You design a Business Intelligence （BI） solution by using SQL Server 2008.  The solution includes a SQL Server 2008 Reporting Services （SSRS） infrastructure in a scale-out deployment. All reports use a SQL Server 2008 relational database as the data source. You implement row-level security. You need to ensure that all reports display only the expected data based on the user who is viewing the report. What should you do？（）

• A、 Store the credential of a user in the data source.
• B、 Configure the infrastructure to support Kerberos authentication.
• C、 Configure the infrastructure to support anonymous authentication by using a custom authentication extension.
• D、 Ensure that all report queries add a filter that uses the User.UserID value as a hidden parameter.
