Answer: B

Explanation:

To provide redundancy, we would need to create AD FS farms with at least two servers. This can be used to allow internal users to use single sign-on (SSO).

As we are using Windows Internal Database (WIM) to store AD FS configuration data, we do not need any additional servers for the database as WIM is included in Windows Server 2008 and later versions. Redundancy for WIM is possible when an AD FS farm is set up.

To support external users, we would need to set up an AD FS proxy server. In order to provide redundancy we would need to set up an AD FS proxy farm. This would require a minimum of 2 more servers.

The custom login page for external users can be created on the AD FS proxy server, which the external users would access. There is thus no need for additional servers.

Thus the minimum number of server we would require is four: two for the AD FS farm and two for the AD FS proxy farm.
