When performing a DNS resolution diagnosis, which command provides detailed query information and record data from specified DNS servers?
arp
dig
tcpdump
nslookup
The 'dig' (Domain Information Groper) command is specifically designed for querying DNS servers to receive a comprehensive breakdown of DNS lookup information. This command allows administrators to pinpoint issues with DNS resolutions by offering detailed responses from DNS servers. Other given options, although related to network operations, serve purposes distinct from direct DNS querying: 'nslookup' is another DNS querying tool but generally provides less detailed information than 'dig'; 'tcpdump' captures and analyzes network packets; and 'arp' is used for viewing and modifying the ARP cache, which resolves IP addresses to MAC addresses.
