QUESTION 1
You are creating a Windows Forms application by using the .NET Framework 3.5. You
create a new form in your application. You add a PrintDocument control named pntDoc to
the form.To support the print functionality, you write the following code segment in the
application. (Line numbers are included for reference only.)
01 pntDoc.BeginPrint += new PrintEventHandler(PrintDoc_BeginPrint);
02 ...
03 bool canPrint = CheckPrintAccessControl();
04 if (!canPrint) {
05
06 }
07
You need to ensure that the following requirements are met:
When the user has no print access, font and file stream initializations are not
executed and the print operation is cancelled.
Print operations are logged whether or not the user has print access.
What should you do?

A. Add the following code segment at line 05.
pntDoc.BeginPrint -= new PrintEventHandler(PrintDoc_BeginPrint);
pntDoc.BeginPrint += new PrintEventHandler((obj, args) => args.Cancel = true);
Add the following code segment at line 07.
pntDoc.BeginPrint += new PrintEventHandler((obj1, args1) => LogPrintOperation());
B. Add the following code segment at line 05.
pntDoc.BeginPrint += new PrintEventHandler(delegate(object obj, PrintEventArgs args){});
Add the following code segment at line 07.
pntDoc.BeginPrint -= new PrintEventHandler(PrintDoc_BeginPrint);
pntDoc.BeginPrint += new PrintEventHandler((obj1, args1) => LogPrintOperation());
C. Add the following code segment at line 05.
pntDoc.BeginPrint -= new PrintEventHandler(PrintDoc_BeginPrint);
pntDoc.BeginPrint -= new PrintEventHandler(delegate(object obj, PrintEventArgs args){});
Add the following code segment at line 07.
pntDoc.BeginPrint -= new PrintEventHandler((obj1, args1) => LogPrintOperation());
D. Add the following code segment at line 05.
pntDoc.BeginPrint -= new PrintEventHandler((obj, args) => args.Cancel = true);
Add the following code segment at line 07.
pntDoc.BeginPrint += new PrintEventHandler(PrintDoc_BeginPrint);

pntDoc.BeginPrint -= new PrintEventHandler((obj1, args1) => LogPrintOperation());

Answer: A



QUESTION 2
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

Explanation/Reference:
Sequential Access is the most efficient for retrieval of BLOB data types.

QUESTION 3
You are creating a Windows Forms application by using the .NET Framework 3.5. You write
a code segment to connect to a Microsoft Access database and populate a DataSet.You need
to ensure that the application meets the following requirements:
It displays all database exceptions.
It logs all other exceptions by using the LogExceptionToFile.
Which code segment should you use?

A. try
{
categoryDataAdapter.Fill(dsCategory);
}
catch (SqlException ex)
{
MessageBox.Show(ex.Message, "Exception");
LogExceptionToFile(ex.Message);
}
B. try
{
categoryDataAdapter.Fill(dsCategory);
}
catch (SqlException ex)
{
MessageBox.Show(ex.Message, "Exception");
}
catch (Exception ex)
{ LogExceptionToFile(ex.Message);
}
C. try
{
categoryDataAdapter.Fill(dsCategory);
}
catch (OleDbException ex)
{
MessageBox.Show(ex.Message, "Exception");
}

catch (Exception ex)
{ LogExceptionToFile(ex.Message);
}
D. try
{
categoryDataAdapter.Fill(dsCategory);
}
catch (OleDbException ex)
{
MessageBox.Show(ex.Message, "Exception"); LogExceptionToFile(ex.Message);
}
