Refer to exhibit.
A company has a multiple Arua implementation with three different locations named Headquarter, Branch, and Telecommuters.
The network design includes the following:
Headquarter APs terminate at the Mobility Controller (MC) cluster and propagate Corporate, Guest, and
Voice SSIDs
Branch APs terminate at the Branch Office Controller (BOC) and propagate Corporate and Voice SSIDs BOC reaches the Mobility Master (MM) through a VPNC.
Telecommuter RAPs terminate at VPNC and propagate Corporate and Voice SSIDs.
The Corporate SSID on the RAPs is split-tunnel, all other SSIDs are tunnel.
The network design requires minimal AP group and VAP configuration effor, while preventing unnecessary VAP propagation to lower hierarchy levels.
Following Aruba node hierarchy desing recommendations, which group hierarchy design helps meet these requirements?
