NO.1 You create a Windows Workflow Foundation application by using Microsoft .NET Framework 3.5.
A Windows Forms application functions as the workflow host by using the
DefaultWorkflowSchedulerService.
You create a WorkflowRuntime instance in the Load event of the forms. You also subscribe to the
WorkflowCompleted event.
You need to ensure that the application displays the message in the Label control named lblStatus when
the WorkflowCompleted event is raised.
Which code segment should you use?
A. Private Sub UpdateInstances(ByVal id As Guid)
If Me.InvokeRequired Then
lblStatus.Text = id.ToString & " completed"
End If
End Sub
B. Private Sub UpdateInstances(ByVal id As Guid)
If (Not Me.InvokeRequired) Then
lblStatus.Text = id.ToString & " completed"
End If
End Sub
C. Private Delegate Sub UpdateInstancesDelegate(ByVal id As Guid)
Private Sub UpdateInstances(ByVal id As Guid)
If Me.InvokeRequired Then
Me.Invoke(New _
UpdateInstancesDelegate(AddressOf UpdateInstances), _
New Object() {id})
Else
lblStatus.Text = id.ToString & " completed"
End If
End Sub
D. Private Delegate Sub UpdateInstancesDelegate(ByVal id As Guid)
Private Sub UpdateInstances(ByVal id As Guid)
If Not Me.InvokeRequired Then
Me.Invoke(New _
UpdateInstancesDelegate(AddressOf UpdateInstances), _
New Object() {id})
Else
lblStatus.Text = id.ToString & " completed"
End If
End Sub

NO.3 You use a built-in tracking service to track specific workflow parameters.
You need to check whether the workflow parameters have been stored in the tracking database.
What should you do? (Each correct answer presents part of a solution. Choose two.)
A. Display the contents of the WorkflowInstance table of the tracking database.
B. Include the SqlTrackingQuery class in a code segment to retrieve tracked workflows and
SqlTrackingWorkflowInstance class to inspect them.
C. Use the ActivityTrackingLocation class to determine if the value has been set to a database.
D. Display the contents of the TrackingDataItem table of the tracking database.

NO.4 You create a Windows Workflow Foundation application by using Microsoft .NET Framework 3.5.
The application uses a markup-only workflow.
The workflow will also require the use of a code-beside file.
The following code fragment is implemented in XAML.
<SequentialWorkflowActivityx:Class="ProcessNewCustomer" Name="ProcessCustomer" xmlns=
"http://schemas.microsoft.com/winfx/2006/xaml/workflow"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
</SequentialWorkflowActivity>
You need to create a class declaration to implement the custom code.
Which code segment should you use?
A. Partial Public Class ProcessNewCustomer
Inherits SequentialWorkflowActivity
' Class implementation code appears here.
End Class
B. Public Class ProcessNewCustomer
Inherits SequentialWorkflowActivity
' Class implementation code appears here.
End Class
C. Public Class ProcessNewCustomerCode
Inherits ProcessNewCustomer
' Class implementation code appears here.
End Class
D. Partial Public Class ProcessCustomer
Inherits SequentialWorkflowActivity
' Class implementation code appears here.
End Class

NO.5 You create a Windows Workflow Foundation application by using Microsoft .NET Framework 3.5.
You plan to call a method in the workflow host to send messages.
You write the following code segment.
Public Interface IOrderCommunication
Sub UpdateOrder(ByVal orderId As String)
End Interface
You need to decorate the interface.
Which line of code should you use?
A. <LocalizableAttribute(true)>
B. <ExternalDataExchangeAttribute>
C. <CorrelationParameterAttribute("orderId")>
D. <ActivityCodeGeneratorAttribute("orderId")>
Answer: B

NO.6 You create an application in which users design simple sequential workflows. The designs are stored
as XOML in a SQL database. You need to start one of these sequential workflows from within your own
workflow.
What should you do?
A. Include a custom activity with a code segment that includes an invocation to the CreateWorkflow
method of the WorkflowRuntime class and then starts the workflow. The signature of the CreateWorkflow
method invoked uses only the workflowType parameter.
B. Include a custom activity with a code segment that includes an invocation to the CreateWorkflow
method of WorkflowRuntime class and then starts the workflow. The signature of the CreateWorkflow
method invoked uses only the XmlReader and workflowDefinitionReader parameters.
C. Include a custom activity with a code segment that includes an invocation to the CreateWorkflow
method of the WorkflowRuntime class and then starts the workflow. The signature of the CreateWorkflow
method invoked uses only the workflowType, Dictionary<string,Object> namedArgumentValues, and Guid
instanceId parameters.
D. Include and configure an InvokeWorkflow activity

