Which DNS zone transfer method is used to copy zone data from a primary server to a secondary server?

Explanation:
Copying the entire set of DNS records for a zone from a primary (master) DNS server to a secondary (slave) is done through a zone transfer. The standard full transfer method is AXFR, which transfers every record in the zone to ensure the secondary has a complete and consistent copy. Records like SOA, NS, and MX are DNS record types that describe authority, name servers, and mail routing, not the transfer mechanism itself. Some systems also support IXFR for incremental updates, but AXFR is the classic method used to copy the complete zone data.
