You are developing a data contract for a Windows Communication Foundation (WCF) service.
The data in the data contract must participate in round trips. Strict schema validity is not required.
You need to ensure that the contract is forward-compatible and allows new data members to be added to it.
Which interface should you implement in the data contract class?

• A. ICommunicationObject
• B. IExtensibleDataObject
• C. IExtension(Of T)
• D. IExtensibleObject(Of T)

A Windows Communication Foundation (WCF) service is self-hosted in a console application.
The service implements the ITimeService service interface in the TimeService class.
You need to configure the service endpoint for HTTP communication.
How should you define the service and endpoint tags?

• A. Define the service tag as follows.
  <service name="ITimeService">
  Define the endpoint tag as follows.
  < endpoint kind ="TimeService"
  address="http://localhost:8080/TimeService"
  binding="wsHttpBinding"
  contract="ITimeService"/>
• B. Define the service tag as follows.
  <service name="TimeService">
  Define the endpoint tag as follows.
  < endpoint kind="TimeService"
  address="http://localhost:8080/TimeService"
  binding="wsHttpBinding"
  contract="ITimeService"/>
• C. Define the service tag as follows.
  <service name="ITimeService">
  Define the endpoint tag as follows.
  < endpoint name="TimeService"
  ddress="http://localhost:8080/TimeService"
  binding="wsHttpBinding"
  contract="ITimeService"/>
• D. Define the service tag as follows.
  <service name="TimeService">
  Define the endpoint tag as follows.
  <endpoint address="http://localhost:8080/TimeService"
  binding="wsHttpBinding"
  contract="ITimeService"/>

A Windows Communication Foundation (WCF) service implements the following cortract.
<ServiceContract0>? Public Interface lHeloServic e <operationContractQ> <WebGet(UriTempbte: ="helloname={name}")s Function SayHello(Byval name As String) As nng End Interface The implementation is as follows Public Class HelloService Implements IHelloService
Public Function SayHello(ByVal name As String) As String - Implements lHelloServiceSayHello
Retumn "Hello "& name
End Function
End Cesst
The service is self-hosted, and the hosting code is as follows.
Dim stHost As WebServiceHo = CreateHost()
svcHo Open()
Consde ReadLine()
svcHoaClose()
You need to implement CreateHost so that the service has a single endpoint hosted
http:/Ilocalhost8000/HeloService.
Which code segment should you use?

• A. Dim svc Host As WebSennceHost = New WebServiceHost(GetType(HdloService))
  svc HotsAddServiceEndpoint(GdType(lHelloService),
  New WebHttpBinding(WebHttpSecurityModeNone),
  "http:/Ibc alhost 8000!HelloService")
  Return svc Host
• B. Dim baseAddress As Ur New Uri("http:/i1ocahost:8000r) Dim svcHo As WebServiceHost
  =
  New WebServiceHost(GetType(HelloService), baseAddress)
  svc Host.AddServiceEndpoint(GdType(lHelloService),?
  New Web Http Binding (WebHttpSec urityMode None),
  HelloService)
  Return svc Host
• C. Dim baseAddress As Ur = New Uri("http/I1ocahost 8OOOP Dim svcHo As
  WebServiceHost = New
  WebServiceHost(New HelloService0, baseAddress)
  svc HostAddServiceEndpoint(GdType(IHelIoService),
  New WebHttpBinding(WebHttpSecuntyMode None),
  "HelloService")
  Return svc Host
• D. Dim svc Host As WebServiceHost = New WebServiceHost(New HelloSennceO)
  svcHost.AddServiceEndpoint(GetType(IHelloService),
  New WebHttpBinding(WebHttpSecurityModeNone),
  Thttp://bc aihost: 8000/HelloSennce")
  Return svc Host

You are developing a Windows Communication Foundation (WCF) REST service to provide access to a library book catalog. The following code segment defines the service contract. (Line numbers are included for reference only.)

Library patrons want the ability to search the catalog by title.
You need to ensure that the GetBookByTitle method is exposed as a service method.
Which code segment should you insert at line 05?

• A. [WebGet(UriTemplate = "Book/{title}")]
• B. [WebGet(UriTemplate = "Book/{titleToSearch}")]
• C. [WebGet(UriTemplate = "{titleToSearch}"]
• D. [WebGet(UriTemplate = "BookByTitle/{title}")]

You are modifying a Windows Communication Foundation (WCF) service that issues security tokens. The service is accessible through the named pipe protocol. No endpoints are added in the service code. The configuration file for the service is as follows. (Line numbers are included for reference only.)

You need to ensure that new and existing client applications can access the service through HTTP and named pipes.
What should you do?

• A. Insert the following line at line 08. <add baseAddress="http://www.contoso.com" />
• B. Insert the following line at line 05.
  <endpoint address=http://www.contoso.com binding="basicHttpBinding" contract="Contoso.TokenService" />
• C. Insert the following line at line 08. <add baseAddress="net.tcp://www.contoso.com:8090" />
• D. Insert the following line at line 05. <endpoint address=http://www.contoso.com binding="wsHttpBinding" contract="Contoso.TokenService" />
