Question

Your company owns the domain contoso.com registered with a third-party domain registrar. You create a public DNS zone named contoso.com in Azure DNS and add several A and CNAME records. However, when external clients query these records, they do not resolve to the values you configured in Azure DNS. What must you do to make Azure DNS authoritative for the domain?

Accepted Answer

Update the name server (NS) records at the domain registrar to point to the Azure DNS name servers assigned to the zone.

Answer

Create a virtual network link between the Azure DNS zone and the VNet used by the clients.

Answer

Add an SOA record to the Azure DNS zone that references the registrar's name servers.

Answer

Change the Azure DNS zone type from public to private so it can be resolved externally.
