Which two statements about the requirements to configure inter-controller roaming are true? (Choose two.)

Controllers must be configured with the same mobility group name so they can exchange mobility messages and client state during a roam. Without a matching group name, the controllers treat each other as unknown peers and will not establish a mobility tunnel.

While it is a best practice to use the same virtual interface IP on all controllers in a mobility group, it is not listed as a hard requirement for enabling inter-controller roaming in this context.

The RF group name governs RF management and dynamic channel/power assignment between controllers, but it is not a prerequisite for inter-controller roaming itself.

Controllers participating in a mobility group do not need to reside on the same VLAN - they communicate over a Layer 3 mobility tunnel, so physical or VLAN adjacency is not required.

Clients roam by reassociating to an AP broadcasting the same SSID. If the SSID is not present on the destination controller, the client must perform a full new association rather than a seamless roam.
