QUESTION 1:
You create a Windows service named CKService that quires a table named Orders in a Microsoft SQL Server database. You want CKService to check every 30 seconds for new rows in Orders.
You create the following method in myService:
Private Sub ProcessOrders(ByVal source As Object, ByVal eventArguments As
Timers.ElapsedEventArgs)
‘Code to process orders goes here. End Sub
You need to add additional code to CKService to invoke the ProcessOrders method. What should you do?
A. To the OnStart method, add the following code segment: Dim CKTimer As New Timers.Timer()
AddHandler CKTimer.Elapsed, AddressOfProcessOrders
CKTimer.Interval = 30000
CKTimer.Enabled = True
B. To the OnCustomCommand method, add the following code segment: Dim CKTimer As New Timers.Timer()
AddHandler CKTimer.Elapsed, AddressOf ProcessOrders
CKTimer.Interval = 30000
CKTimer.Enabled = True
C. To the OnStart method, add the following code segment: Dim CKTimer As New Timers.Timer()
AddHandler CKTimer.Elapsed, AddressOf ProcessOrders
CKTimer.Interval = 30000
CKTimer.AutoReset = True
D. To the OnCustomCommand method, add the following code segment: Dim CKTimer As New Timers.Timer()
AddHandler CKTimer.Elapsed, AddressOf ProcessOrders
CKTimer.Interval = 30000
CKTimer.AutoReset = True
Answer: A Explanation:
Use OnStart to specify the processing that occurs when the service receives a Start command. OnStart is the method in which you specify the behavior of the service. OnStart can take arguments as a way to pass data, but this usage is rare.
After configuration of the timer we must start it by raising the Enabled event. Reference:
.NET Framework Class Library, ServiceBase.OnStart Method [Visual Basic]
.NET Framework Class Library, Timer Members
.NET Framework Class Library, ServiceBase.OnCustomCommand Method [Visual Basic] Incorrect Answers
B, D: OnCustomCommand executes when the Service Control Manager (SCM) passes a custom command to
the service. The OnCustomCommand is not a good place to place define and configure a timer.
C: The Timer.AutoReset property indicates whether the Timer should raise the Elapsed event each time the specified Interval elapses or only after the first time it elapses. The default value is True, so there is no need to
set to true in this scenario. Furthermore, the timer will not start until the Enabled property is set to true.
QUESTION 2:
You develop an application named CKApp. This application needs to run on the same computer as a
Windows service named CKService.
You want to ensure that CKService starts from CKApp if CKService is not already running. Which code segment should you use?
A. Dim CKServiceController As New _ ServiceController(“CKService”)
If CKServiceController.Status = _ ServiceControllerStatus.Stopped Then CKServiceController.Start() End If
B. Dim CKServiceController As New _ ServiceController(“CKService”)CKServiceController.Start() C. Dim CKServiceController As New _
ServiceController() Dim CKArgs(1)As String CK Args(0)=”CKService”
If CKServiceController.Status = ServiceControllerStatus.Stopped
Then CKServiceController.Start(CKArgs) End If
D. Dim CKServiceController As New _
ServiceController() Dim CKArgs(1) As String CK Args(0)= “CKService” CKServiceController.Start(CKArgs)
Answer: A
Explanation: First we create a new instance of CKService. Then we check the current state of it with the
Status property. Finally we use the ServiceController start method to start it if it was stopped..
Note: A Service Controller object represents a Windows service and allows you to connect to a running or stopped service, manipulate it, or get information about it.
Reference:
.NET Framework Class Library, ServiceController Class
.NET Framework Class Library, ServiceController Members
.NET Framework Class Library, ServiceControllerStatus Enumeration [Visual Basic]
.NET Framework Class Library, ServiceController Constructor [Visual Basic]
Visual Basic and Visual C# Concepts, Creating ServiceController Component Instances
Incorrect Answers
B: The constructor is incorrect.
C, D: Here the ServiceController constructor is used with two parameters. The first parameter correctly references the existing server CKService. The second parameter, ‘CK’, specifies the computer that the service
runs on. CK has no special significance (we don’t know the name of the computer). Furthermore, we do not
have to specify the computer name if the service runs on the local computer.
QUESTION 3:
Your Microsoft SQL Server database contains a table named PassGuide Orders. PassGuide Orders is used
to store new purchase orders as they are entered into an order-entry application. To keep up with customer demand, the order fulfillment department wants to know at 15-minute intervals when new orders are entered.
You need to develop an application that reads PassGuide Orders every 15 minutes and sends all new
orders to the order fulfillment department. The application will run on computer that is used by several users who continuously log on and log off from the network to perform miscellaneous tasks.
Which type of .NET application should you use?
A. Windows Form
B. Windows service
C. XML Web service
D. .NET Remoting object
Answer: B
Explanation: A Windows service would still be running even though users logs on and off. Incorrect Answers
A: A Windows Form would be closed when a user logs off.
C: An XML Web service is not guaranteed to keep running if a user logs off.
D: You can use .NET Remoting to enable different applications to communicate with one another. However, a remoting object would be destroyed when a user logs off the system.
QUESTION 4:
You are creating a serviced component named ItemInventory. An online catalog application will use
ItemInventory to display the availability of products in inventory.
Additional serviced components written by other developers at PassGuide will continuously update the inventory data as orders are placed.
The ItemInventory class includes the following code segment:
Inherits ServicedComponent
‘ Method code goes here. End Class
ItemInventory is configured to require transactions. You want ItemInventory to respond to requests as quickly as possible, even if that means displaying inventory values that are not up to date with the most recent orders.
What should you do?
A. To the ItemInventory class, add the following attribute:
