Why each option
When a user crafts queries to retrieve all DNS information for a domain, including name servers, hostnames, MX records, and other zone details, they are attempting to perform a zone transfer.
Zone harvesting (or enumeration) typically refers to collecting individual records or partial information, often through various queries, rather than obtaining the complete zone data in a single operation like a transfer.
A zone transfer (specifically an AXFR or full zone transfer) is the process of retrieving the entire database of DNS records for a specific domain or zone, which includes all the types of information listed in the question.
A zone update refers to modifying specific records within a DNS zone, not retrieving all existing information from it.
A 'zone estimate' is not a standard or recognized operation in DNS.
