Microsoft TS: Windows Communication Foundation velopment with Microsoft .NET Framework 4 : 70-513 Exam

You are developing a Windows Communication Foundation (WCF) service that reads messages from a public non-transactional MSMQ queue.
You need to configure the service to read messages from the failed-delivery queue.
Which URI should you specify in the endpoint configuration settings of the service?

• A. net.msmq://localhost/system$;DeadLetter
• B. net.msmq://localhost/msmq$;DeadLetter
• C. net.msmq://localhost/msmq$;FailedMessages
• D. net.msmq://localhost/system$;DeadXact

You are creating a Windows Communication Foundation (WCF) service that uses claims-based authorization. The following code retrieves the correct claim set.
var claims = ServiceSecurityContext.Current.
AuthorizationContext.ClaimSets[0];
You need to validate that the requesting client application has included a valid DNS value in the claim.
Which code segment should you use to retrieve the claim for validation?

• A. claims.ContainsClairo(Claim.CreateDnsClaim(ClaimTypes.Dns));
• B. claims.FindClaims(ClaimTypes.Dns, Rights.PossessProperty) .FirstOrDefault();
• C. claims.FindClaims(ClaimTypes.Dns, Rights.Identity) .FirstOrDefault();
• D. claims.Equals(ClaimTypes.Dns);

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

You want to debug the Windows Communication Foundation (WCF) client and server interaction through message and application tracing.
You need to correlate traces generated on the client and the server.
Which XML segment should you add to the system. diagnostics configuration element in the client and server application configuration file?

• A. <sources> <source propagate Activitye'true" namee"System Service Model"
  switchValues'Warning, ActivityTracing'> <listeners
  <add namez"ServiceModelTraceListener" /> </listeners>
  </source> </sources>
• B. <sources> <source names" System ServiceModel. MessageLogging"
  switchValuee"Verbose"> <listeners>
  <add namez"ServiceModelTraceListener" /> <Listeners>
  </source> </sources>
• C. <sources>
  <source names"System. ServiceModel" switchValues'VerboseActivityTracing"> <listeners>
  <add namee"ServiceModelTraceListener" /> </listeners> </source>
  </sources>
• D. <sources>
  <source names"System. ServiceModeiMessageLogging" propagateActivitye'true" switch Values' Warning, ActivityTracing'5 <listeners> <add name="ServiceModelTraceListener" I> </listeners> </source> </sources>

You are developing an application to update a user s social status. You need to consume the service using Windows Communication Foundation (WCF).
The client configuration is as follows.
<system.serviceModel> <bindings> <webHttpBinding>
<binding name="SocialConfig">
<security mode="TransportCredentialOnly">
<transport clientCredentialType="Basic"
realm="Social API" />
</security>
</binding>
</webHttpBinding>
</bindings>
<client>
<endpoint address= " http:// contoso .com "
binding="webHttpBinding"
bindingConfiguration="SocialConfig"
contract="ISocialStatus"
name="SocialClient" />
</client>
</system.serviceModel>
The service contract is defined as follows.
<ServiceContract()>
Public Interface ISocialStatus
<OperationContract()>
<WebInvoke(UriTemplate:="/statuses/update.xmlstatus={text}")>
Sub UpdateStatus(ByVal text As String)
End Interface
Which code segment should you use to update the social status?

• A. Using factory As ChannelFactory(Of ISocialStatus) =
  New WebChannelFactory(Of ISocialStatus)(GetType(ISocialStatus))
  factory.Credentials.UserName.UserName = user.Name
  factory.Credentials.UserName.Password = user.Password
  Dim socialChannel As ISocialStatus = factory.CreateChannel()
  socialChannel.UpdateStatus(newStatus)
  End Using
• B. Using factory As WebChannelFactory(Of ISocialStatus) =
  New WebChannelFactory(Of ISocialStatus)(GetType(ISocialClient))
  factory.Credentials.Windows.ClientCredential.UserName =
  user.Name
  factory.Credentials.Windows.ClientCredential.SecurePassword.SetAt(
  0, user.Password)
  Dim socialChannel As ISocialStatus = factory.CreateChannel()
  socialChannel.UpdateStatus(newStatus)
  End Using
• C. Using factory As ChannelFactory(Of ISocialStatus) =
  New ChannelFactory(Of ISocialStatus)("POST")
  factory.Credentials.Windows.ClientCredential.UserName =
  user.Name
  factory.Credentials.Windows.ClientCredential.SecurePassword.SetAt(
  0, user.Password)
  Dim socialChannel As ISocialStatus = factory.CreateChannel()
  socialChannel.UpdateStatus(newStatus)
  End Using
• D. Using factory As WebChannelFactory(Of ISocialStatus) =
  New WebChannelFactory(Of ISocialStatus)("SocialClient")
  factory.Credentials.UserName.UserName = user.Name
  factory.Credentials.UserName.Password = user.Password
  Dim socialChannel As ISocialStatus = factory.CreateChannel()
  socialChannel.UpdateStatus(newStatus)
  End Using
