You administer a SQL Server 2005 Reporting Services server. Your company publishes reports to a public Web site. Customers can view the reports without providing user credentials. You plan to upgrade the server to use SQL Server 2008 Reporting Services. You need to ensure that customers can continue to view the reports without providing user credentials.
What should you do?
A.
Enable Basic authentication.
B.
Enable Anonymous access on the IIS virtual directory.
C.
Use a custom authentication extension.
D.
Select Windows Authentication and add the Guest user account.
Explanation:
Tip: "without providing user credentials" = "custom authentication"Authentication
All users or automated processes that request access to Report Server must be authenticated before access is allowed. Reporting Services provides default authentication based on Windows integrated security and assumes trusted relationships where client and network resources are in the same domain or a trusted domain. You can change the authentication settings to narrow the range of accepted requests to specific security packages for Windows integrated security, use Basic authentication, or use a custom forms-based authentication extension that you provide. To change the authentication type to a method other than the default, you must deploy a custom authentication extension. Previous versions of SSRS relied on IIS to perform all types of authentication. Because SSRS 2008 no longer depends on IIS, there is a new authentication subsystem that supports this. The Windows authentication extension supports multiple authentication types so that you can precisely control which HTTP requests a report server will accept
