答案：A
A mobility group is a set of controllers, identified by the same mobility group name, that defines the realm  of seamless roaming for wireless clients. By creating a mobility group, you can enable multiple controllers  in a network to dynamically share information and forward data traffic when inter-controller or inter-subnet  roaming occurs. Controllers in the same mobility group can share the context and state of client devices as  well as their list of access points so that they do not consider each other’s access points as rogue devices. With  this information, the network can support inter-controller wireless LAN roaming and controller redundancy.
