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 plan to deploy your ASP.NET application over XYZ’s intranet. The application uses data retrieved from a Microsoft SQL Server database. You want to use SQL Server connection pooling to optimize performance. You also need to protect confidential data stored on the server while minimizing administrative costs.

You need to configure security for your application. What should you do?

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 create an ASP.NET page that uses images to identify areas where a user can click to initiate actions. The users of the application use Internet Explorer.

You want to provide a pop-up window when the user moves the mouse pointer over an image. You want the pop-up window to display text that identifies the action that will be taken if the user clicks the image.
