NO.1 Question
You create a Windows Workflow Foundation application by using Microsoft .NET Framework 3.5. The
application contains a state workflow.
You write the following code segment.
WorkflowRuntime runtime = new WorkflowRuntime();
WorkflowInstance instance = runtime.CreateWorkflow(
?typeof(DynamicUpdateWorkflow));
instance.Start();
StateMachineWorkflowInstance smwi =
?new StateMachineWorkflowInstance(runtime,
?instance.InstanceId);
A dependency property named Status is defined in this workflow.
The value of a variable named amount is used to set the state of the workflow.
You need to ensure that the host application changes the state of the workflow on the basis of the value of
the amount variable.
What are the two possible code segments that you can use to achieve this goal? (Each correct answer
presents a complete solution. Choose two.)
A. if (amount >= 1000)
?smwi.SetState("HighValueState");
else
?smwi.SetState("LowValueState");
B. if (amount >= 1000)
?smwi.StateMachineWorkflow.SetValue
?(DynamicUpdateWorkflow.StatusProperty,"HighValueState")
else
?smwi.StateMachineWorkflow.SetValue
?(DynamicUpdateWorkflow.StatusProperty, "LowValueState");
C. if (amount >= 1000)
?instance.GetWorkflowDefinition().SetValue
?(DynamicUpdateWorkflow.StatusProperty,"HighValueState");
else
?instance.GetWorkflowDefinition().SetValue
?(DynamicUpdateWorkflow.StatusProperty,"LowValueState");
D. if (amount >= 1000)
{
??StateActivity high = (StateActivity)
???smwi.StateMachineWorkflow.Activities["HighValueState"];
??smwi.SetState(high);
}
else
{
??StateActivity low = (StateActivity)
???smwi.StateMachineWorkflow.Activities["LowValueState"];
??smwi.SetState(low);
}

NO.3 Question
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 void UpdateInstances(Guid id) {
??if (this.InvokeRequired) {
????lblStatus.Text = id + " completed";
??}
}
B. private void UpdateInstances(Guid id) {
??if (!this.InvokeRequired) {
????lblStatus.Text = id + " completed";
??}
}
C. delegate void UpdateInstancesDelegate(Guid id);
private void UpdateInstances(Guid id) {
??if (this.InvokeRequired) {
????this.Invoke(
?????new UpdateInstancesDelegate(UpdateInstances),
?????new object[] { id });
??} else {
????lblStatus.Text = id + " completed";
??}
}
D. delegate void UpdateInstancesDelegate(Guid id);
private void UpdateInstances(Guid id) {
??if (!this.InvokeRequired) {
????this.Invoke(
?????new UpdateInstancesDelegate(UpdateInstances),
?????new object[] { id });
??} else {

NO.4 Question
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

NO.6 Question
You are creating a Windows Workflow Foundation custom activity by using Microsoft .NET Framework
3.5.
You need to ensure that the following requirements are met:
The custom activity communicates with a local service hosted in the workflow runtime.
The local service receives data from the custom activity.
What should you do?
A. Define a method for the local service. Use the custom activity to invoke the method and pass data as a
method parameter.
B. Define a new event for the custom activity. Use the local service to subscribe to the event and receive
the data in the event arguments.
C. Place the data in the UserData property of the custom activity. Use the local service to read the data
directly from the UserData property.
D. Create and configure a workflow queue when the custom activity initializes. Use the custom activity to
write data to the workflow queue. Use the local service to read data from the workflow queue when the
data arrives.
