You use Visual Studio .NET to create a component named Request. This component includes a
method named AcceptEXRequest, which tries to process new user requests for services.
AcceptEXRequest calls a private function named Validate.
You must ensure that any exceptions encountered by Validate are bubbled up to the parent form
of Request. The parent form will then be responsible for handling the exceptions. You want to
accomplish this goal by writing the minimum amount of code.
What should you do?
A. Use the following code segment in AcceptESRequest:
this.Validate();
B. Use the following code segment in AcceptESRequest:
try { this.Validate(); }
catch(Exception ex) { throw ex;}
C. Use the following code segment in AcceptESRequest:
try { this.Validate();}
catch(Exception ex) {throw new Exception(“Exception in AcceptESRequest”, ex); }
D. Create a custom Exception class named RequestException by using the following code
segment:
public class RequestException:ApplicationException { public RequestException():base() {}
public RequestException
(string message):base(message) { }
public RequestException(string message, Exception inner):base(message, inner) { } }
In addition, use the following code segment in AcceptESRequest:
try {.this.Validate(); } catch(Exception ex) { throw new RequestException(“Exception in
AcceptESRequest”, ex); }

You develop a Windows-based application that enables to enter product sales. You add a
subroutine named XYZ.
You discover that XYZ sometimes raises an IOException during execution. To address this
problem you create two additional subroutines named LogError and CleanUp. These subroutines
are governed by the following rules:
• LogError must be called only when XYZ raises an exception.
• CleanUp must be called whenever XYZ is complete.
You must ensure that your application adheres to these rules. Which code segment should you
use?
A. try {
XYZ();
LogError();
}
catch (Exception e) {
CleanUp(e);
}
B. try {
XYZ();
}
catch (Exception e) {
LogError(e);
CleanUp();
}
C. try {
XYZ();
}
catch (Exception e) {
LogError(e);
}
finally {
CleanUp();
}
D. try {
XYZ();
} catch (Exception e) {
CleanUp(e);
}
finally {
LogError();
}

You develop an application that includes a Contact Class. The contact class is defined by the
following code:
public class Contact{
private string name;
public event EventHandler ContactSaved;
public string Name {
get {return name;}
set {name = value;}
}
public void Save () {
// Insert Save code.
// Now raise the event.
OnSave();
}
public virtual void OnSave() {
// Raise the event:
if (ContactSaved != null) {
ContactSaved(this, null);
}
}
}
You create a form named XYZForm. This form must include code to handle the ContactSaved
event raised by the Contact object. The Contact object will be initialized by a procedure named
CreateContact.
Which code segment should you use?
A. private void HandleContactSaved() {
// Insert event handling code.
}
private void CreateContact() {
Contact oContact = new Contact();
oContact.ContactSaved +=
new EventHandler(HandleContactSaved);
oContact.Name = “XYZ”;
oContact.Save();
}
B. private void HandleContactSaved(
object sender, EventArgs e) {
// Insert event handling code.
}.
private void CreateContact() {
Contact oContact = new Contact();
oContact.Name = “XYZ”;
oContact.Save(); }
C. private void HandleContactSaved(
object sender, EventArgs e) {
// Insert event handling code.
}
private void CreateContact() {
Contact oContact = new Contact();
oContact.ContactSaved +=
new EventHandler (HandleContactSaved);
oContact.Name = “XYZ”;
oContact.Save(); }
D. private void HandleContactSaved(Object sender, EventArgs e) {
// Insert event-handling code.
}
private void CreateContact() {
Contact oContact = new Contact();

You use Visual Studio .NET to develop a Windows-based application that interacts with a
Microsoft SQL Server database. Your application contains a form named CustomerForm. You
add the following design-time components to the form:
• SqlConnection object named XYZConnection.
• SqlDataAdapter object named XYZDataAdapter.
• DataSet object named XYZDataSet.
• Five TextBox controls to hold the values exposed by XYZDataSet.
At design time, you set the DataBindings properties of each TextBox control to the appropriate
column in the DataTable object of XYZDataSet. When you test the application, you can
successfully connect to the database. However, no data is displayed in any text boxes.
You need to modify your application code to ensure that data is displayed appropriately. Which
behavior should occur while the CustomerForm.Load event handler is running?
A. Execute the Add method of the TextBoxes DataBindings collection and pass in XYZDataSet.
B. Execute the BeginInit method of XYZDataSet.
C. Execute the Open method of XYZConnection.
D. Execute the FillSchema method of XYZDataAdapter and pass in XYZDataSet.
E. Execute the Fill method of XYZDataAdapter and pass in XYZDataSet. |

You use Visual Studio .NET to create a Windows-based application. The application includes a
form named XYZForm.
XYZForm contains 15 controls that enable users to set basic configuration options for the
application.
You design these controls to dynamically adjust when users resize XYZForm. The controls
automatically update their size and position on the form as the form is resized. The initial size of
the form should be 659 x 700 pixels..
If ConfigurationForm is resized to be smaller than 500 x 600 pixels, the controls will not be
displayed correctly. You must ensure that users cannot resize ConfigurationForm to be smaller
than 500 x 600 pixels.
Which two actions should you take to configure XYZForm? (Each correct answer presents part of
the solution. Choose two)
A. Set the MinimumSize property to “500,600”.
B. Set the MinimumSize property to “650,700”.
C. Set the MinimizeBox property to True.
D. Set the MaximumSize property to “500,600”.
E. Set the MaximumSize property to “650,700”.
F. Set the MaximumBox property to True.
G. Set the Size property to “500,600”.
H. Set the Size property to “650,700”.

File.Open(logfilePath, FileMode.Append));
TextWriterTraceListener oListener =
new TextWriterTraceListener(oWriter);
Trace.Listeners.Add(oListener);
try {
ProcessRecords();
}.
catch (Exception oEx) {
Trace.WriteLine(“Error: “ + oEx.Message;
