How is everyone studying for CCIE data Center ACI?
Rack rental ? virtual software ?
INE DC rack rental is delay
you can use Cisco sandbox or cisco sales connect
You can also consider to use dCloud, where they have several ACI topics, good for studying the ACI GUI but unfortunately, we couldn't test the Data Plane on virtual ACI Lab
but I think it is a good start to get our hands dirty on the ACI
just my 2 cents
