Your company has multiple branch offices across North America. You have an Azure subscription. The subscription contains three virtual networks in the US East Azure region that have a hub-and-spoke topology. The hub network contains an Azure VPN gateway that provides Site-to-Site (S2S) and Point-to-Site (P2S) VPN connectivity for the branch offices and remote users. You need to implement ExpressRoute and migrate the hub-and-spoke topology to Azure Virtual WAN. The solution must provide fully meshed connectivity for the following network traffic: - Traffic from a branch office via ExpressRoute to the other branch offices and the virtual networks - Traffic from a branch office via the S2S VPN to the other branch offices and the virtual networks - Traffic from the remote users via the S2S VPN to the branch offices and the virtual networks - Traffic from the virtual networks to the branch offices - Traffic between the virtual networks How many virtual network gateways are required?
