312-50V12 practice question 4 of 10
Which of the following tools can be used to perform a zone transfer?
Full set: 573 questionsA zone transfer (AXFR) is a DNS transaction used to replicate the entire database of a DNS zone from a primary server to a secondary server. Several command-line utilities and tools are designed for this purpose. nslookup (in interactive mode), dig, and host are standard DNS query tools on Windows and Unix-like systems, respectively, that have specific options to request a full zone transfer. Sam Spade is a classic graphical network query tool for Windows that includes a zone transfer function. These tools are commonly used by administrators for diagnostics and by attackers for reconnaissance.
B. Finger is a protocol for retrieving information about users on a remote system and has no DNS functionality.
F. Netcat is a versatile networking utility for reading/writing data across network connections but lacks built-in, high-level DNS zone transfer commands.
G. Neotrace is a graphical traceroute tool used for visualizing network paths, not for querying DNS zone data.
