Question
A customer has two Cisco wireless controllers named WLC-A and WLC-B. Each controller is in a different building on a campus. The WLCs have different Layer 3 interfaces and broadcast the same SSIDs from their respective APs. Users must remain connected to the same VLAN and maintain their IP addresses during roaming from the APs that are attached to WLC-A and WLC B. Which action accomplishes the requirement?
Options
- ACreate a mobility group between the two WLCs to allow auto-anchoring.
- BCreate an SSO cluster to ensure that client sessions sync between WLCs.
- CEnable 802.11r on each SSID on both WLCs to allow caching of the PMK.
- DEnable AP groups using the same name on both WLCs for each group.

Explanation
To maintain the same VLAN and IP address for users roaming between APs attached to different WLCs, a mobility group should be created between WLC-A and WLC-B. This allows for inter- controller roaming, where client sessions are maintained across different controllers, ensuring that users can move across the campus without losing connectivity or changing IP addresses.
