NO.1 You create a Windows Workflow Foundation application by using Microsoft .NET Framework 3.5. The
application uses a sequential workflow as shown in the following exhibit. (Click the Exhibit button for the
sequential workflow image.)
The workflow implements an if condition as shown in the following exhibit. (Click the Exhibit button for the
if condition image.)
A new business policy requires the application to check if the amount is less than 15,000 instead of the
current default.
You write the following code segment in the host application. (Line numbers are included for reference
only.)
01 Dim newAmount As Int32 = 15000
02 Dim workflowchanges As _
03 New WorkflowChanges(instance.GetWorkflowDefinition())
04 Dim transient As CompositeActivity = _
05 workflowchanges.TransientWorkflow
06 Dim ruleDefinitions As RuleDefinitions = CType( _
07 transient.GetValue(ruleDefinitions. _
08 RuleDefinitionsProperty), RuleDefinitions)
09 Dim conditions As RuleConditionCollection = _
10 ruleDefinitions.Conditions
11
12 TryCast(condition1.Expression, _
13 CodeBinaryOperatorExpression).Right = _

NO.5 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.6 You create a Windows Workflow Foundation application by using Microsoft .NET Framework 3.5. You
use the state machine workflow in the application.
You plan to implement a mechanism that allows a host application to query a state machine workflow
instance that is currently executing.
You write the following code segment. (Line numbers are included for reference only.)
01 Dim runtime As New WorkflowRuntime()
02 Dim instance As WorkflowInstance = _
03 runtime.CreateWorkflow(GetType(Workflow1))
04 instance.Start()
05
You need to identify the current state of the workflow.
Which code segment should you insert at line 05?
A. Dim currentstate As String = instance.GetWorkflowDefinition().ToString
B. Dim currentstate As String = _
instance.GetWorkflowDefinition().ExecutionStatus.ToString
C. Dim smwi As New StateMachineWorkflowInstance(runtime, _
instance.InstanceId)
Dim currentstate As String = smwi.StateHistory(0)
D. Dim smwi As New StateMachineWorkflowInstance(runtime, _
instance.InstanceId)
Dim currentstate As String = smwi.CurrentStateName
Answer: D

NO.7 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.
Dim amount As Integer = 10
Dim runtime As New WorkflowRuntime()
Dim instance As WorkflowInstance = _
runtime.CreateWorkflow(GetType(DynamicUpdateWorkflow))
instance.Start()
Dim smwi As 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 Then
smwi.SetState("HighValueState")
Else
smwi.SetState("LowValueState")
End If
B. If amount >= 1000 Then
smwi.StateMachineWorkflow.SetValue _
(DynamicUpdateWorkflow.StatusProperty, "HighValueState")
Else
smwi.StateMachineWorkflow.SetValue _
(DynamicUpdateWorkflow.StatusProperty, "LowValueState")
End If
C. If amount >= 1000 Then
instance.GetWorkflowDefinition().SetValue
(DynamicUpdateWorkflow.StatusProperty, "HighValueState")
Else
instance.GetWorkflowDefinition().SetValue
(DynamicUpdateWorkflow.StatusProperty, "LowValueState")
End If
D. If amount >= 1000 Then
Dim high As StateActivity = _
CType(smwi.StateMachineWorkflow.Activities("HighValueState"), _
StateActivity)
smwi.SetState(high)
Else
Dim low As StateActivity = _
CType(smwi.StateMachineWorkflow.Activities("LowValueState"), _
StateActivity)
smwi.SetState(low)
End If

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
