Microsoft 070-513 Exam Syllabus Topics:

Microsoft TS: Windows Communication Foundation velopment with Microsoft .NET Framework 4 Sample Questions:

1. You develop a Window Communication Foundation (WCF) service. You have the following requirements: - Create a data contract to pass data between client applications and the service. - Create the data that is restricted and cannot pass between client applications and
the service. You need to implement the restricted data members. Which member access modifier should you use?

A) Public
B) Private
C) Static
D) Protected

2. You create a Windows Communication Foundation (WCF) sen/ice. It is deployed on Microsoft Internet Information Services (IIS) with an application pool running as Network Service. You enable WMI tracing before launching the service. Your IT support staff adds WMI data collection through ASP.NET WMI tracing.
You need to restrict the collection of WMI data to a privileged account.
What should you do in WMI Control in the Computer Management console?

A) Select the Root\ServiceModel namespace.
Remove Enable account permission for the Network Service account.
Add a custom user and grant that user Enable account permission.
B) Select the Root\aspnet namespace.
Remove Enable account permission for the Local System account.
Add a custom user and grant that user Enable account permission.
C) Select the Root\aspnet namespace.
Remove Enable account permission for the Network Service account.
Add a custom user and grant that user Enable account permission.
D) Select the Root\Security namespace.
Remove Enable account permission for the Local System account.

3. You need to modify a client application that consumes a Windows Communication Foundation (WCF) service.
The service metadata is no longer available.
You need to modify the previously generated proxy to include asynchronous calls to the service.
What should you do?

A) Create a class with the same name as the previously generated proxy and add the new asynchronous methods as partial methods. Add the new class to a namespace that is different from the original proxy.
B) Create a class with the same name as the previously generated proxy and add the new asynchronous methods. Add the new class to a namespace that is different from the original proxy.
C) Update the service reference with the Generate asynchronous operations option.
D) Create a partial class for the previously generated proxy and include the new asynchronous methods.

4. A WCF service code is implemented as follows. (Line numbers are included for reference only)
01 [ServiceContract]
02 [ServiceBehavior(lnstanceContextMode =
03 lnstanceContextModeSingle)]
04 public class CalculatorService
05 {
06 [OperationContract]
07 public double Calculate(double op1, string op. double op2)
08 {
24 }
25 }
You need to increase the rate by which clients get the required response from the service.
What e two possible ways to achieve this goal? (Each correct answer presents a complete sokiion
Choose two.)

A) Require the clients use threads, the Parallel Task Library, or other mechanism to issue service calls in parallel.
B) Change the service behavior to the following.
[ServiceBehavior(
lnstanceContextMode = lnstanceContextModeSingle,
ConcirrencyMode = ConcurrencyMode. Multide)]c
C) Change the service behavior to the following.
[ServiceBehavior(lnstanceContextMode = lnstanceContextMode.PerCall)]
D) Require the clients to use async operations when calling the senvice.

5. You are developing a client application that uses the following code to consume a Windows
Communication Foundation (WCF) service. (Line numbers are included for reference only.)
01 Dim myBinding As BasicHttpBinding =
New BasicHttpBinding()
02 Dim myEndpointAddress As EndpointAddress =
New EndpointAddress(
"http://contoso.com/TaxService.svc")
04 Dim client As ITaxService =
channelFactory.CreateChannel()
05 Dim data As String = client.GetData(1)
You need to consume the service.
Which code segment should you insert at line 03?

A) channelFactory =
New ChannelFactory(Of ITaxService)
("http://contoso.com/TaxService.svc")
B) Dim channelFactory =
New ChannelFactory(Of ITaxService)
(myBinding, myEndpointAddress)
C) Dim channelFactory =
New ChannelFactory(Of ITaxService)(myBinding)
D) Dim channelFactory =
New ChannelFactory(Of ITaxService)()
