Microsoft TS: Accessing Data with Microsoft .NET Framework 4 Sample Questions:

1. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application.
The application connects to a Microsoft SQL Server database and contains a LINQ to SQL data model.
The data model contains a function named createCustomer that calls a stored procedure.
The stored procedure is also named createCustomer. The createCustomer function has the following
signature.
createCustomer (Guid customerID, String customerName, String address1)
The application contains the following code segment. (Line numbers are included for reference only.)
01 CustomDataContext context = new CustomDataContext(); 02 Guid userID = Guid.NewGuid();
03 String address1 = "1 Main Steet";
04 String name = "Marc";
05 ...
You need to use the createCustomer stored procedure to add a customer to the database. Which code segment should you insert at line 05?

A) context.ExecuteCommand("createCustomer", customer); Customer customer = new Customer() { ID = userID, Address1 = address1, Name = customer1, };
B) context.ExecuteQuery(typeof(Customer), "createCustomer", customer);
C) context.ExecuteCommand("createCustomer", userID, customer1, address1); Customer customer = new Customer() { ID = userID, Address1 = address1, Name = customer1, };
D) context.createCustomer(userID, customer1, address1);

2. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application.

A) DataSet ds = new DataSet(); ds.ExtendedProperties["RowCount"] = 10; ds.ExtendedProperties["RowIndex"] = 0; adapter.Fill(ds);
B) DataSet ds = new DataSet(); DataTable dt = ds.Tables.Add("Product"); adapter.Fill(0, 10, dt);
C) DataSet ds = new DataSet(); DataTable dt = ds.Tables.Add("Product"); dt.ExtendedProperties["RowCount"] = 10; dt.ExtendedProperties["RowIndex"] = 0; adapter.Fill(dt);
D) DataSet ds = new DataSet(); adapter.Fill(ds, 0, 10, "Product");

4. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create a Windows Forms
application.
