    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 risk was documented by the architect? (Choose the best answer.)

A.

Network administrators are not familiar with NSX-T Data Center solutions.
