A Windows Communication Foundation (WCF) service implements a contract with one-way and requestreply operations.
The service is exposed over a TCP transport.
Clients use a router to communicate with the service. The router is implemented as follows. (Line numbers are included for reference only.)
01 ServiceHost host = new ServiceHost(typeof(RoutingService));
02 host AddServiceEndpoint(
03 typeof(lSimplexDatagramRouter),
04 new NetTcpBinding0, "net.tcp:/flocalhostlRouter"
05);
06 List <ServiceEndpoints lep new List <ServiceEndpoint>0;t
07 lep.Add(
08 new ServiceEndpoint(
09 ContractDescription.GetContract(
10 typeof(lSimplexDatagramRouter)
11),
12 new NetTcpBinding0,
13 new EndpointAddress|'nettcp://localhost: 8080/Logger")
14)
15);
16 RoutingConfiguration rc new RoutingConfigurationO;
17 FilterTable.Add(new MatchAilMessageFilterO, lep);
18 host. Description. Behaviors. Add(new RoutingBehavior(rc));
Request-reply operations are failing.
You need to ensure that the router can handle one-way and request-reply operations.

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 BasicHttpBinding myBinding = new BasicHttpBinding(); 02 EndpointAddress myEndpointAddress = new EndpointAddress( "http://contoso.com/TaxService.svc");
04 ITaxService client = channelFactory.CreateChannel();
05 string data = client.GetData(1);
You need to consume the service.
Which code segment should you insert at line 03?

A Windows Communication Foundation (WCF) solution uses two services to manage a shopping cart. Service
A processes messages containing line items that total between $0 and $500. Service B processes messages containing line items that total more than $500.
All messages are of equal importance to the business logic.
You need to route incoming messages to the appropriate services by using WCF routing.
Which two message filters should you add to the router? (Each correct answer presents part of the solution. Choose two.)

A Windows Communication Foundation (WCF) application exposes a service as a SOAP endpoint for consumption by cross-platform clients. During integration testing, you find that one of the clients is not generating the correct messages to the WCF application.
In order to debug the issue and fix the communication, you need to configure the service to log messages received from the client.

You are maintaining a Windows Communication Foundation (WCF) service that uses a custom UserNamePassword class to authenticate clients. The service certificate is hosted in the deployment server store for trusted root certificate authorities and has a Subject value of TaxServiceKey. Other service certificates hosted on the server also use TaxServiceKey as a Subject value.
You need to ensure that the service identifies itself with a certificate whose subject name and distinguished names are TaxServiceKey.
Which code segment should you use?

You are modifying a Windows Communication Foundation (WCF) service that allows customers to update financial data. The service currently requires a transaction from the client application and is working correctly. The service contract is defined as follows. (Line numbers are included for reference only.)
The service must be modified so that client applications do not need to initiate a transaction when calling the operation. The service must use the client application's transaction if one is available. Otherwise it must use its own transaction.
You need to ensure that the service operation is always executed within a transaction.
