Tess King is using the nslookup command to craft queries to list all DNS information...

Tess King is attempting to gather all DNS records from a target zone. This process is referred to as a zone transfer (AXFR), which is typically performed by secondary name servers to synchronize DNS data with the primary. If improperly secured, attackers can initiate unauthorized zone transfers to enumerate valuable information such as:

Hostnames

IP addresses

Mail servers

Name servers

CEH v13 defines a zone transfer as a crucial step in DNS enumeration.

From CEH v13 Official Courseware:

Module 3: Scanning Networks

Topic: DNS Enumeration → Zone Transfers

CEH v13 Study Guide states:

“A zone transfer (AXFR) is a DNS transaction used to replicate DNS databases. Attackers can exploit this feature to extract all DNS information from an improperly secured server.”

Incorrect Options:

A. Zone harvesting is not a formal term.

C. Zone update refers to DNS dynamic update operations (e.g., DDNS).

D. Zone estimate is not a DNS-related process.
