You create a Windows Communication Foundation (WCF) service by using Microsoft .NET Framework 3.5. The WCF service accepts service requests from different partner applications. One of the partner applications occasionally receives faults. You need to identify why the service is generating faults. You must accomplish this goal without interrupting the service. What should you do?

• A. Run SvcTraceViewer.exe /register on the WCF server.
• B. Add the following code segment to the application configuration file.
  <system.diagnostics>
  <switches>
  <add name="WcfFaultTrace" value="Error" />
  </ switches>
  </system.diagnostics>
• C. Configure the Service Tracing options in the application configuration file. Analyze the
  trace results by using the SvcTraceViewer.exe program.
• D. Connect remotely to the WCF service by using a debugger. Place breakpoints in the
  exception handling code segment.

You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5.
You add the following code fragment to the app.config file for the service.

You need to enable personal identifiable information (PII) logging for the second trace source.
What should you do?

• A. Rename the second source listener name to Pii.
• B. Set the logKnownPii attribute to false for the first source in the code fragment.
• C. Set the logKnownPii attribute to true for the second source in the code fragment.
• D. Set the logKnownPii attribute to true for the first source in the code fragment.

You are creating a Windows Communication Foundation distributed application by using Microsoft .NET Framework 3.5. You write the following code segment to implement the service contract. (Line numbers are included for reference only.)

You need to ensure that the client applications of only those users who belong to the Administrators group can access the RemoveOrder method.
Which code segment should you insert at line 05?

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

You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. The service will be hosted on a Web server. You add the following code fragment to the .svc file.
<% @ServiceHost Factory="ExamServiceFactory" Service="ExamService" %>
You need to create the instances of the services by using the custom ExamServiceFactory
class.
Which code segment should you use?

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

You create a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. You write the following code segment.

You need to ensure that concurrent calls are allowed on the service instance.
Which code segment should you insert at line 06?

• A. <ServiceBehavior(ConcurrencyMode:=ConcurrencyMode.Multiple, _ ReleaseServicelnstanceOnTransactionComplete:=False)> _
• B. <ServiceBehavior(ConcurrencyMode:=ConcurrencyMode.Reentrant, _ ReleaseServicelnstanceOnTransactionComplete:=True)> _
• C. <ServiceBehavior(ConcurrencyMode:=ConcurrencyMode.Multiple, _ ReleaseServicelnstanceOnTransactionComplete:=True)> _
• D. <ServiceBehavior(ConcurrencyMode:=ConcurrencyMode.Reentrant, _ ReleaseServicelnstanceOnTransactionComplete:=False)> _
