What does the term "transport zone" refer to in NSX-T?

The term "transport zone" in NSX-T refers specifically to a logical construct that defines the scope within which overlay and VLAN segments can be created and utilized. This framework enables the segmentation of workloads at a level that supports both overlay and VLAN-based networking, allowing for the appropriate connectivity and isolation of virtual networks.

By defining a transport zone, you provide a boundary for traffic that can be mapped to virtual network segments. In essence, the transport zone dictates whether the segments created under it are operating in overlay mode, which relies on IP encapsulation for communication among virtual machines, or in VLAN mode, which connects to physical networks through VLAN tagging.

The concept of a transport zone is critical for determining how virtual networks interact with each other and with the physical network infrastructure, thereby facilitating network flexibility and the automation of network services within NSX-T.

While other choices refer to relevant elements in networking, they do not align with the specific definition of a transport zone in the context of NSX-T's architectural framework.
