1. You use Visual Studio .NET to create an application that interacts with a Microsoft SQL Server
database. You create aSQL Server stored procedure named CustOrderDetails and save it in the
database. Other developers on your teamfrequently debug other stored procedures.You need to verify
that your stored procedure is performing correctly. You need to step through CustOrderDetails inside the
Visual Studio .NET debugger. What should you do?
A. Run CustOrderDetails by using the Visual Studio .NET Server Explorer.
B. Step into CustOrderDetails by using the Visual Studio .NET Server Explorer.
C. From the Command window, use Ctrl+E to run CustOrderDetails.
D. Move CustOrderDetails from the Visual Studio .NET Server Explorer window to a Windows Form. Run
theapplication in Debug mode and step through CustOrderDetails.
Answer: B
2. You use Visual Studio .NET to create a Windows-based data management application named MyApp.
You implementthe following code segment: Dim oSwitch As New _TraceSwitch(”MySwitch”, “My
TraceSwitch”) Dim oWriter As New _IO.StreamWriter(IO.File.Open(”c:\MyApp.txt”, _
IO.FileMode.Append)) Dim oListener As New _TextWriterTraceListener(oWriter)
Trace.Listeners.Add(oListener) TryCustomerUpdate() Catch oEx As Exception
Trace.WriteLineIf(oSwitch.TraceError, _ “Error: ” & oEx.Message) Finally T Trace.Listeners.Clear()
oWriter.Close() oWriter = Nothing
End Try You compile a debug version of the application and deploy it to a user’s computer. The user
reports errors, which are generated within the CustomerUpdate procedure.You decide to enable logging
of the error messages generated by CustomerUpdate. You want to use the minimumamount of
administrative effort. What should you do?
A. Start the application with the following command line: /TRACE MySwitch 1.
B. Start the application with the following command line: /d:TRACE=True.
C. Start the application with the following command line: /XML <switch=”MySwitch” value=”1″>
D. Create an environment variable on the user’s computer. Name the variable MySwitch and assign it a
value of 1.
E. Edit your application’s .config file to set the value of MySwitch to 1.
Answer: E
3. You develop a Windows-based application named CustOrders. You implement the Trace object within
your application code. You will use this object to record application information, such as errors and
performance data, in a log file. You must have the ability to enable and disable Trace logging. This
functionality must involve the minimum amount of administrative effort. What should you do?
The safer , easier way to help you pass any IT exams.
3 / 6
A. Create a Boolean constant in your application named TraceLogging and set it to False . Each time your
code usesTrace logging, use a If Then statement to evaluate your #TraceLogging constant.
B. On each computer that will host your application, create an environment variable named
CustOrders.Trace. Set theenvironment variable to True when you want to enable Trace logging. Set it to
False when you want to disable Trace logging.
C. On each computer that will host your application, edit the shortcut used to start your application.
Add/d:TRACE=True to the Target property.
D. Use the TraceSwitch class within your code. Each time your code uses Trace logging, consult the
TraceSwitch level toverify whether to log information. Change the TraceSwitch level by editing your
application’s .config file.
Answer: D
4. Your project team uses Visual Studio .NET to create an accounting application. Each team member
uses the Writemethod of both the Debug class and the Trace class to record information about application
execution in the Windows2000 event log.
You are performing integration testing for the application. You need to ensure that only one entry is added
to the eventlog each time a call is made to the Write method of either the Debug class or the Trace
class.What are two possible code segments for you to use? (Each correct
Answer presents a complete solution. Choose two.)
A. Dim myTraceListener As New _ EventLogTraceListener(”myEventLogSource”)
Trace.Listeners.Add(myTraceListener)
B. Dim myDebugListener As New _ EventLogTraceListener(”myEventLogSource”)
Debug.Listeners.Add(myDebugListener)
C. Dim myTraceListener As New _ EventLogTraceListener(”myEventLogSource”)
Debug.Listeners.Add(myTraceListener) Trace.Listeners.Add(myTraceListener)
D. Dim myDebugListener As New _ EventLogTraceListener(”myEventLogSource”) Dim myTraceListener
As New _EventLogTraceListener(”myEventLogSource”) Debug.Listeners.Add(myDebugListener)
Trace.Listeners.Add(myTraceListener)
Answer: AB
5. You are maintaining a Visual Studio .NET sales application that was created by another developer. The
applicationfunctions as expected for several months. Then users report that it sometimes calculates tax
amounts incorrectly. An examination of the source code leads you to suspect that the errors are caused
by a function named CalculateSalesTax.To test your hypothesis, you place a breakpoint on the following
line of code:decTax = CalculateSalesTax(decRate, decSaleAmount) However, when you run the
application to create a test invoice, the breakpoint is not invoked.How should you correct this problem?
A. Select Enable All Breakpoints from the Debug menu.
B. Select Configuration Manager from the Build menu. Set the Active Solution Configuration option to
Debug . Set theConfiguration property of the project to Debug .
C. Select Options from the Tools menu and then select the General object from the Debugging folder.
Choose the option In break mode, only stop execution of the current process .
D. Select Exceptions from the Debug menu. Under the heading If the exception is not handled , select
Break into theDebugger .
Answer: B
6. Your development team uses Visual Studio .NET to create an accounting application, which contains a
class named SupplierAccounts. 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
beforeterminating 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 SupplierAccounts is terminated. What should you do?
A. Add code to the Terminate event of SupplierAccounts to call the ShutDownObject method of each
COM component
class.
B. Find each location in your code where a reference to SupplierAccounts is set to Nothing or goes out of
scope. Addcode after each instance to manually invoke the Visual Studio .NET garbage collector.
C. Add the procedure Protected Overrides Finalize() to SupplierAccounts. Add code to the procedure to
call theShutDownObject method of each COM component class.
D. Add the procedure Private Sub Finally() to SupplierAccounts. Add code to the procedure to call the
ShutDownObject method of each COM component class.
Answer: C
