The only advantage is if you have a high traffic environment, otherwise
it isn't required, just use the DC's as the domain nameservers. If you
do have a lot of traffic (most of which will have nothing to do with the
AD domain (google etc) ), the caching/forwarding server will use data
from its cache, or ask its forwarders, or if it is something inside the
AD DNS domain, it will ask an AD DC.
