QUESTION 107
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to develop an application. A file named books.xml contains the following XML.
<bib>
   <book title=”Programming in Unix” year=”1992″>

QUESTION 109
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.

cmd.CommandType = CommandType.Text;
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();

QUESTION 110
You use Microsoft .NET Framework 4 to develop an application that connects to a Microsoft SQL Server 2008 database.
The database contains a ClassStudent table that contains the StudentID for students who are enrolled in the classes.
You add the following stored procedure to the database.
CREATE PROCEDURE [dbo].[GetNumEnrolled]
   @ClassID INT,
   @NumEnrolled INT OUTPUT
AS BEGIN
   SET NOCOUNT ON
   SELECT @NumEnrolled = COUNT(StudentID)
      FROM ClassStudent
      WHERE (ClassID = @ClassID)
END
You write the following code. (Line numbers are included for reference only.)
01 private int GetNumberEnrolled(string classID)
02 {
03    using (SqlConnection conn = new SqlConnection(GetConnectionString())
04    {
05       SqlCommand cmd = new SqlCommand(“GetNumEnrolled”, conn);
06       cmd.CommandType = CommandType.StoredProcedure;
07       SqlParameter parClass = cmd.Parameters.Add(“@ClassID”, SqlDbType.Int, 4, “classID”);
08       SqlParameter parNum = cmd.Parameters.Add(“@NumEnrolled”, SqlDbType.Int);
09       …
10       conn.Open()
11       …
12    }
13 }
You need to ensure that the GetNumberEnrolled method returns the number of students who are enrolled for a specific class.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

A.    Insert the following code at line 09.
parNum.Direction = ParameterDirection.Input;
B.    Insert the following code at line 09.
parNum.Direction = ParameterDirection.Output;
C.    Insert the following code at line 11.
int numEnrolled = 0;
SqlDataReader reader = cmd.ExecuteReader();
while(reader.Read())
{
   numEnrolled = numEnrolled + (int)cmd.Parameters[“@NumEnrolled”].Value;
}
return numEnrolled;
D.    Insert the following code at line 11.
cmd.ExecuteNonQuery();
return (int)parNum.Value;
