A municipal top-of-rack switch delivers many VM port-group VLANs to the cluster on one physical uplink. Which vSphere and physical attachment model is that?
Select an answer to reveal the explanation.
Short Explanation
One driveway carrying many painted lanes is a trunk. The ToR sends several port-group VLANs down that uplink, and vSphere still depends on that physical VLAN model. Overlay can reduce tenant VLAN sprawl later, but it does not redefine this attachment as promiscuous mode or a guest-side transport zone.
Full Explanation
Traditional vSphere VLAN networking still depends on the physical switch trunking multiple 802.1Q VLANs to the host uplinks so each port group can tag its VLAN. That is the attachment model in this scenario. NSX overlay can later reduce the number of tenant VLANs the physical fabric must carry, but it does not erase the underlay or turn a transport zone into in-guest VLAN tagging. Promiscuous mode is a port-group security policy, not a substitute for trunking.
