Question

What is the best solution that can be used to avoid having a single-point-of-failure when using RADIUS proxy servers?

Answer 1

Answer:

Create a Radius Server Group

Explanation:

Single point of Failure

A single point of failure is used in system to check that if system fails then entire system will stop from working.

Radius Proxy

When Network Policy Server is used as a Remote Authentication Dial-In User Service (RADIUS) proxy, NPS receives connection requests from RADIUS clients, such as network access servers or other RADIUS proxies, and then forwards these connection requests to servers running NPS or other RADIUS servers.

So, to avoid the single point of failure in radius proxy we create a radius server group.
