C is correct.
Man dig
-t type
This option indicates the resource record type to query, which can be any valid query type. If it is a resource record type supported in BIND 9, it can be given by the type mnemonic (such as NS or AAAA). The default query type is A, unless the -x option is supplied to indicate a reverse lookup. A zone transfer can be requested by specifying a type of AXFR. When an incremental zone transfer (IXFR) is required , set the type to ixfr=N. The incremental zone transfer contains all changes made to the zone since the serial number in the zone’s SOA record was N. All resource record types can be expressed as TYPEnn, where nn is the number of the type. If the resource record type is not supported in BIND 9, the result is displayed as described in RFC 3597.
I tried both NS and MX and i get the similar results from both of those, but then i started to examen the picture and the results from the command and it clearly says that NS is used if you look at the picture and after:
; http://www.example. IN NS <—– NS was used
So dig -t ns http://www.example.org command was used.
Does someone have a valid reasoning for the answer? because option C is the one providing the output in the picture…
i think the correct answer is C because there is “NS” at the end of line 8, when we enter the command in option “B” we get A at the end of line 8
If B is the answer then D would be correct to as this is the default behavior.
I think C is correct as the Question section replies with NS
