Question 210
A lightweight access point temporarily loses its controller WAN link in a remote branch. The design must specify what local client forwarding, authentication and cached policy behavior is supported. Which design decision is essential?
Explanation
Correct Answer
FlexConnect can support remote-site designs with local forwarding and certain survivability behaviors, subject to platform, authentication and WLAN configuration. The controller outage does not guarantee identical behavior for every security mode. Test the branch mode and failure case before promising clients continued service.
Incorrect Answers
If their data path requires the controller across the failed link, connectivity may not survive. A proper design distinguishes central from local switching.
DNS can locate services but does not define wireless data forwarding or local authentication behavior during controller loss. That is a WLAN mode design choice.
A passive hub is not a supported wireless survivability mode. This would not specify valid controller-disconnected WLAN operation.
