The municipal airport overlay must hand off to physical routers at the civic edge. Which gateway role is that north-south peering?
Select an answer to reveal the explanation.
Short Explanation
Tier-0 is the airport exit road to the city's physical routers. Tier-1 stays on the agency side and does not skip that exit. A standard vSwitch or a Horizon UAG is not the NSX north-south gateway.
Full Explanation
A Tier-0 gateway provides north-south connectivity and peers with physical routers, typically with BGP, as the provider-like handoff for the municipal airport overlay to the civic edge. Tier-0 is the airport exit road to the city's physical routers where agency traffic leaves the NSX fabric. A Tier-1 that never connects to a Tier-0 remains on the agency side and does not replace that physical peering role. A vSphere Standard Switch is a host virtual switch and is not the physical BGP speaker for the NSX fabric. Horizon Unified Access Gateway is an EUC edge for remote desktop access, not an NSX Tier-0 north-south gateway. Exam caveat: BGP neighbor configuration and uplink details live on Tier-0 designs; do not place ISP peering on a Tier-1 that is meant to link north to Tier-0. Operational check: open Networking Tier-0 Gateways, confirm the airport Tier-0 shows uplinks and BGP neighbors toward physical routers, verify a Tier-1 hangs south of that Tier-0 for tenant segments, and reject Standard Switch or UAG as the north-south NSX gateway. 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.
