Your subscription contains VM1 and a private endpoint for azsql1.database.windows.net. You need to ensure the apps on VM1 can resolve the private endpoint's IP address. Which DNS zone should you create first?

To ensure VM1 resolves the private endpoint's IP address for azsql1.database.windows.net, you need to create a private DNS zone named privatelink.database.windows.net. Azure Private Link uses a specific DNS naming convention where private endpoints for Azure services are registered under a privatelink subdomain. This private DNS zone must then be linked to the virtual network containing VM1. Creating a public DNS zone (either database.windows.net or privatelink.database.windows.net) would not work because public DNS zones are for public resolution and would not contain the private IP address of your private endpoint. A private DNS zone named database.windows.net would be incorrect because it doesn't follow the privatelink naming convention required for Azure Private Link resolution.
