Microsoft UPGRADE: MCAD Skills to MCTS Web Apps Using MS.NET Framework Sample Questions:

1. You work as the developer in an IT company. Recently your company has a big customer. The customer runs a large supermarket chain. You're appointed to provide technical support for the customer. Now according to the customer requirement, you are creating an application. Custom authentication and role-based security will be used by the application. In order to make the runtime assign an unauthenticated principal object to each running thread, you have to write a code segment. In the options below, which code segment should you use?

A) AppDomain domain = AppDomain.CurrentDomain; domain.SetAppDomainPolicy( PolicyLevel.CreateAppDomainLevel());
B) AppDomain domain = AppDomain.CurrentDomain;domain.SetPrincipalPolicy(PrincipalPolicy.WindowsPrincipal);
C) AppDomain domain = AppDomain.CurrentDomain;domain.SetPrincipalPolicy( PrincipalPolicy.UnauthenticatedPrincipal);
D) AppDomain domain = AppDomain.CurrentDomain;domain.SetThreadPrincipal(new WindowsPrincipal(null));

2. You have just graduated from college, now you are serving the internship as the software developer in an international company. You develop an application where there's a method. You assign the output of the method to a string variable named fName. You are using the Microsoft Visual Studio 2005 IDE to examine the output of the method. You have to write a code segment. The code segment should print the following on a single line the message: "Test Failed: "
The value of fName if the value of fName does not equal "John"
Besides this, the code segment must facilitates uninterrupted execution of the application at the same time. You must make sure of this.
In the options below, which code segment should you use?

A) Debug.Assert(fName = "John", "Test Failed: ", fName)
B) Debug.WriteLineIf(fName <> "John", _ fName, "Test Failed")
C) If fName <> "John" Then Debug.Print("Test Failed: ") Debug.Print(fName)End If
D) If fName <> "John" Then Debug.WriteLine("Test Failed: ") Debug.WriteLine(fName)End If

3. You work as the developer in an IT company. Recently your company has a big client. The client runs a large supermarket chain. Your company appoints you to serve the client. Now you are examining the output of a method that returns a string by using the Microsoft Visual Studio 2005 IDE. You assign the output to a string variable named fName.
Now you have to write a code segment that prints the following on a single line. Besdes this, the code segment must simultaneously facilitates uninterrupted execution of the application.
The message: "Test Failed: "
The value of fName if the value of fName does not equal "John"
In the options below, which code segment should you use?

A) if (fName != "John") { Debug.WriteLine("Test Failed: "); Debug.WriteLine(fName);
}
B) Debug.WriteLineIf(fName != "John", fName, "Test Failed");
C) if (fName != "John") { Debug.Print("Test Failed: "); Debug.Print(fName); }
D) Debug.Assert(fName == "John", "Test Failed: ", fName);

4. You have just graduated from college, now you are serving the internship as the software developer in an international company. You're developing a new client application. An utility screen of the application displays a thermometer. The thermometer conveys the current status of processes being carried out by the application.
Look at the following exhibit, you have to draw a rectangle on the screen to serve as the background of the thermometer. The rectangle must be full of gradient shading.

In the options below, which code segment should you use?

A) Dim objRect As New Rectangle(10, 10, 450, 25)Dim objBrush As New LinearGradientBrush( _ objRect, Color.AliceBlue, Color.CornflowerBlue, _ LinearGradientMode.ForwardDiagonal)Dim objPen As New Pen(objBrush)Dim g As Graphics = myForm.CreateGraphicsg.FillRectangle(objBrush, objRect)
B) Dim objRect As New Rectangle(10, 10, 450, 25)Dim objBrush As New LinearGradientBrush( _ objRect, Color.AliceBlue, Color.CornflowerBlue, _ LinearGradientMode.ForwardDiagonal)Dim objPen As New Pen(objBrush)Dim g As Graphics = myForm.CreateGraphicsg.DrawRectangle(objPen, objRect)
C) Dim objRect As New Rectangle(10, 10, 450, 25)Dim objBrush As New SolidBrush(Color.AliceBlue)Dim objPen As New Pen(objBrush)Dim g As Graphics = myForm.CreateGraphicsg.DrawRectangle(objPen, objRect)
D) Dim objRect As New RectangleF(10.0F, 10.0F, 450.0F, 25.0F)Dim points() As System.Drawing.Point = _ {New Point(0, 0), New Point(110, 145)}Dim objBrush As New LinearGradientBrush( _ objRect, Color.AliceBlue, Color.CornflowerBlue, _ LinearGradientMode.ForwardDiagonal)Dim objPen As New Pen(objBrush)Dim g As Graphics = myForm.CreateGraphicsg.DrawPolygon(objPen, points)

5. You have just graduated from college, now you are serving the internship as the software developer in an international company. You are designing a .NET Framework 2.0 Web Application. You want the application to send messages by e-mail. There's an SMTP server which is named smtp.wikigo.com on the local subnet. You use a source address, [email protected], and [email protected], a target address, to test the application. In the options below, which code segment should you use to transmit the e-mail message?

A) Dim MailFrom As New MailAddress("[email protected]", "Me")Dim MailTo As New MailAddress("[email protected]", "You")Dim Message As New MailMessage(MailFrom, MailTo)Message.Subject = "Greetings"Message.Body = "Test"Dim Info As New SocketInformationDim Client As New Socket(Info)Dim Enc As New ASCIIEncodingDim Bytes() As Byte = Enc.GetBytes(Message.ToString)Client.Send(Bytes)
B) Dim MailFrom As New MailAddress("[email protected]", "Me")Dim MailTo As New MailAddress("[email protected]", "You")Dim Message As New MailMessage(MailFrom, MailTo)Message.Subject = "Greetings"Message.Body = "Test"Dim objClient As New SmtpClient("smtp.contoso.com")objClient.Send(Message)
C) Dim MailFrom As New MailAddress("[email protected]", "Me")Dim MailTo As New MailAddress("[email protected]", "You")Dim Message As New MailMessage(MailFrom, MailTo)Message.Subject = "Greetings"Message.Body = "Test"Message.Dispose()
D) Dim SMTPClient As String = "smtp.contoso.com"Dim MailFrom As String = "[email protected]"Dim MailTo As String = "[email protected]"Dim Subject As String = "Greetings"Dim Body As String = "Test"Dim Message As New MailMessage(MailFrom, MailTo, Subject, SMTPClient)
