application to provide corporate news and information to XYZ’s employees. The application is used by employees in New Zealand.

Default.aspx has a Web Form label control named currentDateLabel. The Page.Load event handler for Default.aspx included the following line of code:
currentDateLabel.Text = DateTime.Now.ToString(“D”)

You need to ensure that the data is displayed correctly for employees in New Zealand. What should you do?
