A Windows Communication Foundation (WCF) service listens for messages at net
tcpilwwwcontoso.comMMyService.
It has a logical address at http/Iwwwcontosocorn)MyService
The configuration for the WCF client is as follows
<endpoint addressrhTttpllwwwcontosocom/MyService"
bindinge"netTc pBinding"
bindingConfiguraton-NetTc pBinding_lMyService
contract="ServiceReference 1. IMyServce'
name='NetTcpBinding_lllyService"/>v
The generated configuration does not provide enough information for the client to communicate with the server.
You need to update the client so that it can communicate with the server what should you do

• A.After instantiating the client and before invoking any service operation, add this line of code. client. Endpoint BehaviorsAdd( new Client ViaBehavior( new Uhcnet.tc pifwww.contoso. comiIMyService)))
• B.In the client configuration. Change the value of the address attribute to nettcp:/Iwwwcontosocom/MyService
• C.In the client configuration, change the value of the address attribute to net.tcp:Ilwwwcontosocom/MyServicellisten=http:/Iwwwcontosocom/MyService.
• D.After instantiating the client and before invoking any service operation, add this line of code client Endpoint BehaviorsAdd( new EndpointDiscoveryBehawior0{ Enabled true });

A Windows Communication Foundation (WCF) service implements the following contract.
[ServiceContract| public interface IHelloService { [OperationContract]
[VVebGet(UriTemplate =
"hello?namee{name}")] string SayHello(string name);
}
The implementation is as follows.
public class HelloService: IHelloService { public string SayHello(string name)
{ return "Hello ".+ name;
}
}
The senvice is self-hosted, and the hosting code is as follows.
WebServiceHost svcHost = CreateHoseO;
svcHost.OpenO;
Console. ReadLineO;
SrvHost.CloseO;
You need to implement CreateHost so that the senvice has a single endpoint hosted at
http://localhost:8000/HelloService which code segment should you use?

• A.WebServiceHost svcHost = new Web Service Host(new HelloServiceO); svcHost
  AddServiceEndpoint(typeof(lHelloService),
  new WebHttpBinding(WebHttpSecurityMode. None),
  "http://Iocalhost: 8000/HelloService");
  return svcHost
• B.Ur baseAddress new Uri('http //Iocalhost 8000/");
  WebServiceHost svc Host =
  new WebServiceHost(new HelloService0, baseAddress),
  svc Host.AddServiceEndpoint(typeof(IHelloService),
  new WebHttpBinding(WebHttpSec urityMode None),
  "HelloService");
  retumn svc Host;
• C.WebServiceHost svcHost new WebServiceHost(typeof(HelloService));
  svcHost.AddServiceEndpoint(typeof(lHelloService),
  new WebHttpBinding(WebHttpSecurityMode None),
  "http://localhost:8000/HelloService");
  return svcHost;
• D.Ur baseAddress = new Urit'http:I/localhost:800O1");r
  WebServiceHost svc Host new WebServiceHost(typeof(HelloService), baseAddress);
  svcHostAddServiceEndpoint(typeof(lHelloService),
  new WebHttpBinding(WebHttpSecurityMode. None),
  "HelloService"); return svc Host;

You are developing a Windows Communication Foundation (WCF) service named CalculatorService, which implements the ICalculatorService contract. The service is configured to be discoverable through UDP. CalculatorService contains multiple endpoints. One of the endpoints is configured with the following behavior.

You need to log all the endpoint metadata information that is added by the service host. Which code segment should you use?

• A.Option C
• B.Option D
• C.Option A
• D.Option B

You are developing a Windows Communication Foundation (WCF) service that is used to
check the status of orders placed by customers. The following code segment is part of your service. (Line numbers are included for reference only.)

You need to ensure that the service always listens at net.pipe://SupplyChainServer/Pipe. What should you do?

• A.Option C
• B.Option D
• C.Option A
• D.Option B

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.
What should you do?

• A.Change line 03 as follows. typeof(l RequestReplyRouter),
• B.Change line 10 as follows. typeof(lRequestReplyRouter)
• C.Change line 10 as follows. typeof(lDuplexSessionRouter)
• D.Change line 03 as follows. typeof(lDuplexSessionRouter),
