A static-stub zone involves an iterative query, the potential for a referral, and then potentially recursion to follow the referral.

Conditional forwarding (a zone of type forward) involves a recursive query. If the answer is not forthcoming and 'forward only;' is set, the result is a SERVFAIL back to the client. There is no possibility that the DNS server so configured will follow referrals.
