  Centralized wireless control plane: The same innovative RF features that Cisco has today in Cisco Unified Wireless Network (CUWN) deployments will be used in Cisco SD-Access Wireless as well. Wireless operations stay the same as with CUWN in terms of Radio Resource Management (RRM), client onboarding, and client mobility and so on which simplifies IT adoption. LISP control plane Management: The fabric-enabled WLC integrates with the LISP-based control plane. The control plane is centralized at the WLC for all wireless functions. The WLC is responsible for the AP image management and configuration, RRM, and client session management and roaming. The WLC interacts with the host-tracking database on the control plane node for client MAC address registration with SGT and Layer 2 virtual network ID and its mapping with RLOC. The virtual network information is Layer 2 virtual network information, and it is mapped to a VLAN on the fabric edge node. The WLC is also responsible for updating the host-tracking database with roaming information for wireless clients.

  C is correct answer • The fabric-enabled WLC integrates with the LISP control plane. The control plane is centralized at the WLC for wireless functions. Figure 8. Fabric-enabled WLC • The WLC is still responsible for APimage/configuration, RRM, clientsession management and roaming, and all the other wireless control plane functions. • For fabric integration: • For wireless, the client MAC address is used as the EID. • Interacts with the Host Tracking database on the control-plane node for client MAC address registration with SGT and VNI. • The VN information is mapped to a VLAN on the fabric edges. • The WLC is responsible for updating the Host Tracking database with roaming information for wireless client
