問題文
An architect is sizing the head-end appliances for an Auto VPN rollout that will have 3 dedicated datacenter hubs and 60 branch spokes. Every appliance has both WAN uplinks active, and the topology is hub and spoke. How many Auto VPN tunnels will exist in the organization?
選択肢
- 360 tunnels, because each spoke builds one tunnel to each hub for each of its own uplinks.
- 183 tunnels, because one tunnel is built for each pair of appliances that exchanges routes.
- 732 tunnels, because the hubs also build a full mesh among themselves on top of the spoke tunnels.
- 720 tunnels, because each spoke reaches each hub over its two uplinks and nothing else counts.
