Step-by-step explanation:
The Primary DNS Zone refers to the authoritative zone that contains the main DNS records for a particular domain. It is responsible for resolving domain names to IP addresses and vice versa. This zone is typically hosted on a primary DNS server, which acts as the primary source of information for the domain.
For example, let's consider a domain called example.com. The Primary DNS Zone for example.com would contain records like the A record, which maps the domain name to the IP address of the server hosting the website. It may also include other records like the MX record for mail servers and the NS record for authoritative name servers.
