Samba4 does not support any clustered operation. In it's primary role
as an AD domain controller, this simply isn't needed - multiple DCs are
expected.

The fileserver could with work be clustered - indeed ctdb was first
developed in Samba4 - but there is no work in this area at this time.

If I understand it right, I do not have to cluster anything. I can run two or more samba4 DCs. If one fail the other will take over.
Or the other way, if two samba4 DCs own the same domain, ex. Test.local, they load balance the domain?

Correct. Load balancing is up to the client, but yes it should just
work.

In this case there is a need for replication. What is the status quo? Will the DCs replicate their databases?
Where do I set replication? In my smb.conf?
