   Which topology type is supported in each noncore region in a Cisco SD-WAN Multi-Region fabric environment with three or more regions?

   • Aany topology type
   • Bfull mesh and partial mesh
   • Chub and spoke
   • Dfull mesh

   Show answer

   Answer: A

   Explanation

   Network Topology Multi-Region Fabric provides the flexibility to use different network topologies in different regions. For example, region 1 can use a full mesh of Cisco Catalyst SD-WAN tunnels, while region 2 can use a hub-and-spoke topology, and Region3 can use a full mesh topology with dynamic tunnels. We recommend using a full mesh of tunnels for the overlay topology of the core region (region 0). https://www.cisco.com/c/en/us/td/docs/routers/sdwan/configuration/hierarchical-sdwan/hierarchical-sdwan-guide/h-sd-wan-basics.html
