Question 1

You are using tracing to diagnose run-time issues when you look at the traces for the service in Svc Trace viewer exe, you see what is shown in the exhibit (Click the Exhibit button)

The exception trace is selected in Svc Trace reviewer exe.
You need to interpret the trace results to determine where the error occurred and what to do next.
What should you do?

A. This issue occurred in the Service Host during Service Host. Open. Compare the security settings for any endpoints that use an MSMQ transport to the security configuration of the MSMQ queue used by the endpoint B. This issue occurred in the ServiceHost during ServiceHost Open. Enable WMI by adding the following configuration to the system.serviceModel configuration section in the application configuration file <diagnostics wmiProviderEnabledetrue'!> Restart the application and inspect the endpoints visible through WMI C. This issue occurred at the Service Host when receiving a message Compare the security configurations on the client and server to make sure that they are compatible D. This issue occurred at the ServiceHost when accepting an initial set of messages from MSMQ.Log all messages sent between the clients and sever.

Correct Answer: A

Question 2

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

Correct Answer: A

Question 3

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?

A. HostInstance.Credentials.ServiceCertificate.SetCertificate( StoreLocation.LocalMachine, StoreName.AuthRoot, X509FindType.FindBySubjectName, "CN=TaxServiceKey"); B. HostInstance.Credentials.ServiceCertificate.SetCertificate( StoreLocation.LocalMachine, StoreName.Root, X509FindType.FindBySubjectDistinguishedName, "CN=TaxServiceKey"); C. HostInstance.Credentials.ServiceCertificate.SetCertificate( StoreLocation.LocalMachine, StoreName.My, X509FindType.FindBySubjectDistinguishedName, "CN=TaxServiceKey"); D. HostInstance.Credentials.ServiceCertificate.SetCertificate( StoreLocation.LocalMachine, StoreName.My, X509FindType.FindBySubjectName, "CN=TaxServiceKey");

Correct Answer: B

A. Override the OnStart method and create and open a new ServiceHost.
Override the OnStop method and close the ServiceHost. B. Create a public method named Main.
Create a new ServiceHost in the Main method.
Override the OnShutdown method and close the ServiceHost. C. Override the OnPowerEvent method and open a new ServiceHost.

Override the OnStop method and close the ServiceHost.

Correct Answer: A

Question 5

You develop a Windows Communication Foundation (WCF) service. You enable all performance counters and run multiple calls to the service.

Correct Answer: C

Question 6

Your Windows Communication Foundation (WCF) client application uses HTTP to communicate with the service.
You need to enable message logging and include all security information such as tokens and nonces in logged messages.
What should you do?

A. In the application configuration file, add the logKnownPii attribute to the message
logging diagnostics source and set the value of the attribute to true.
Generate the ContosoService class using the Add Service Reference wizard. Add a
reference to System.ServiceModel.Routing.dll.
Add the following code segment.
ContosoService client = new ContosoService();
SoapProcessingBehavior behavior = new SoapProcessingBehavior();
behavior.ProcessMessages = true;
client.Endpoint.Behaviors.Add(behavior); B. In the application configuration file, add the following XML segment to the
system.serviceModel configuration section group.
<diagnostics>
<messageLogging logMessagesAtTransportLevel="true"
logEntireMessage="true" />
</diagnostics> C. In the machine configuration file, add the following XML segment to the
system.serviceModel configuration section.
<machineSettings enableLoggingKnownPii="true" />
In the application configuration file, add the logKnownPii attribute to the message logging
diagnostics source and set the value of the attribute to true. In the application configuration
file, add the following XML segment to the system.serviceModel configuration section
group.
<diagnostics>
<messageLogging logMessagesAtTransportLevel="true"/>
</diagnostics> D. In the machine configuration file, add the following XML segment to the
system.serviceModel configuration section.
<machineSettings enableLoggingKnownPii="true" />
Generate the ContosoService class using the Add Service Reference wizard.

Correct Answer: C

Question 8

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

Correct Answer: A

Question 9

You are developing a client application that consumes a Windows Communication Foundation (WCF) service.
You use the svcutil.exe utility to create a proxy for the service.
You use the svcutil.exe switches that generate asynchronous calls. GetFlight is a service operation that takes no parameters and returns a string. The GetFlightCallback method must be called when the service operation returns.
You create an instance of the client proxy with the following code.
var client = new TravelServiceClient();
You need to ensure that a callback is received when the GetFlight operation is called asynchronously.
Which code segment should you use?

A. client.BeginGetFlight(GetFlightCallback, null); client.GetFlight(); B. client.GetFlight(); client.BeginGetFlight(GetFlightCallback, null); C. IAsyncResult asyncResult = client.BeginGetFlight( GetFlightCallback, client); client.EndGetFlight(asyncResult); D. client.GetFlightCompleted += new EventHandler<GetFlightCompletedEventArgs>( GetFlightCallback); client.GetFlightAsync();

Correct Answer: D
