It should be the other DC. Think about it. Does 8.8.8.8 know anything
about any host in your samba domain? Your samba dns configuration
should then use forwarders that point to something that knows how to
resolve external names. Could be 1.1.1.1, 8.8.8.8 or whatever.

FWIW, 1.1.1.1 is Cloudflare. If you must use public dns for external name
resolution, I prefer Cloudflare over Google. Less tracking and all of that
stuff.
