Creating a virtual network and then adding the subnet is the appropriate approach for deploying a virtual subnet in Azure. In Azure, a virtual network serves as the foundational component for building clouds, allowing resources to communicate with each other securely and efficiently. By first establishing a virtual network, you define the overall address space and then subdivide this space into one or more subnets.

Subnets allow you to segment your network based on requirements such as security policies, traffic management, and organizational needs. After the initial setup of a virtual network, adding subnets is straightforward and allows you to build a structured, organized environment for your Azure resources. This method supports deployment scenarios like isolating environments for production, testing, and development within a single virtual network.

While other options mentioned serve important roles in Azure, they do not address the specific task of deploying a subnet. For instance, directly assigning public IP addresses to VMs pertains to networking but doesn’t involve subnet creation. Using Azure Monitor for network insights focuses on monitoring and diagnostics rather than deployment. Implementing VPN connections deals with secure remote access and networking but does not directly create subnets.
