Microsoft Azure Administrator Associate AZ-104 Practice Question

Creating separate subnets within the same virtual network (VNet) is the best method to segment the network. Subnets allow you to divide the VNet into smaller, isolated sections where you can place groups of VMs. This facilitates internal isolation and enables you to apply subnet-specific network security policies. Deploying separate VNets would isolate the VMs but would complicate management and inter-VNet communication. Using network security groups (NSGs) helps control traffic but doesn't inherently provide network segmentation based on IP addressing. Configuring different virtual network gateways is unnecessary for isolating groups within the same VNet.
