What correctly describes mobility groups in wireless networking?

• A. Support for only one WLC
• B. A maximum of 24 WLCs can share client state and loading info
• C. Sharing of encryption keys only
• D. Lack of client re-authentication during roaming

Answer: (B)

Mobility groups in wireless networking are designed to enhance the user experience by allowing multiple Wireless LAN Controllers (WLCs) to share important client-related information, such as client state and load balancing data. The correct description highlights that a maximum of 24 WLCs can be part of a mobility group, enabling them to share tracking information for clients, which is crucial for seamless roaming. This feature allows a client to move between different access points managed by different WLCs within the same mobility group without needing to re-authenticate, thereby improving network performance and user experience. This functionality is vital in scalable wireless environments, where numerous access points are deployed, as it ensures continuous and uninterrupted connectivity for mobile clients moving across the network.
