An architect is helping an organization with the Conceptual Design of an NSX-T Data Center solution.
This information was gathered by the architect during the Discover Task of the Engagement Lifecycle:
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 risk was documented by the architect? (Choose the best answer.)

A design for a large-scale NSX-T deployment includes multiple vCenter servers. Which NSX-T construct is used to define the scope of hosts and clusters that a single NSX-T installation can manage and prepare as transport nodes?

Correct answer: B
A Transport Zone defines the boundary for NSX logical switching. It dictates which hosts (and therefore which VMs on those hosts) can participate in a particular set of NSX logical networks. A single transport zone can span multiple clusters and even multiple vCenter servers that are registered with the same NSX Manager, as shown in the diagram.
