The city's 311 portal needs NAT and other north-south services that cannot run only as in-kernel tables on every ESXi host. Which SDN building block provides those centralized services?
Select an answer to reveal the explanation.
Short Explanation
Some jobs stay in the kernel on every host—switching and distributed firewalling. NAT and several north-south services need a dedicated appliance, and that appliance is the NSX Edge node, not a disk group or a VDI broker.
Full Explanation
NSX Edge nodes are service appliances that run network services that cannot be fully distributed to every hypervisor, including NAT, load balancing, VPN, and the centralized Tier-0/Tier-1 services that face the physical network. Distributed firewall remains an in-kernel east-west control, not a NAT engine. vSAN stores VM files. Horizon Connection Server is an EUC broker, not an NSX centralized-services node.
