Well yeah - there's no end to the odd things asked... ;-)

Then you'd use nslookup and query the zone - either for SOA or NS.
Because, DNS is the repository that actually stores whether a particular
nameserver is *authoritative*.

Why? That's a subtly different question. Surely that's not truly the
answer you want? Didn't you want to know if a particular server was
authoritative for a zone, rather than all the things it was
authoritative for(and / or hosting)?
You started by saying you moved a DNS zone, then wanted to find out if
where it moved to, was authoritative - as opposed to *all* the things it
was authoritative for. And lets not forget - merely listing the zones a
DNS server serves, does not mean it is authoritative for those zones -
you need to query DNS to find that out.

Tells you nothing, really, though. They could merely be secondary or
caching zones. Doesn't mean a server is authoritative, merely that it's
hosting.

*I* didn't ;-)
Somebody else actually wanted the info. The resource records are key,
though, to understanding the roles of the DNS servers for the relevant
zones.
