Microsoft Azure Administrator Associate AZ-104 Practice Question

Creating a single virtual network with two subnets allows you to segment the web and database tiers while maintaining secure communication between the VMs. Each subnet can represent a different tier, and you can apply network security groups for additional control. Deploying VMs in different virtual networks with overlapping IP address spaces would cause IP conflicts and prevent communication. Placing all VMs in the same subnet does not provide the required network segmentation. Using different resource groups organizes resources but does not affect network isolation.
