Question: 5
You create an application by using the Microsoft .NET Framework 3.5 and Microsoft ADO.NET.
The application connects to a Microsoft SQL Server 2005 database. You write the following code
segment. (Line numbers are included for reference only.)

01 using (SqlConnection connection = new
SqlConnection(connectionString)) {
02 SqlCommand cmd = new SqlCommand(queryString, connection);
03 connection.Open();
04
05 while (sdrdr.Read()){
06 // use the data in the reader
07 }
08 }

You need to ensure that the memory is used efficiently when retrieving BLOBs from the
database. Which code segment should you insert at line 04?

A. SqlDataReader sdrdr = cmd.ExecuteReader();
B. SqlDataReader sdrdr = cmd.ExecuteReader(CommandBehavior.Default);
C. SqlDataReader sdrdr = cmd.ExecuteReader(CommandBehavior.SchemaOnly);
D. SqlDataReader sdrdr = cmd.ExecuteReader(CommandBehavior.SequentialAccess);

Answer: D

Question: 6
You create an application by using the Microsoft .NET Framework 3.5 and Microsoft ADO.NET.
The application uses a Microsoft SQL Server 2005 database. To open a connection to the
database, you write the following code segment. (Line numbers are included for reference only.)

01 private void GetOpenOrders() {
02 try {
03 //open SqlConnection and execute command.
04 }
05 catch (SqlException exp) {
06
07 }
08 }

The connection generates error messages and raises an exception. You use a ListBox control
named lstResults to display the error messages. You need to add a list item in the lstResults
control for each connection-related error message returned by the SqlConnection object. What
should you do?

A. Insert the following code segment at line 06. foreach (SqlError error in exp.Errors) {
lstResult.Items.Add(error.Message);}
B. Insert the following code segment at line 06. string[] errors = exp.Message.Split(new
char[]{‘,’});foreach (string error in errors) { if (error.IndexOf(“ConnectionError:”) > -1) {
lstResult.Items.Add(error); }}
C. Insert the following code segment at line 06. string[] errors = exp.StackTrace.Split(new
char[]{‘,’});foreach (string error in errors) { if (error.IndexOf(“ConnectionError:”) > -1) {
lstResult.Items.Add(error); }}
D. Insert the following code segment at line 06. LogException(exp.Message); Add the following
method to the application. private void LogException(Exception exp) { if (exp.InnerException !=
null) { LogException(exp.InnerException); } lstResult.Items.Add(exp.Message);}

Answer: A

Question: 7
You create an application by using the Microsoft .NET Framework 3.5 and Microsoft ADO.NET.
The application contains a DataSet class. The DataSet class contains two tables named Order
and OrderDetail as shown in the following exhibit. You add a DataColumn class named
OrderTotal to the Order table. You need to ensure that the OrderTotal column stores the sum of
the values in the LineTotal column of the OrderDetail table. Which expression string should you
use to set the Expression property of the OrderTotal column?
A. “Sum(OrderDetail.LineTotal)”
B. “Sum(Relationship.LineTotal)”
C. “Sum(Order_OrderDetail.LineTotal)”
D. “Sum(Child(Order_OrderDetail).LineTotal)”

Answer: D

Question: 8
You create an application by using the Microsoft .NET Framework 3.5 and Microsoft ADO.NET.
The application has a DataTable object named OrderDetailTable. The object has the following
columns:

ID
OrderID
ProductID
Quantity
LineTotal

The OrderDetailTable object is populated with data provided by a business partner. Some of the
records contain a null value in the LineTotal field and 0 in the Quantity field. You write the
following code segment. (Line numbers are included for reference only.)

01 DataColumn col = new DataColumn(“UnitPrice”, typeof(decimal));
02
03 OrderDetailTable.Columns.Add(col);

You need to add a DataColumn named UnitPrice to the OrderDetailTable object. Which line of
code should you insert at line 02?

A. col.Expression = “LineTotal/Quantity”;
B. col.Expression = “LineTotal/ISNULL(Quantity, 1)”;
C. col.Expression = “LineTotal.Value/ISNULL(Quantity.Value,1)”;
D. col.Expression = “iif(Quantity > 0, LineTotal/Quantity, 0)”;

Answer: D

Question: 9
You create an application by using the Microsoft .NET Framework 3.5 and Microsoft ADO.NET.
The application connects to a Microsoft SQL Server 2005 database. The connection string of the
application is defined in the following manner.
“Server=Prod;Database=WingtipToys;Integrated
Security=SSPI;Asynchronous Processing=true”
The application contains the following code segment. (Line numbers are included for reference
only.)

01 protected void UpdateData(SqlCommand cmd) {
02 cmd.Connection.Open();
03
04 lblResult.Text = “Updating …”;
05 }

The cmd object takes a long time to execute.
You need to ensure that the application continues to execute while cmd is executing.
What should you do?

A. Insert the following code segment at line 03. cmd.BeginExecuteNonQuery(new
AsyncCallback(UpdateComplete), cmd); Add the following code segment. private void
UpdateComplete (IAsyncResult ar) { int count = (int)ar.AsyncState; LogResults(count);}
B. Insert the following code segment at line 03. cmd.BeginExecuteNonQuery(new
AsyncCallback(UpdateComplete), cmd); Add the following code segment. private void
UpdateComplete (IAsyncResult ar) { SqlCommand cmd = (SqlCommand)ar.AsyncState; int
count = cmd.EndExecuteNonQuery(ar); LogResults(count);}
C. Insert the following code segment at line 03. cmd.StatementCompleted += new
StatementCompletedEventHandler(UpdateComplete);cmd.ExecuteNonQuery(); Add the
following code segment. private void UpdateComplete (object sender,
StatementCompletedEventArgs e) { int count = e.RecordCount; LogResults(count);}
D. Insert the following code segment at line 03. SqlNotificationRequest notification = new
SqlNotificationRequest(“UpdateComplete”, “”, 10000);cmd.Notification =
notification;cmd.ExecuteNonQuery(); Add the following code segment. private void
UpdateComplete(SqlNotificationRequest notice) { int count = int.Parse(notice.UserData);
LogResults(count);}

Answer: B

Question: 10
You create an application by using the Microsoft .NET Framework 3.5 and Microsoft ADO.NET.
The application contains a SqlDataAdapter object named daOrder. The SelectCommand property
of the daOrder object is set. You write the following code segment. (Line numbers are included
for reference only.)

01 private void ModifyDataAdapter() {
02
03 }

You need to ensure that the daOrder object can also handle updates.
Which code segment should you insert at line 02?

A. SqlCommandBuilder cb = new SqlCommandBuilder(daOrder);cb.RefreshSchema();
B. SqlCommandBuilder cb = new SqlCommandBuilder(daOrder);cb.SetAllValues = true;
C. SqlCommandBuilder cb = new SqlCommandBuilder(daOrder);daOrder.DeleteCommand =
cb.GetDeleteCommand();daOrder.InsertCommand =
cb.GetInsertCommand();daOrder.UpdateCommand = cb.GetUpdateCommand();