NO.7 You create a Windows Workflow Foundation application by using Microsoft .NET Framework 3.5.
You plan to add a workflow to implement an order processing logic.
When the host initiates the order processing logic, it raises an event named StartProcessing.
You need to configure the local communication interface to enable the workflow to handle the event.
Which code segment should you use?
A. Public Interface IContract
Event StartProcessing As EventHandler(Of ExternalDataEventArgs)
End Interface
B. Public Class Contract
Inherits ExternalDataExchangeService
Private Event StartProcessing As EventHandler(Of _
ExternalDataEventArgs)
End Class
C. <ExternalDataExchange()> _
Public Interface IContract
Event StartProcessing As EventHandler(Of EventArgs)
End Interface
D. <ExternalDataExchange()> _
Public Interface IContract
Event StartProcessing As EventHandler(Of ExternalDataEventArgs)
End Interface

NO.8 You are writing a sequential console workflow that consists of a delay activity and a code activity, as
shown in the exhibit. (Click the Exhibit button for the sequential console workflow image.)
In the execution code of the second activity, you try to modify the workflow as follows:
Private Sub delayActivity_InitializeTimeoutDuration(ByVal sender As System.Object, ByVal e As
System.EventArgs)
Console.Title = "Modifiability of a Workflow"
Console.WriteLine("Wait ...")
End Sub
Private Sub codeActivity_ExecuteCode(ByVal sender As System.Object, ByVal e As System.EventArgs)
Dim delay As DelayActivity = CType(sender, DelayActivity)
Console.WriteLine(delay.Name)
Dim workflowChanges As New WorkflowChanges(Me)
Dim codeActivity As New CodeActivity()
codeActivity.Name = "codeActivity2"
AddHandler codeActivity.ExecuteCode, AddressOf Me.codeActivity2_ExecuteCode
workflowChanges.TransientWorkflow.Activities.Add(codeActivity)
Me.ApplyWorkflowChanges(workflowChanges)
End Sub
Private Sub codeActivity2_ExecuteCode(ByVal sender As System.Object, ByVal e As System.EventArgs)
Dim codeActivity As CodeActivity = CType(sender, CodeActivity)
Console.WriteLine(codeActivity.Name)
Console.ReadLine()
End Sub
You also have set the modifiability of the workflow to a code condition that is set to the following function:
Private Sub UpdateCondition(ByVal sender As System.Object, ByVal e As ConditionalEventArgs)
If (TimeSpan.Compare(Me.delayActivity.TimeoutDuration, New TimeSpan(0, 0, 5)) > 0) Then
e.Result = False
Else
e.Result = True
End If
End Sub
Which code segment should you use to handle the exception?
A. workflowChanges.TransientWorkflow.Activities.Add(codeActivity)
Try
Me.ApplyWorkflowChanges(workflowChanges)
Catch ex As ArgumentOutOfRangeException
Console.WriteLine(ex.GetType().ToString())
Console.ReadLine()
End Try
B. workflowChanges.TransientWorkflow.Activities.Add(codeActivity)
Try
Me.ApplyWorkflowChanges(workflowChanges)
Catch ex As InvalidProgramException
Console.WriteLine(ex.GetType().ToString())
Console.ReadLine()
End Try
C. workflowChanges.TransientWorkflow.Activities.Add(codeActivity)
Try
Me.ApplyWorkflowChanges(workflowChanges)
Catch ex As InvalidOperationException
Console.WriteLine(ex.GetType().ToString())
Console.ReadLine()
End Try
D. workflowChanges.TransientWorkflow.Activities.Add(codeActivity)
Try
Me.ApplyWorkflowChanges(workflowChanges)
Catch ex As OverflowException
Console.WriteLine(ex.GetType().ToString())
Console.ReadLine()
End Try
