You create a Windows Communication Foundation (WCF) service by using Microsoft .NET Framework 3.5. The WCF service contains two operations named ProcessSimpleOrder and ProcessComplexOrder.
You need to expose the ProcessSimpleOrder operation to all the client applications. You also need to expose the ProcessComplexOrder operation only to specific client applications.
Which code segment should you use?

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

You are creating a distributed application by using Microsoft .NET Framework 3.5.
You use Windows Communication Foundation (WCF) to create the application. The operations provided by the WCF server use the remote resources of other computers.
These methods use the credentials provided by the client applications. You need to ensure that the WCF server can impersonate the client applications to access the remote resources.
Which client application settings should you use?

• A. <windows allowedlmpersonationLevel="lmpersonation" allowNtlm="false"/>
• B. <windows allowedlmpersonationLevel="Delegation"/>
• C. <windows allowedlmpersonationl_evel="ldentification"/>
• D. <windows allowedlmpersonationl_evel="lmpersonation"/>

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

You create a Windows Communication Foundation service by using Microsoft .NET Framework 3.5.
You add the following code segment to a configuration file. (Line numbers are included for reference only)
01 <configuration> 02 <system.serviceModel>
04 </system.serviceModel>
05 </configuration
You need to enable the performance counters to monitor the ServiceModelOperation object of the service.
You also need to ensure that the performance counters are disabled for all other services.
What should you do?

• A. Add the following code fragment at line 03 in the machine.config file. <diagnosticsperformanceCounters="ServiceOnly" />
• B. Add the following code fragment at line 03 in the app.config file. <diagnosticsperformanceCounters="All" />
• C. Add the following code fragment at line 03 in the app.config file. <diagnosticsperfocmanceCounters="ServiceOnly" />
• D. Add the following code fragment at line 03 in the machine.config file. <diagnosticsperfocmanceCounters="All" />
