Exam AZ-800 topic 11 question 2 discussion

The network requirements state: "All communications must occur over ExpressRoute." That means you need to create the conditions for that kind of connection: an ExpressRoute gateway and an ExpressRoute circuit connection. See for a detailed description: https://docs.microsoft.com/en-us/learn/modules/implement-hybrid-network-infrastructure/5-implement-azure-expressroute

https://learn.microsoft.com/en-us/azure/virtual-wan/virtual-wan-expressroute-portal You can either create the gateway when you create a new virtual hub, or you can create the gateway in an existing hub by editing it. Once the gateway is created, you can connect an ExpressRoute circuit to it. Answer is correct

Id be afraid there is going to be other flavors of this question- A hub and gateway creation is needed to bring this beast to life- but it doesnt seem they would go too deep- here is some links i researched before just going along with the express route answer- https://learn.microsoft.com/en-us/training/modules/implement-hybrid-network-infrastructure/6-configure-azure-virtual-wide-area-network https://learn.microsoft.com/en-us/azure/virtual-wan/virtual-wan-expressroute-portal https://learn.microsoft.com/en-us/azure/route-server/expressroute-vpn-support?source=recommendations
