If BIND is authoritative for zone a, and is not authoritative for zone 
b, but zone b is configured in BIND's zone file, and x.zonea.com is 
CNAME'd to y.zoneb.com.

When DNS client queries to this BIND for x.zonea.com, it gets the 
authoritative answers for both x.zonea.com and y.zoneb.com, certainly 
y.zoneb.com is a fake one.

How DNS client handle this case?
