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

1. You use Microsoft .NET Framework 4.0 to develop an application that connects to a Microsoft SQL Server
2008 database.
You add the following table to the database.
CREATE TABLE Orders( ID numeric(18, 0) NOT NULL, OrderName varchar(50) NULL, OrderTime time(7) NULL, OrderDate date NULL)
You write the following code to retrieve data from the OrderTime column. (Line numbers are included for reference only.)
01 SqlConnection conn = new SqlConnection("...");
02 conn.Open();
03 SqlCommand cmd = new SqlCommand("SELECT ID, OrderTime FROM Orders", conn);
04 SqlDataReader rdr = cmd.ExecuteReader();
05 ....
06 while(rdr.Read())
07 {
08 ....
09 }
You need to retrieve the OrderTime data from the database. Which code segment should you insert at line 08?

A) string time = (string)rdr[1];
B) TimeSpan time = (TimeSpan)rdr[1];
C) DateTime time = (DateTime)rdr[1];
D) Timer time = (Timer)rdr[1];

2. You use Microsoft .NET Framework 4 to develop an application that connects to a Microsoft SQL Server
2008 database.
You add the following stored procedure to the database.
CREATE PROCEDURE [dbo].[InsertTag] @Name nvarchar (15)
AS INSERT INTO [dbo].[Tags] (Name) VALUES(@Name) RETURN @@ROWCOUNT
You need to invoke the stored procedure by using an open SqlConnection named conn. Which code segment should you use?

A) SqlCommand cmd = new SqlCommand("InsertTag", conn); cmd.CommandType = CommandType.StoredProcedure; cmd.Parameters.AddWithValue("@Name", "New Tag 1"); cmd.ExecuteNonQuery();
B) SqlCommand cmd = new SqlCommand("EXEC InsertTag", conn); cmd.CommandType = CommandType.StoredProcedure; cmd.Parameters.AddWithValue("@Name", "New Tag 1"); cmd.ExecuteNonQuery();
C) SqlCommand cmd = new SqlCommand("InsertTag", conn); cmd.CommandType = CommandType.Text; cmd.Parameters.AddWithValue("@Name", "New Tag 1"); cmd.ExecuteNonQuery();
D) SqlCommand cmd = new SqlCommand("EXEC InsertTag", conn); cmd.CommandType = CommandType.Text; cmd.Parameters.AddWithValue("@Name", "New Tag 1"); cmd.ExecuteNonQuery();

3. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to develop an application that uses the ADO.NET Entity Framework to model entities. You create an entity model as shown in the following diagram.

C) Modify the .edmx file to include the following line of code: <NavigationProperty Name="Type" FromRole="EmployeeType" ToRole="Contractor" />
D) Use the Entity Data Model Designer to set up a referential constraint between the primary key of the Contractor class and EmployeeType.

5. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create a Windows
Communication
