No, it is a systemd thing.

Not sure, I run a DHCP server on my DC, but not in the way you are
proposing, see the Samba wiki for more info.

Yes, but the --server-role and --dns-backend are defaults and as such
are not really required.

Wrong, the domain name, also known as the workgroup, is really the
NetBIOS domain name. This should not be confused with the NetBIOS name,
which is the hosts short name in UPPERCASE.
If you are confused, don't blame me or Samba, blame Microsoft, they
came up with the names.

You don't, Samba will set it for you from your shorthostname.

Yes, provided the output from 'hostname -s' is 'dc1' ;-)
