How do you create and configure Azure virtual networks? Sign in to the Azure portal. Create a new virtual network. Provide basic details like subscription, resource group, name, region, IP address range, and subnets. Configure advanced options such as DDoS protection, service endpoints, DNS servers, etc. (optional). Configure security using network security groups (NSGs) to control inbound and outbound traffic (optional). Review the configuration settings. Click "Create" to start the deployment. Monitor the deployment progress. Once created, further configure features like virtual network peering, VPN gateways, network security rules, route tables, etc., as needed. Remember to consult Azure documentation and resources for detailed instructions on virtual network configuration and management.
