Question
An engineer is designing a wireless solution for a corporate campus, which includes two primary buildings: Research and Operations. The design must ensure:
- seamless mobility for employees moving between buildings
- support uninterrupted connectivity for real-time applications such as
Wi-Fi calling
- video conferencing and collaboration tools
The network infrastructure comprises two Cisco Catalyst 9800-80 WLCs - one deployed in each building - alongside a mix of CW9166I, C9136I, and CW9176I APs to deliver high-density Wi-Fi 6E coverage. With a significant number of mobile clients, the design must minimize latency, optimize load balancing, and facilitate efficient Layer 2 and Layer 3 roaming. Each building's 9800-80 WLC manages its local APs, and the solution must support 802.11 r/k/v while maintaining an effective mobility control plane. Which design approach leverages Cisco mobility group architecture to meet the requirements?
Options
- AAdd both 9800-80 WLCs in a single mobility group with no specific roles assigned, enabling peer-
- BAssign each 9800-80 WLC to separate mobility groups, one for each building, to isolate traffic and
- CEstablish the Operations building's WLC as an anchor controller, configuring the Research
- DDesignate the Research building's WLC as the primary controller and the Operations building's

Explanation
Placing both Catalyst 9800-80 WLCs in the same mobility group enables the controllers to share client context and coordinate roaming (including Layer 3 roaming) directly between them. This preserves real-time sessions (voice/video), supports 802.11 r/k/v for fast roaming decisions, and maintains an efficient mobility control plane without forcing unnecessary traffic tunneling or isolating roaming domains.
