A customer wants to deploy two Cisco 9800 WLCs in a high availability SSO configuration. The customer wants multiple links between the WLCs and wants the core switches to ensure redundancy in the event of a failure. The core switches are in a VSS pair, and both switches must have split-link connectivity to the WLCs. The WLCs must not experience any drops when the core switches fail over. Which connectivity solution must be used to meet the requirements?

Answer researched independently against supporting documentation; not a published source answer key. Derived technical reasoning from cited primary documentation; no recovered public answer key. Cisco recommended VSS split-uplink topology uses a port-channel on each controller and directly back-to-back redundancy ports.
