You are maintaining a Windows Communication Foundation (WCF) service that uses a custom username password class
to authenticate clients with. 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 same 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 hosting a Windows Communication Foundation (WCF) service under Microsoft Interent Information Services (IIS) 7.0.
You have set up a web site in IIS Manager. The physical path is c:\wwwroot\Calendar.
There is a Calendar.svc file in the c:\wwwroot\Calendar folder. It contains the following directive:

<% @ServiceHost Language=”C#” Debug=”true” Service=”Calendar.Calendar” CodeBehind=”CalendarSvc.cs” %>

The CalendarSvc.cs file contains the source for the Calendar class in the Calendar namespace.
You compile this code into the Calendar.dll file. You need to deploy your service to the web site. What should you do?

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)

01 <configuration>
02 <system.serviceModel>
03 <services>
04 <service name=”Contoso.TokenService”>
05 …
06 <host>
07 <baseAddress>
08 …
09 <add baseAddress=”net.pipe://www.contoso.com/tokenpipe” />
10 <baseAddress>
11 </host>
12 </service>
13 </services>
14 </system.serviceModel>
15 </configuration>

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

You are adding a Windows Communication Foundation (WCF) service to an existing application.
The application is configured as follows. (Line numbers are included for reference only)

01 <configuration>
02 <system.serviceModel>
03 <services>
04 <service name=”Contoso.Sales.Stock.Service”
05 behaviorConfiguration=”MetadataBehavior”>
06 <host>
07 <baseAddresses>
08 <add baseAddress=”http://contosso.com:8080/StockService” />
09 </baseAddresses>
10 </host>
11 </service>
12 </services>
13 <behaviors>
14 <serviceBehaviors>
15 <behavior name=”MetadataBehavior”>
16 </behavior>
17 </serviceBehaviors>
18 </behaviors>
19 …

You need to configure the service to publish the service metadata.
Which two actions should you perform? (Each answer presents part of the solution. Choose two.)

You are using tracing to diagnose run-time issues.When you look at the traces for the service in SvcTraceViewer.exe,
you see what is shown in the exhibit:

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

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 Windows Communication Foundation (WCF) service only accepts messages that are signed and encrypted.
A client application is not receiving expected responses from the service.
You need to enable logging to verify that the messages from the client are signed and encrypted.
You also need to see what each message looks like before the message body is deserialized into a NET object. What should you do?

A Windows Communication Foundation (WCF) service is required to log all authorization attempts to the Windows Event Log.
You need to configure a behavior and apply it to the service to support this requirement. Which behavior should you configure and apply?

A Windows Communication Foundation (WCF) service uses a list of application-defined roles for operations.
These roles are stored in a database. You need to authorize calls against the list of roles retrieved from the database.
Which service behavior should you use to authorize the calls?

You are creating a Windows Communication Foundation (WCF) service that accepts claims-based tokens.
You need to ensure that the service can use claims from trading partners even though there are variations on naming for the same elements.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)
