For remote branches requiring no local controller and VLAN-based local internet breakout, which deployment mode should be used?

FlexConnect local switching is the correct deployment mode for remote branches needing no local controller and VLAN-based local internet breakout. In FlexConnect local switching, client data traffic is switched locally at the access point (AP) directly to the local network, allowing for efficient internet breakout without backhauling traffic to a central controller. This reduces WAN link utilization and latency. Control traffic, however, is still sent to the central Wireless LAN Controller (WLC). Central switched mode would send all client traffic, including internet-bound traffic, back to the central WLC, which is inefficient for local internet breakout. Auto-anchor mobility is used for inter-controller roaming and guest access, not for local internet breakout in remote branches. Asymmetric tunneling is a feature related to mobility and roaming, not a deployment mode for local internet breakout.
