What should the architect suggest as the simplest solution that meets the requirements?

A) Add APs in a dedicated AP group to support only the guest network SSID.
B) Have a dedicated mobility controller in the DMZ managed by the same MM.
C) Double the number of APs and controllers
D) Use MultiZone, and put a mobility controller in the DMZ.
