DRAG DROP
You are preparing to deploy a Windows Communication Foundation (WCF) service to a production environment.
The service must not be vulnerable to a man-in-the-middle attack. You need to configure the service to use X.509 certificate security.
Which four actions should you perform in sequence? (To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.)

You have a self-hosted Windows Communication Foundation (WCF) service.
You need to configure the service to provide an X.509 certificate during authentication
What should you use to configure the service?

• A. the SetCertificate method of the X5O9CertificateRecipientServiceCredential class
• B. the Certificate property of the X509CertificatelnitiatorServiceCredential class
• C. the SetCertificate method of the X509CertificatelnitiatorServiceCredential class
• D. the TrustedStoreLocation property of the X5O9CertificateRecipientServiceCredential class

You are creating a Windows Communication Foundation (WCF) service. The service endpoints change frequently.
On the service, you add a new ServiceDiscoveryBehavior to the Behaviors collection of the ServiceHost Description property.
You need to ensure that client applications can communicate with the service and discover changes to the service endpoints.
What should you do?

• A. Use the FindCriteria class and the UdpDiscoveryEndpoint class to set up the binding in the client application.
• B. Add a new AnnouncementClient to the Behaviors collection in the client application.
• C. Use the DiscoveryProxy class and the EndpointDiscoveryMetadata class to set up the binding in the client application.
• D. Add a new ServiceDiscoveryBehavior to the Behaviors collection in the client application.

A Windows Communication Foundation (WCF) client application is consuming an RSS syndication feed from a blog. You have a SyndicationFeed variable named feed. The application iterates through the items as follows. (Line numbers are included for reference only.)
01 foreach (SyndicationItem item in feed.Items)
02 {
03 }
You need to display the content type and body of every syndication item to the console.
Which two lines of code should you insert between lines 02 and 03?

• A. Console.WriteLine(item.Content.GetType()); Console.WriteLine(((TextSyndicationContent)item.Content).Text);
• B. Console.WriteLine(item.Content.Type); Console.WriteLine(((TextSyndicationContent)item.Content).Text);
• C. Console.WriteLine(item.Content.Type); Console.WriteLine(item.Content.ToString());
• D. Console.WriteLine(item.Content.GetType()); Console.WriteLine(item.Content.ToString());

You are using tracing to diagnose run-time issues when you look at the traces for the service in Svc Trace viewer exe, you see what is shown in the exhibit (Click the Exhibit button)

The exception trace is selected in Svc Trace reviewer exe.
You need to interpret the trace results to determine where the error occurred and what to do next.
What should you do?

• A. This issue occurred in the ServiceHost during ServiceHost Open. Enable WMI by adding the following configuration to the system.serviceModel configuration section in the application configuration file <diagnostics wmiProviderEnabledetrue'!> Restart the application and inspect the endpoints visible through WMI
• B. This issue occurred at the ServiceHost when accepting an initial set of messages from MSMQ.Log all messages sent between the clients and sever.
• C. This issue occurred in the Service Host during Service Host. Open. Compare the security settings for any endpoints that use an MSMQ transport to the security configuration of the MSMQ queue used by the endpoint
• D. This issue occurred at the Service Host when receiving a message Compare the security configurations on the client and server to make sure that they are compatible
