Correct Answer: Configuring network devices with a primary and backup AAA server, along with an appropriate fallback method, so authentication continues if one server becomes unreachable
Explanation: Configuring primary/backup AAA servers with a sensible fallback method ensures continued authentication availability if one server fails, unlike single-server dependency, disabling authentication on failure, inconsistent backup policy, co-located redundancy (defeating its purpose), or removing all local fallback.
