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 SOA record in the contoso.com zone.
Does this meet the goal?

A. Yes
B. No

Show Suggested Answer

Suggested Answer: B 🗳️
Modify the NS record, not the SOA record.
Note: The SOA record stores information about the name of the server that supplied the data for the zone; the administrator of the zone; the current version of the data file; the number of seconds a secondary name server should wait before checking for updates; the number of seconds a secondary name server should wait before retrying a failed zone transfer; the maximum number of seconds that a secondary name server can use data before it must either be refreshed or expire; and a default number of seconds for the time-to-live file on resource records.

The answer is correct. You should create a DNS NS record set named www in the company.com zone. - The NS must be created at the apex of the zone name, the top-level zone name. - The NS record identifies the Azure DNS name server assigned to the zone. - The top-level NS record set is created automatically and cannot be deleted. - You can create, modify, and delete NS record sets for delegated zones. This question is about Azure DNS and not domain name provider DNS.
