A hacker is attempting to use nslookup to query Domain Name Service (DNS). The hacker uses the nslookup interactive mode for the search. Which command should the hacker type into the command shell…

'locate' is not a valid nslookup interactive mode command and does not exist in the nslookup command set.

'request' is not a recognized nslookup interactive mode keyword and will produce an error if entered.

The 'set type=ns' command is the correct nslookup interactive mode syntax for changing the query record type to NS (Name Server). Within the interactive shell, all configuration changes use the 'set' keyword followed by the parameter, so 'set type=ns' tells nslookup to request NS records in subsequent queries.

'transfer' is not a valid nslookup subcommand - zone transfers are initiated differently using 'ls' with the '-d' flag, not a 'transfer type=' syntax.
