Cisco 500-220 Exam With Confidence Using Practice Dumps

This is the number of tunnels that each hub needs to support in a hub-and-spoke Auto VPN deployment with two NAT-mode hubs with dual uplink connections and 50 remote sites with a single uplink connection. This can be calculated by using the formula for the hub tunnel count in a hub-and-spoke topology1:

Hub Tunnel Count = (H x (H - 1) / 2 x L1) + (H x S x L1 x L2)

Where H is the number of hubs, S is the number of spokes, L1 is the number of uplinks for the hubs, and L2 is the number of uplinks for the spokes. In this case, H = 2, S = 50, L1 = 2, and L2 = 1. Therefore,

Hub Tunnel Count = (2 x (2 - 1) / 2 x 2) + (2 x 50 x 2 x 1) Hub Tunnel Count = (2 x 1 / 2 x 2) + (200 x 2) Hub Tunnel Count = (2 / 2 x 2) + (400) Hub Tunnel Count = (1 x 2) + (400) Hub Tunnel Count = 2 + 400 Hub Tunnel Count = 402
