8 Gig Express Route. 2 GB per ER scale unit. Therefore number of scale units = 8/2 = 4 https://www.wwt.com/article/microsoft-azure-virtual-wan-cloud-networking-architecture

Answer is correct. Basic virtual WAN supports Site-to-site VPN only Standard virtual WAN supports ExpressRoute User VPN (P2S) VPN (site-to-site) Inter-hub and VNet-to-VNet transiting through the virtual hub Azure Firewall NVA in a virtual WAN https://docs.microsoft.com/en-us/azure/virtual-wan/virtual-wan-about -------- 8G/2G = 4 Express Route Scale Units and Connectivity: Similar in concept to VPN scale units, customers seeking to deploy Express Route connectivity into their Virtual WAN Hubs will incur costs for the scale units provisioned in that hub, with options ranging from 1 to 10 with each representing 2Gbps of ER throughput. https://www.wwt.com/article/microsoft-azure-virtual-wan-cloud-networking-architecture

this is where you'll see the scale unit for ExpressRoute and VPN. 1 scale unit of VPN = 500 Mbps 1 scale unit of ExpressRoute = 2 Gbps The requirement for Expressroute throughput is 8Gbps so 4 ER scale units are needed. The answer is correct. https://learn.microsoft.com/en-us/azure/virtual-wan/virtual-wan-faq

I think the first requirement which is 10 sites that will connect to your virtual wan hub doesn't matter much as one virtual wan hub supports up to 1000 sites.

I don't see any reference on Azure Documentation (learn.microsoft.com) talking about 4 Scale Units give 8GB. When I look for Virtual WAN Scale Units, all I find is this doc: https://learn.microsoft.com/en-us/azure/virtual-wan/virtual-wan-faq#for-user-vpn-point-to-site--how-many-clients-are-supported According to this chart 4 scale units is wrong. So can someone explain; where did my thinking go wrong.

Each scale unit represents 500Mbps of VPN throughput.

ER Scale units are 2GBps, 500Mbps is for P2S & S2S.

What are Virtual WAN gateway scale units? A scale unit is a unit defined to pick an aggregate throughput of a gateway in Virtual hub. 1 scale unit of VPN = 500 Mbps. 1 scale unit of ExpressRoute = 2 Gbps. Example: 10 scale unit of VPN would imply 500 Mbps * 10 = 5 Gbps. https://docs.microsoft.com/en-us/azure/virtual-wan/virtual-wan-faq#what-are-virtual-wan-gateway-scale-units
