A city packet walk shows guest Ethernet frames carried inside IP packets between prepared hosts. Which SDN overlay building block is that?
Select an answer to reveal the explanation.
Short Explanation
Overlay is stuffing a neighborhood letter inside a city-mail envelope so it can ride any street. The guest Ethernet frame goes inside an IP packet—tunneling—not a snapshot, a display protocol, or a threat event.
Full Explanation
SDN overlay logical networks use Layer-2-in-Layer-3 tunneling and encapsulation so the VM topology is decoupled from the physical underlay; in NSX-T that encapsulation is Geneve between tunnel endpoints. vSphere snapshots capture VM state on storage. Horizon BLAST remotes a desktop session, and Carbon Black event forwarding is endpoint telemetry, not overlay encapsulation.
