Windows 2012 Hyper-V, network priority

Hi,

Got three four (4) network.

(2x NICs) Network A = Production + Management (I know this is not recommended, but lack NICs)

(2x NICs) Network B = iSCSI

(1x NIC) Network C = Cluster Traffic and CSV

(1x NIC) Network D = Live Migration

Question:

1. I know that Network C is the preferred Cluster Traffic and CSV network (Network Priority = 1000).

     ---> If network C fails, will Cluster Traffic and CSV pass through my Network D automatically ?

2. Do I need to Team my NICs for my iSCSI network ?

3. Can I Team Cluster Traffic and CSV network NICs ?

4. All NICs with "allow cluster network traffic" enabled, will this allow hearbeat to pass through this NICs?

Thanks,

Paul
