How many networks does clustering need ?

I know there is a public network for all application communication and one
for hearbeat .
Are there any more ?
Does one connect the hearbeat network to like a local hub for the nodes or
to the same public network ( dont know if im stating this right) ? Whats
best practise to set up the private hearbeat ?But networks, I am assuming you mean network cards on the server. It is
recommend two; one for the Live check and one for public traffic on the node.
Thanks!
