Your company registers a domain name of contoso.com.
You create an Azure DNS zone named contoso.com, and then you add an A record to the zone for a host named www that has an IP address of 131.107.1.10.
You discover that Internet hosts are unable to resolve www.contoso.com to the 131.107.1.10 IP address.
You need to resolve the name resolution issue.
Solution: You modify the name servers at the domain registrar.
Does this meet the goal?

A. B.B
Modify the Name Server (NS) record.
https://docs.microsoft.com/en-us/azure/dns/dns-delegate-domain-azure-dnsThe solution provided, "modify the name servers at the domain registrar", does not necessarily meet the goal of resolving the name resolution issue.
The problem with the current configuration could be due to a number of reasons such as incorrect DNS records or incorrect DNS settings. However, modifying the name servers at the domain registrar would not address these issues directly.
When you register a domain name, the domain registrar typically provides default name servers that are authoritative for the domain. If you have created an Azure DNS zone for the same domain name, you need to configure the domain registrar to use Azure DNS name servers instead of the default ones.
To do this, you would need to update the NS (Name Server) records at the domain registrar to point to the Azure DNS name servers. Once the changes propagate, the Azure DNS zone would become authoritative for the domain name and would handle all name resolution requests for that domain.
So, in summary, modifying the name servers at the domain registrar can potentially meet the goal of resolving the name resolution issue, but only if it involves updating the NS records to point to the correct Azure DNS name servers.
