Question
You deploy a public Azure DNS zone named contoso.com and import DNS records from your domain provider to the DNS zone.
You need to ensure that name resolution requests for contoso.com can be resolved by using the public Azure DNS zone.
What should you do?
A. Add the NS records of your domain registrar’s name servers to the Azure DNS zone.
B. Create a child Azure DNS zone in contoso.com.
C. Create an MX or TXT DNS record set in contoso.com.
D. Add the NS records of the Azure DNS zone to the domain registrar.
Answer
D. Add the NS records of the Azure DNS zone to the domain registrar.
Explanation
To use the records and record sets created in an Azure Public DNS zone with a custom domain, you need to add the Azure DNS name servers to your domain registrar name server settings. The domain registrar uses its own name servers, and those must point to the NS records Azure assigned to the Azure DNS zone.
Creating MX or TXT records will not allow you to manage your custom domain DNS records. Adding the domain registrar’s name servers to the Azure DNS zone will not allow you to manage the record. Creating a child Azure DNS zone is mainly for managing subdomains, but you still need to add the Azure DNS zone name servers to the domain registrar’s settings first.
