Question: You develop a service application named FileService. You deploy the service application to multiple servers on your network.
You implement the following code segment. (Line numbers are included for reference only.)
01 Public Sub StartService(ByVal serverName As String)
02 Dim crtl As ServiceController = _
03 New ServiceController("FileService")
04 If crtl.Status = ServiceControllerStatus.Stopped Then
05 End If
06 End Sub
You need to develop a routine that will start FileService if it stops. The routine must start FileService on the server identified by the serverName input parameter.
Which two lines of code should you add to the code segment? (Each correct answer presents part of the solution. Choose two.)

A
Insert the following line of code between lines 04 and 05:
crtl.ExecuteCommand(0)

B
Insert the following line of code between lines 04 and 05:
crtl.Continue()

C
Insert the following line of code between lines 04 and 05:crtl.Start()

D
Insert the following line of code between lines 03 and 04:
crtl.ServiceName = serverName

E
Insert the following line of code between lines 03 and 04:
crtl.MachineName = serverName

F
Insert the following line of code between lines 03 and 04:
crtl.Site.Name = serverName

Question: You are testing a newly developed method named PersistToDB. This method accepts a parameter of type EventLogEntry. This method does not return a value.
You need to create a code segment that helps you to test the method. The code segment must read entries from the application log of local computers and then pass the entries on to the PersistToDB method. The code block must pass only events of type Error or Warning from the source MySource to the PersistToDB method. Which code segment should you use?

A
Dim myLog as New EventLog("Application", ".")
myLog.Source = "MySource"
For Each entry As EventLogEntry In myLog.Entries
If entry.EntryType = (EventLogEntryType.Error And _
EventLogEntryType.Warning)
Then PersistToDB(entry)
End If
Next

B
Dim myLog as New EventLog("Application", ".")
myLog.Source = "MySource"
For Each entry As EventLogEntry In myLog.Entries
If (entry.EntryType = EventLogEntryType.Error) Or _
(entry.EntryType = EventLogEntryType.Warning)
Then PersistToDB(entry)
End If
Next

C
Dim myLog as New EventLog("Application", ".")
For Each entry As EventLogEntry In myLog.Entries
If entry.Source = "MySource" Then
If (entry.EntryType = EventLogEntryType.Error) Or _
(entry.EntryType = EventLogEntryType.Warning) Then
PersistToDB(entry)
End If
End If
Next

D
Dim myLog As New EventLog("Application", ".")
For Each entry As EventLogEntry In myLog.Entries
If entry.Source = "MySource"
Then PersistToDB(entry)
End If

Question: You are developing an application that receives events asynchronously. You create a WqlEventQuery instance to specify the events and event conditions to which the application must respond. You also create a ManagementEventWatcher instance to subscribe to events matching the query. You need to identify the other actions you must perform before the application can receive events asynchronously. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

A
Create an event handler class that has a method that receives an ObjectReadyEventArgs parameter.

B
Set up a listener for events by using the Stopped event of the ManagementEventWatcher.

C
Use the WaitForNextEvent method of the ManagementEventWatcher to wait for the events.

D
Start listening for events by calling the Start method of the ManagementEventWatcher.

E
Set up a listener for events by using the EventArrived event of the ManagementEventWatcher.

Question: You are testing a method that examines a running process. This method returns an ArrayList containing the name and full path of all modules that are loaded by the process. You need to list the modules loaded by a process named C:\TestApps\Process1.exe. Which code segment should you use?
A
Dim ar As New ArrayList()
Dim procs As Process()
Dim modules As ProcessModuleCollection
procs = Process.GetProcesses("Process1")
If procs.Length > 0
Then modules = procs(0).Modules
For Each pm As ProcessModule In Modules
ar.Add(pm.ModuleName)
Next
End If

B
Dim ar As New ArrayList()

Question: You are creating a strong-named assembly named Assembly1 that will be used in multiple applications. Assembly1 will be rebuilt frequently during the development cycle. You need to ensure that each time the assembly is rebuilt it works correctly with each application that uses it. You need to configure the computer on which you develop Assembly1 such that each application uses the latest build of Assembly1. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

A
Create a DEVPATH environment variable that points to the build output directory for the strong- named assembly.

B
Add the following XML element to the machine configuration file: <dependentAssembly>
<assemblyIdentity name="Assembly1"
publicKeyToken="32ab4ba45e0a69a1"
language="en-US" version="*.*.*.*" />
<publisherPolicy apply="no" />
</dependentAssembly>

C
Add the following XML element to the configuration file of each application that uses the strong- named assembly:
<supportedRuntime version="*.*.*.*" />

D
Add the following XML element to the machine configuration file:
<developmentMode developerInstallation="true"/>

E
Add the following XML element to the configuration file of each application that uses the strong- named assembly:

<dependentAssembly>
<assemblyIdentity name="Assembly1"
publicKeyToken="32ab4ba45e0a69a1"
language="en-US" version="*.*.*.*" />
<bindingRedirect newVersion="*.*.*.*"/>

Question: You are using the Microsoft Visual Studio IDE to examine the output of a method that returns a string. You assign the output of the method to a string variable named fName. You need to write a code segment that prints the following on a single line
The message: "Test Failed: "
The value of fName if the value of fName does not equal "John"
You also need to ensure that the code segment simultaneously facilitates uninterrupted execution of the application. 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
