Question

How do you create a "Fault Tolerant" AD FS server?

a) Set up multiple AD FS servers in a load-balanced configuration.
b) Install AD FS on a server with high fault tolerance by default.
c) Contact Microsoft Support to enable "Fault Tolerant" mode.
d) Implement fault tolerance at the DNS level.

Answer 1

To establish fault tolerance for AD FS servers, the best method is to set up multiple servers in a load-balanced configuration, ensuring service continuity in case of individual server failure.

Step-by-step explanation:

To create a fault-tolerant AD FS server, the correct approach is to set up multiple AD FS servers in a load-balanced configuration. This ensures that if one server fails, the others can continue to provide the service without interruptions. Installing AD FS on a single server with high fault tolerance does not prevent service disruption if that one server fails. Contacting Microsoft Support to enable "Fault Tolerant" mode is not a standard procedure for achieving fault tolerance. Lastly, implementing fault tolerance at the DNS level alone is insufficient as it does not prevent the AD FS service itself from experiencing a single point of failure.
