There are applications which use IPv6 addressing.
Network administrators are not familiar with NSX-T Data Center solutions.
Hosts can only be configured with two physical NICs.
There is an existing management cluster to deploy the NSX-T components.
Dynamic routing should be configured between the physical and virtual network.
There is a storage array available to deploy NSX-T components.
Which constraint was documented by the architect? (Choose the best answer.)

1. A. Dynamic routing should be configured between the physical and virtual network.
2. B. There are applications which use IPv6 addressing.
3. C. Hosts can only be configured with two physical NICs.
4. D. There are enough CPU and memory resources in the existing management cluster.
