Microsoft TS: Microsoft .NET Framework 3.5 C Windows Communication Foundation Sample Questions:

Question 1

You are creating a client application by using Microsoft .NET Framework 3.5. The application will be accessible on the Internet.
You plan to use the wsHttpBinding binding by using HTTPS. The Windows Communication Foundation (WCF) service is hosted by a Windows service. You associate the HTTPS port of the WCF server with an X.509 certificate.
You need to ensure that the client application trusts and validates the certificate.
What should you do?

A. Subscribe to the ServerCertificateValidationCallback event of the System.Net.ServicePointManager class.
Write the validation code in the boolValidate(object sender, X509Certificate cert, X509Chain chain. System.Net.Security .SslPolicyErrors error) event handler on the server side.
B. Subscribe to the ServerCertificateValidationCallback event of the System.Net.ServicePointManager class.
Write the validation code in the boolValidate(object sender, X509Certificate cert, X509Chain chain. System.Net.Security.SslPolicyErrors error) event handler on the client side.
C. Derive a class from the System.IdentityModel.Selectors.X509CertificateValidator class.
Create an instance of the derived class on the server side.
Write the validation code in the public override void Validate(X509Certificate2 certificate) method.
D. Derive a class from the System.IdentityModel.Selectors.X509CertificateValidator class.
Create an instance of the derived class on the client side.
Write the validation code in the public override void Validate(X509Certificate2 certificate) method.

Question 2

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.)

When you browse to the base address of the service, you receive the following message: "Metadata publishing for this service is currently disabled."
You debug the code and discover that the ServiceMetadataBehavior behavior was previously nonexistent. You need to enable metadata publishing.
What should you do?

A. Insert the following code segment at line 11. smb.HttpGetEnabled=true;
B. Modify the code segment at line 03 in the following manner. Uri mexAddress=neUri("/service");
C. Insert the following code segment at line 19. smb.HttpGetEnabled=true;
D. Delete lines 15 and 16.

Question 3

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

Question 4

You are creating a distributed application by using Microsoft .NET Framework 3.5. You use Windows Communication Foundation (WCF) to create the application.
The distributed application contains client applications and a WCF service.
The client applications send e-mail address claims to the WCF service. The custom authorization manager of the service examines whether the claims are of the type "http://contoso.com/ClaimTypes/UserStatus".
You write the following code segment. (Line numbers are included for reference only.)

types that are expected by the custom authorization manager of the service. Which code segment should you insert at line 14?

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

Question 5
