That explains what you are trying to achieve, but not really why.

If you are trying to create an Ansible script to create a new domain, 
then you do not require any DC GUID's, as the first DC in your new 
domain will have a new unique GUID.

If you are trying to create an Ansible script to recreate a failed 
domain from a backup, then this works in pretty much the same way.

You should never try to backup a DC, only the domain. If a single DC 
fails, replace it with a new DC. If all the DC's fail, then restore the 
domain from a backup, you can use 'samba-tool domain backup' to create 
the required backup.
