What is a "VLAN Backed Segment" in NSX-T?

A "VLAN Backed Segment" in NSX-T refers to a segment that is directly connected to an existing VLAN in the physical network. This allows virtual machines and workloads within the NSX-T environment to communicate with physical workloads while still leveraging the advanced features of NSX-T.

By connecting an NSX-T segment to a VLAN, organizations can integrate their virtual networking seamlessly with existing Layer 2 networks. This setup is beneficial for scenarios where workloads need to interact with legacy systems or other services that reside outside the virtualized environment, providing connectivity while retaining the advantages offered by NSX-T, such as micro-segmentation and network automation.

The context of other choices indicates that they refer to different aspects of networking within NSX-T that do not specifically address the nature and purpose of VLAN Backed Segments. For instance, an isolated network segment would not have external connectivity to VLANs and is more about segmentation within the NSX-T environment. Similarly, a legacy networking setup, while relevant to NSX-T, does not specifically highlight the connection to existing VLANs in the way that a VLAN Backed Segment does. Finally, a segment that supports encrypted traffic only describes a specific security feature rather than the connectivity aspect that is central to VLAN
