Is it possible for to resolve a zone fqdn?

[Chris Holman]

If the dns masterfile for zone1 (dns.zone1.com) contains an NS entry for a
dns of a subsequent zone2 (dns.zone2.zone1.com) is it possible to resolve
the zone fqdn "zone2.zone1.com" to the IP of "dns.zone2.zone1.com"?

If I added a CNAME record to the masterfile of zone1 would this conflict
with the zone2 NS entry i.e.

# zone1.com masterfile
zone2.zone1.com.     IN    NS     dns.zone2.zone1.com.
dns.zone2.zone1.com. IN    A      xxx.xxx.xxx.xxx
zone2.zone1.com.     IN    CNAME  dns.zone2.zone1.com.
