Exam 300-430 topic 1 question 250 discussion

It is either B or C FlexConnect is designed for branch deployments where APs can continue functioning even if they lose connectivity to the centralized WLC. To ensure users remain connected when the WLC connection fails but 802.1X authentication is still available, the best option is Authentication Local / Switch Local. Authentication Local → The AP handles 802.1X authentication locally, allowing clients to authenticate even if the WLC is unreachable. Switch Local → The AP forwards client traffic directly to the local switch, reducing reliance on the WLC for data plane operations. Why not the other options? A. Authentication Central / Switch Central → Requires WLC connectivity for both authentication and switching. If the WLC fails, clients will be disconnected. C. Authentication Central / Switch Local → Still relies on the WLC for authentication, meaning users will be disconnected if the WLC is unavailable. D. Authentication Local / Switch Central → Authentication works locally, but traffic is still sent back to the WLC, which can create problems if the WLC is down.

To ensure that users remain connected to the FlexConnect APs even if the connection to the Wireless LAN Controller (WLC) fails, the Authentication Central/Switch Local configuration should be implemented. This configuration provides the following benefits: Authentication Central: User authentication (e.g., 802.1X) is handled by the WLC when it is reachable. This ensures centralized control over authentication policies. Switch Local: Traffic is forwarded locally at the AP, even if the WLC is unreachable. This allows users to stay connected and continue accessing local resources during a WLC outage. This setup is ideal for branch offices where maintaining connectivity during WLC failures is critical.

C is also not wrong as it mention that existing users should stay connected. B would be the best options for new sessions as far as 802.1X stays online
