A customer requires their wireless network to be fully functional, even if the wireless controller fails. Which wireless design supports these requirements?
Correct Answer: A
This is because FlexConnect is a feature that allows wireless access points to operate in standalone mode when they lose connectivity to the wireless LAN controller. FlexConnect enables the access points to switch the data traffic locally, without sending it to the controller, and to perform local authentication, without relying on the central server. FlexConnect also allows the access points to maintain the wireless network functionality, such as SSIDs, security policies, and QoS, even if the wireless controller fails. FlexConnect is suitable for branch locations or remote offices that have limited WAN bandwidth or reliability.
