Question
You have two Azure virtual networks in the East US Azure region as shown in the following table. The virtual networks are peered to one another. Each virtual network contains four subnets. You plan to deploy a virtual machine named VM1 that will inspect and route traffic between all the subnets on both the virtual networks. What is the minimum number of IP addresses that you must assign to VM1?

Explanation
Only a single IP address is needed. VM1 acts as a Network Virtual Appliance (NVA) - a router/firewall that inspects and forwards traffic. In Azure, a single NIC with one IP address can route traffic between multiple subnets across both virtual networks, as long as IP forwarding is enabled on that NIC and User-Defined Routes (UDRs) in each subnet point to VM1's private IP as the next hop. There is no requirement to place VM1 in each subnet or give it an IP per subnet. The routing is handled logically via UDRs at the Azure platform level, not by having multiple IP addresses on the VM.
