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

If the existing operation contract is unable to process a request made to the service, a generic operation contract must attempt to process the request.
You need to create the generic operation contract.
Which code segment should you insert at line 07?

• A. <OperationContract(Action:="Default")> _ Sub ProcessOthers()
• B. <OperationContract(Action:="*")> _ Sub ProcessOthers()
• C. <OperationContract(Action:="*")> _
  Sub ProcessOthers(ByVal msg As Message)
• D. <OperationContract(Action:="Default")> _ Sub ProcessOthers(ByVal msg As Message)

You are creating a Windows Communication Foundation service by using Microsoft .NET
Framework 3.5.
The service will be hosted in a Windows Service environment. You need to create a Windows Service class that instantiates a service host.
Which code segment should you use?

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

You create a distributed application by using Microsoft .NET Framework 3.5. You use Windows Communication Foundation to create the application.
You pass the client credentials to the service that runs on two Web servers named IIS1 and IIS2. The service uses the credentials to query data from a remote Microsoft SQL Server 2005 database named DB1.
The client applications can retrieve data from the service when they connect to IIS1. When the client applications attempt to retrieve data from the service by connecting to IIS2, they receive the following error message:
Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
You need to ensure that both IIS1 and IIS2 can query data from DB1.
What should you do?

• A. Execute the following command on a domain controller. setspn -A http/iis2.example.com:80 DOMAIN\iis2$
• B. Change the SQL connection string on IIS2 from "Data Source=DBl; Initial Catalog=db;Integrated Security=True" to "Data Source=DBl;Initial Catalog=db;Integrated Security=SSPI".
• C. Configure DB1 for full delegation.
• D. Configure IIS2 for constrained delegation to DB1.

You create a Windows Communication Foundation (WCF) service by using Microsoft .NET Framework 3.5. You need to enable WCF tracing at runtime by using Windows Management Instrumentation (WMI). Which three tasks should you perform? (Each correct answer presents part of the solution. Choose three.)

• A. Set the wmiProviderEnabled attribute to true in the configuration file.
• B. Use WMI to set the AppDomainlnfo trace properties to true.
• C. Set up a message log listener in the configuration file. Set all trace properties to false.
• D. Set up a System. ServiceModel trace listener in the configuration file. Set all trace properties to false.
• E. Set the performanceCounters attribute to ServiceOnly in the configuration file.
