True or false: In Azure, subnets are created as either private or public.

In Azure, subnets do not inherently exist as either private or public. Instead, the concept of public or private is determined by the usage of the resources within the subnets. When you create a subnet in Azure, it is typically associated with a Virtual Network (VNet). The distinction of whether a subnet is considered 'public' or 'private' is largely based on whether the resources in that subnet have public IP addresses assigned.

For example, a subnet that hosts virtual machines (VMs) with public IP addresses is often referred to as public, as those machines can be directly accessed from the internet. Conversely, a private subnet consists of resources that do not have public IP addresses, making them inaccessible from the internet and often used for backend services and databases.

Understanding this helps clarify that the binary classification of subnets as public or private is not inherently a characteristic of the subnets themselves but rather a reflection of the IP addressing and configuration standards applied to the resources within them. This understanding is crucial for establishing secure network architectures in Azure.
