Network configuration files are defined in what format for PowerShell?

In the context of Azure, the network configuration files are defined in formats such as JSON or YAML for PowerShell. It is so because the resources of Azure including network configurations can be provisioned and managed by using the Azure Resource Manager (ARM) templates which are mainly written in JSON( JavaScript object notation). These templates enable the definition of the configuration of networks in a well-structured format which allows you as a user to deploy and manage the resources of Azure including components of networking very well.

Here is a basic example of how an ARM( Azure Resource Manager) template defines a virtual network and a subnet:-

{
  “$schema”: https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#,
  “contentVersion”: “1.0.0.0”,
  “resources”: [
    {
      “type”: “Microsoft.Network/virtualNetworks”,
      “apiVersion”: “2021-02-01”,
      “name”: “MyVirtualNetwork”,
      “location”: “West US”,
      “properties”: {
        “addressSpace”: {
          “addressPrefixes”: [
            “10.0.0.0/16”
          ]
        },
        “subnets”: [
          {
            “name”: “MySubnet”,
            “properties”: {
              “addressPrefix”: “10.0.0.0/24”
            }
          }
        ]
      }
    }
  ]
}
