You have an existing Windows Communication Foundation (WCF) service.
You need to ensure that other services are notified when the service is started.
What should you do?

• A.Add a service behavior with the following element.
  <serviceDiscovery>
  <announcementEndpoints>
  <endpoint kind="udpAnnouncementEndpoint" />
  </announcementEndpoints>
  </serviceDiscovery>
• B.Add a service behavior with the following element.
  <serviceDiscovery>
  <announcementEndpoints>
  <endpoint kind="udpDiscoveryEndpoint" />
  </announcementEndpoints>
  </serviceDiscovery>
• C.Add the following standard endpoint to the service.
  <endpoint name="udpAnnouncementEndpoint"
  kind="udpDiscoveryEndpoint" />
• D.Add the following standard endpoint to the service.
  <endpoint name="udpDiscoveryEndpoint"
  kind="udpAnnouncementEndpoint" />

You are creating a Windows Communication Foundation (WCF) service.
You have the following requirements:
Messages must be sent over TCP.
The service must support transactions.
Messages must be encoded using a binary encoding.
Messages must be secured using Windows stream-based security.
You need to implement a custom binding for the service.
In which order should the binding stack be configured?

• A.transactionFlow binaryMessageEncoding windowsStreamSecurity tcpTransport
• B.tcpTransport windowsStreamSecurity transactionFlow binaryMessageEncoding
• C.binaryMessageEncoding transactionFlow tcpTransport windowsStreamSecurity
• D.windowsStreamSecurity tcpTransport binaryMessageEncoding transactionFlow

You develop a Windows Communication Foundation (WCF) service to generate reports. Client applications call the service to initiate report generation but do not wait for the reports to be generated. The service does not provide any status to the client applications.
The service class is defined as follows. (Line numbers are included for reference only.)
01 <ServiceContract()> 02 Public Class ReportGeneratorService 03 04 Private Function GenerateReports( ByVal clientID As Integer) As Integer 05 & 06 Return 0 07 End Function 08 09 End Class
You need to ensure that client applications can initiate reports without waiting for status.
Which two actions should you perform (Each correct answer presents part of the solution. Choose two.)

• A.Insert the following code at line 03. <OperationContract(IsOneWay:=True)>
• B.Insert the following code at line 03. <OperationContract(AsyncPattern:=False)>
• C.Remove line 06. At line 04, change the type of GenerateReports method to Sub. Remove the code As Integer from the method definition.
• D.At line 04, change the GenerateReports method from Private to Public.

A Windows Communication Foundation (WCF) service interacts with the database of a workflow engine. Data access authorization is managed by the database, which raises security exceptions if a user is unauthorized to access it.
You need to ensure that the application transmits the exceptions raised by the database to the client that is calling the service.
Which behavior should you configure and apply to the service?

• A.workflowUnhandledException
• B.serviceSecurityAudit
• C.routing
• D.serviceDebug

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());
