In a Cisco Catalyst 9800 SSO deployment using Link Aggregation Group (LAG) for network interface redundancy, the SSO pair — WLC1 (active) and WLC2 (standby) — must both have their physical interfaces connected to the network infrastructure as part of the LAG bundle. LAG on the 9800 in an SSO configuration is implemented as a multi-chassis LAG across both the active and standby controllers. This means both WLC1 and WLC2 contribute physical member links to the port channel, and the connected switches must have LACP or PAgP bundle members from both controllers in the same port channel group. When an SSO failover occurs — WLC1 fails and WLC2 takes over as active — the LAG remains operational because WLC2 ' s physical links are already established members of the bundle and continue forwarding traffic without any link renegotiation. If only WLC1 had LAG connectivity and WLC2 had independent links, an SSO failover would cause a LAG topology change requiring re-convergence, introducing downtime. WLC3 is a separate N+1 backup controller joined via a mobility tunnel — not part of the SSO pair and its LAG configuration is independent.

When designing a wireless network to support diverse services — including data, voice, video, and location tracking — across a distributed enterprise with a main office and 10 branch locations, the two primary design factors directly shaping the RF and capacity architecture are the number of wireless devices requiring access and the type of site where the survey will be performed. The device count (Option B) drives AP density, channel reuse planning, capacity modeling, and controller licensing requirements. Each service type — particularly VoWLAN and video — imposes strict per-client throughput and latency constraints that must be multiplied across the concurrent device population. The type of site (Option C) determines the survey approach, attenuation characteristics, coverage requirements, and antenna selection. A warehouse, hospital, or open-plan office each demands a fundamentally different RF design. Options A and D are organizational considerations, not technical RF design inputs. Option E (power sockets) is an installation logistics concern, not a wireless design factor.

Cisco ' s mobility group architecture enables seamless client roaming between WLCs by establishing a trusted peer relationship and shared mobility domain. When two Cisco Catalyst 9800-80 WLCs are placed in the same mobility group, they establish CAPWAP mobility tunnels enabling both Layer 2 and Layer 3 roaming with session continuity including IP address preservation. Within the same mobility group, WLCs exchange client state information, allowing 802.11r Fast BSS Transition, 802.11k neighbor reports, and 802.11v BSS Transition Management to function across controller boundaries. No specific primary or secondary roles are assigned within a mobility group — all members are peers with equal standing for roaming purposes, which is precisely what Option D describes. Option A incorrectly implies a hierarchical structure that does not exist in mobility group peer relationships. Option B separating the WLCs into different groups would break inter-building roaming since clients would experience a full re-authentication cycle. Option C imposing an anchor relationship is appropriate only for guest WLANs. Reference: WLSD Study Guide — Mobility Group Architecture, Inter-Controller Roaming, 802.11r/k/v Fast Roaming Design.
