My answer is D.
An iterative query is one of in which the name servers is expected to provide the best information (also knowns as referral if the servers is not authoritative for the name) based on what the servers knowns from local zone files or from caching.

I will go with B, as recursive forces the server to get the answer to a client. Iterative lets the server give an error to the client if it cannot find it locally.

Iterative makes the server ask another server, if it can't answer directly. Sorta like 'I don't know Jack, but Joe knows Jack, Talk to him.'

And the answer is ....
Correct Answers: D
An Iterative name query is one in which a DNS client allows the DNS Server to return the best answer it can give based on its cache or zone data.
If the queried DNS Server does not have an exact match for the queried name, the best possible information it can return is a referral (that is, a pointer to a DNS Server authoritative for a lower level of the domain namespace). The DNS client can then query the DNS Server for which it obtained a referral.
