You create a stateless, thread-safe service by using Microsoft .NET Framework 3.5. You use the Windows Communication Foundation model to create the service. Load testing reveals that the service does not scale above 1,000 concurrent users.
You discover that each call to the service instantiates a new service instance. You also discover that these service instances are expensive to create. You need to ensure that 5,000 concurrent users can access the service.
Which code segment should you use?

• A.[ServiceBehavior( lnstanceContextMode=lnstanceContextMode.PerCall ConcurrencyMode=ConcurrencyMode.Reentrant)]
• B.[ServiceBehavior( lnstanceContextMode=lnstanceContextMode.PerCall ConcurrencyMode=ConcurrencyMode.Multiple)]
• C.[ServiceBehavior( lnstanceContextMode=lnstanceContextMode. Single, ConcurrencyMode=ConcurrencyMode.Reentrant)]
• D.[ServiceBehavior( lnstanceContextMode=lnstanceContextMode.Single, ConcurrencyMode=ConcurrencyMode.Multiple)]

You are creating a client application by using Microsoft .NET Framework 3.5. You use Windows Communication Foundation (WCF) to create the application.
The client application uses a Personal Information Card to provide authentication information to the WCF server. You write the following code fragment. (Line numbers are included for reference only.)

You need to ensure that one of the claims in the Personal Information Card contains an e-mail address.
Which code fragment should you insert at line 05?

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

What actions should you take to inspect messages on server? (choose 3)

• A.Insert behavior before ICommonObject.Open
• B.Implemement IEndpointBehavior
• C.Implement IDispatchMessageInspector
• D.Implement IClientMessageInspector
• E.Implement IOperationBehavior
• F.Insert behavior before IClientObject.Open

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

You need to set the ServiceContract attribute for the transaction behavior of the service. Which code segment should you insert at line 01?

• A.<ServiceContract(SessionMode:=SessionMode.Allowed, _ ProtectionLevel:=ProtectionLevel.EncryptAndSign)> _
• B.<ServiceContract(SessionMode:=SessionMode.Allowed)> _
• C.<ServiceContract(SessionMode:=SessionMode.Required)> _
• D.<ServiceContract(SessionMode:=SessionMode.NotAllowed, _ ProtectionLevel:=ProtectionLevel.EncryptAndSign)> _

You create a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. The metadata for the service is available at http://localhost:8080/MyService/mex.
The svcutil.exe tool generates the following two files from the metadata:
You need to ensure that the configuration file is merged with an existing app.config file.
Which command should you use?

• A.Svcutil http: //localhost:8080/MyService/mex /out:Proxy.cs /mergeConfig
• B.Svcutil http: //localhost:8080/MyService/mex /out:Proxy.cs /config:app.config
• C.Svcutil http: //localhost:8080/MyService/mex /out:Proxy.cs /config:app.config /mergeconfig
• D.Svcutil http: //localhost:8080/MyService/mex /out:Proxy.cs /config:app.config /noconfig
