Utility IoT meters and the city ERP share one flat VLAN because that is what the county already had. Which virtual-networking approach addresses that traditional flat-network risk?
Select an answer to reveal the explanation.
Short Explanation
Meters and ERP on one VLAN is like leaving the water-plant keys on the same hook as payroll. Overlay segments plus a distributed firewall put them in separate rooms without waiting for a new physical LAN. A bigger MTU or a Horizon pool just keeps them in the same hallway.
Full Explanation
Flat traditional VLANs let unrelated civic systems share broadcasts and unconstrained east-west paths. Virtual overlay segments isolate those systems logically, and the NSX-T distributed firewall can enforce micro-segmentation even when workloads share hosts. Increasing MTU, collapsing both into a Horizon pool, or disabling the distributed firewall leaves the flat-network risk in place.
