You use Visual Studio .NET to develop a Windows-Bases application named PatTrac. It uses the
security class libraries of the .NET Framework to implement security. PatTrac will run within the
context of a Windows 2000 domain named MedicalOffice. Calls to a remote Windows 2000
domain named XYZ will occur during the execution of PatTrac.
You want PatTrac to log on to the XYZ domain by using a generic user account.
What should you do?
A. Create a new instance of the WindowsImpersonationContext class by calling the Impersonate
method of the Genericidentity object and passing the token of the user whom you want to
impersonate.
B. Create a new instance of the WindowsImpersonationContext class by calling the Impersonate
method of the WindowsIdentify object and passing the token of the user whom you want to
impersonate.
C. Create a new instance of the ZoneIdentifyPermission class by calling the Impersonate method
of the GenericPrincipal object and passing the token of the user whom you want to
impersonate.
D. Create a new instance of the ZoneIdentifyPermission class by calling the Impersonate method
of the WindowsPrincipal object and passing the token of the user whom you want to
impersonate.

You development team used Visual Studio .NET to create an accounting application, which
contains a class named XYZAccounts. This class instantiates several classes from a COM
component that was created by using Visual Basic 6.0. Each COM component class includes a
custom method named ShutDownObject that must be called before terminating references to the
class.
Software testers report that the COM component appears to remain in memory after the
application terminates. You must ensure that the ShutDownObject method of each COM
component class is called before XYZAccounts is terminated.
What should you do?
A. Add code to the Terminate event of XYZAccounts to call the ShutDownObject method of each
COM component class.
B. Find each location in your code where a reference to XYZAccounts is set to null or goes out of
scope.
Add code after each instance to manually invoke the Visual Studio .NET garbage collector.
C. Add a destructor to XYZAccounts.
Add code to the destructor to call the ShutDownObject method of each COM component
class.
D. Add the procedure private void Finally() to XYZAccounts.
Add code to the procedure to call the ShutDownObject method of each COM component
class.

You work as a software developer at Comapany.net You use Visual Studio .NET to create an
application that tracks support incidents for your technical support department at Comapany.net.
You implement the Trace class to write information about run-time errors in a local log file. You
also implement a TraceSwitch object named ComapanySwitch, which can turn Trace logging on
and off as needed. To maximize application performance, you ensure that ComapanySwitch is
disabled by default.
You set your Configuration Manager to Release. You compile the application and deploy it to a
shared folder on your company intranet. Fifty users access the application from a shortcut on
their desktops. One user receives error messages while running the application. You device to
enable verbose trace logging within the application for that user. You must ensure that you do not
affect application performance for the other users.
Which action or actions should you take? (Choose all that apply)
A. Set your Configuration Manager to Debug.
Compile your application and deploy it locally on the user’s computer.
Create a new shortcut on the user’s desktop to access the local copy of the application.
B. Copy the deployed version of the application from the shared folder.
Deploy it locally on the user’s computer.
Create a new desktop shortcut on the user’s desktop to access the local copy of the
application.

You develop an application that invokes a procedure named ProcessRecords. You implement the
Trace class to log any errors thrown by ProcessRecords. You direct the Trace output to a local
log file named ErrorLog.txt by using the following code segment:
StreamWriter oWriter = new StreamWriter(
File.Open(logfilePath, FileMode.Append));
TextWriterTraceListener oListener =
new TextWriterTraceListener(oWriter);
Trace.Listeners.Add(oListener);
try {
ProcessRecords();
}.
catch (Exception oEx) {
Trace.WriteLine(“Error: “ + oEx.Message;
}
finally {
}
Now you need to add code to your finally construct to write all output in the ErrorLog.txt file and
then close the file. You want to write the minimum amount of code to achieve this goal.
Which code segment should you use?
A. oWriter.Close();
B. Trace.Flush(); oWriter.Close();
C. Trace.AutoFlush = true; oWriter.Close();
D. oWriter.AutoFlush = true; oWriter.Close();

You create a Windows Form named XYZForm. The form enables users to maintain database
records in a table named XYZ.
You need to add several pairs of controls to XYZForm. You must fulfill the following
requirements:.
• Each pair of controls must represent one column in the XYZ table.
• Each pair must consist of a TextBox control and a Label control.
• The LostFocus event of each TextBox control must call a procedure named UpdateDatabase.
• Additional forms similar to XYZForm must be created for other tables in the database.
• Application performance must be optimized.
• The amount of necessary code must be minimized.
What should you do?
A. Create and select a TextBox control and a Label control.
Write the appropriate code in the LostFocus event of the TextBox control.
Repeatedly copy and paste the controls into XYZForm until every column in the XYZ table has
a pair of controls.
Repeat this process for the other forms.
B. Add a TextBox control and a Label controls to XYZForm.
Write the appropriate code in the LostFocus event of the TextBox control.
Create a control array form the TextBox control and the Label control.
At run time, add additional pairs of controls to the control array until every column in the XYZ
table has a pair of controls.
Repeat this process for the other forms.
C. Create a new user control that includes a TextBox control and a Label control.
Write the appropriate code in the LostFocus event of the TextBox control.
For each column in the XYZ table, add one instance of the user control to the XYZForm.
Repeat this process for the other forms.
D. Create a new ActiveX control that includes a TextBox control and a Label control.
For each column in the XYZ table, add one instance of the ActiveX control to XYZForm.
