Public-housing application VMs need software Layer 2 domains that span prepared hosts without recabling the civic underlay. Which NSX-T feature provides that?
Select an answer to reveal the explanation.
Short Explanation
Logical switching is the software hallway: segments stretch L2 across prepared hosts without recabling the underlay. HA restarts VMs, vSAN stores disks, and Instant Clone clones desktops — none of those is that LAN.
Full Explanation
NSX-T logical switching uses segments to provide virtual Layer 2 connectivity across transport nodes for public-housing application VMs, independent of physical recabling of the civic underlay. Logical switching is the software hallway: segments stretch L2 across prepared hosts without asking facilities to recable ToR VLANs for every move. vSphere High Availability restarts virtual machines after a host failure; it is not an L2 fabric. vSAN stretched clusters are a storage topology and do not replace overlay switching. Horizon Instant Clone is desktop provisioning, not civic overlay switching. Exam caveat: logical switching still requires transport-zone membership and a working underlay for TEPs; independence from recabling is not independence from IP underlay health. Operational check: create a segment, attach housing VMs on two hosts in the overlay zone, verify L2 without underlay VLAN recabling, and confirm HA, vSAN stretch, and Instant Clone were not used as the LAN feature. Keep the civic framing visible in runbooks so the next operator can restate why the correct control fits the agency outcome, why each distractor fails by concept, and which Manager or fabric view proves the design after change.
