You create a Windows Communication Foundation service by using Microsoft .NET
Framework 3.5. You set up tracing for the service.
The tracing fails because of an error in the service configuration. You need to identify the cause of the error.
What should you do?

• A.Examine the application event log.
• B.Examine the system event log.
• C.Examine the security event log.
• D.Set the enableLogKnownPii attribute to true in the machine, config file.

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.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.
• 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 server side.
• C.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.
• D.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.

You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5.
You need to ensure that you can customize the behavior of the ClientRuntime class and the DispatchRuntime class. You must achieve this goal without altering the behavior of the service.
What should you do?

• A.Implement the IOperationBehavior interface to create an Operation behavior.
• B.Implement the IServiceBehavior interface to create a Service behavior.
• C.Implement the IEndpointBehavior interface to create an Endpoint behavior.
• D.Implement the IContractBehavior interface to create a Contract behavior.

You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. The service contains the following binding configuration in the configuration file. (Line numbers are included for reference only.)
01 <wsHttpBinding>
02 <binding name="ssl">
04 </binding>
05 </wsHttpBinding>
You need to ensure that the following requirements are met:
Which configuration setting should you insert at line 03?

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

Your company has a set of e-commerce services that were created by using Microsoft .NET Framework 3.5. The Windows Communication Foundation model was used to create the services.
The services include a catalog and a shopping cart that are deployed to the same physical server. The catalog is a stateless, single-instance service. The shopping cart is a reentrant, per-session service.
The catalog service contains the following code fragment.

The shopping cart service contains the following code fragment.

During peak hours, the number of simultaneous catalog requests increase. This prevents customers from updating their shopping carts. You need to ensure that the customers can update their shopping carts even during peak catalog request traffic.
Which set of code fragments should you use to replace the existing code fragments?

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