Planning-commission operators still need the NSX UI and API when one Manager appliance is down. Which cluster role provides that high availability?
Select an answer to reveal the explanation.
Short Explanation
Three Manager appliances in a cluster are the commission's spare front counters. If one is closed, the UI and API stay open. An Edge, a standard switch, and Horizon Cloud Connector are not that management HA group.
Full Explanation
The NSX Manager cluster provides high availability for the UI, API, management plane, and central control plane so planning-commission operators can keep working when one Manager appliance is down. Three Manager appliances in a cluster are the commission's spare front counters—if one is closed, the UI and API stay open. A single standalone Edge runs centralized data-plane services; it is not the management-plane cluster and cannot replace Manager HA. vSphere Standard Switches are per-host virtual switches, not a Manager HA construct. Horizon Cloud Connector is an EUC component and does not provide NSX Manager clustering. Exam caveat: Manager cluster health depends on supported node counts and majority; the exam point is that the Manager cluster—not Edge, Standard Switch, or Horizon—backs UI and API availability. Operational check: with a multi-node Manager cluster, take one node offline for maintenance, confirm UI and API remain available, and document that operators did not fail over management to an Edge or Horizon Cloud Connector. 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.
