If a new solution only has a Networker Server & Data Domains (DD & DDBoost) with no storage nodes where can the NWK Server databases live?

Apparently they can live on DD is that correct? Is it of all them (Configuration, Media, Client file indices and Jobs) or just some?

Same with the NMC server that is located on the same NWK server, can its NMC database live on the DD?

If it can be done, is it a good idea?

Why : You could virtualize the NWK Server with minimal configuration if you wanted to.
