The other day I posted up the environment for VCAP5-DCA (DCA550), here’s the same for DTA
If only one last-octet is listed for a machine with several nics, all have that last octet (if the interface is configured).
Note that all of the VMs listed there are “top level” or “first virtualization” level. If you are building this nested (like on Workstation) these are the VMs in Workstation.
There are many more components to the exam environment incl replication and vMA but all of those run nested on the hosts you see in that diagram.
