Good Day, Jason
Couple of comments there on the last Q:
1-) I think you meant that "VM network must be able to handle 2.34 Gbps not 2.43 Mbps"
2-) You have to add a port group for Backup Network.

3-) Try to minimize the standard switches a bit, and tell the user to put X number of port groups per a standard switch.
4-) what about policies..?? what do you mean by putting policies in lower right corner..?? I think all to be Reject. Not a challenge In addition, you mentioned that request twice.
5-) It'e better to make a special connector for fail-over connection. I mean, if a port group will have an active and a passive connections, the active will be a standard connector and the passive will be another one.
Nice Q, brother
