An existing Windows application uses a Windows Communication Foundation (WCF) Web service that is available only to employees.
You have the following requirements:
Make the WCF Web service available to business partners.
Enable business partners to send a profile token.

• B. Use SOAP headers to pass the profile token to the service operations.
• C. Implement the WCF Web service as a REST service.
• D. Modify the WCF Web service operations to accept the profile token as an additional parameter.

You are designing a Windows Forms application. The application connects to a Microsoft SQL Server 2008 database.
You need to recommend an approach for retrieving and logging all informational messages and error messages reported by the database.
What should you recommend?

• A. Retrieve informational messages and error messages by creating a handler for the InfoMessage event.
• B. Retrieve informational messages and error messages in a SqlException object.
• C. Retrieve informational messages by creating a handler for the InfoMessage event. Retrieve error messages in a SqlException object.

You are designing a Windows Presentation Foundation (WPF) application that uses .NET Framework 4. The application uses a subset of the functionality provided by a third-party COM component that will be replaced later.
The application developers must have access to only the required subset of functionality.
You need to recommend a solution that meets the requirements.
Which two actions should you recommend? (Each correct answer presents part of the solution. Choose two.)

• A. Create an adapter assembly that exposes the entire functionality of the COM component.
• B. Create an adapter assembly that exposes the required subset of the COM component functionality.
• C. In the adapter assembly, use a standard interop reference.
• D. In the adapter assembly, use an embedded interop reference.
