This is perhaps a little bit overengineered.
You can see on the left side of the screen on your Windows 10 or
Windows 11 box you've got Hyper‑V, and you have copies of the
Windows Server 2022 evaluation. I would suggest that you set up a,
doesn't have to be four domain,
but I would say three domain anyway, a multi‑forest,
multi‑domain environment.
So, in this case, in your original forest1,
you've got a forest root and a child domain. I would suggest you
have two domain controller VMs in the root one and the child. And
then for forest2, you really just need the forest root. If you want
to throw the child in there, that's fine.
And I wouldn't even say that you need two domain controllers in the forest root.
I just would say that for one of those root domains you want to have two
domain controllers because part of the objectives involve your understanding
how Active Directory replication works between domain controllers in the
same site and domain and across domain controllers, across subnets, across
Active Directory sites, all right? And then assuming you've got a free trial
going with Azure, you can build out a relatively simple virtual network.
Now, again, this is perhaps a bit overengineered.
Do you need a client subnet?
Not necessarily,
but by creating a domain subnet with one or two Windows
Server domain controllers there, this can give you practice
in extending your domain environment.
Now, how would you do the extension?
You see the middle part of this diagram? You've got a
site‑to‑site virtual private network.
Now there are a number of ways you can stand up a site‑to‑site VPN. I've given you some guidance on this in the course files.
