Explanation

SD-Access Site Interconnection Methods

Cisco SD-Access supports two primary methods for connecting multiple fabric sites: SD-Access Transit (Option A) and IP-Based Transit (Option D). SD-Access Transit uses a dedicated transit control plane node to extend the LISP/VXLAN fabric between sites, preserving SGT (Scalable Group Tag) policy across the entire domain. IP-Based Transit leverages existing IP infrastructure (such as MPLS or the internet) between sites, using standard IP routing to connect fabric edges, though with reduced policy continuity compared to SD-Access Transit.

Why the distractors are wrong:

• B (Fabric Interconnect) is a term associated with Cisco UCS (data center server connectivity), not SD-Access networking
• C (Wireless Transit) is not a defined SD-Access interconnection method
• E (SAN Transit) relates to Storage Area Networks and has no relevance to SD-Access fabric connectivity

Memory Tip

Think "SI" - SD-Access and IP": the two transit types that matter for fabric-to-fabric connectivity. If a transit method doesn't logically bridge campus networks (SAN, wireless, UCS fabric), eliminate it immediately on the exam.
