Municipal employee WLAN depends on 802.1X. How should RADIUS/AAA be designed for resilience?
Select an answer to reveal the explanation.
Short Explanation
If 802.1X is the front door, RADIUS is the locksmith on call. Two (or more) AAA boxes beat one lonely VM that naps during patching. Public demo servers and fake forever-success caches are how cities lock themselves out—or let everyone in.
Full Explanation
Enterprise WLAN security depends on AAA availability; redundant RADIUS servers with proper failover or load balancing keep 802.1X authentication working when a node fails or is maintained. A single RADIUS instance is a critical single point of failure for employee SSIDs. External demo servers and fabricated always-success caching break confidentiality, accountability, and operational control.
