An administrator is tasked with making an existing vSphere Supervisor highly available by adding two additional vSphere Zones. How should the administrator perform this task?

Answer

A. You cannot add an existing Supervisor to a new vSphere Zone. Correct
B. Create a new multi-zone deployment and assign an existing vSphere cluster to it.
C. Create a new vSphere Zone and add the Supervisor to the new vSphere Zone.
D. Select Configure, select vSphere Zones, and click Add New vSphere Zone.

Explanation

In VMware Cloud Foundation 9.0 and vSphere Supervisor architectures, the decision to deploy a Single- Zone or a Multi-Zone Supervisor is made at the time of initial enablement. A Single-Zone Supervisor is tied to a specific vSphere Cluster. A Multi-Zone Supervisor requires a minimum of three vSphere Zones (each mapped to a cluster) to be defined before the Supervisor is deployed so that the Control Plane VMs can be distributed for high availability. Currently, there is no supported "in-place" migration path to convert a deployed Single-Zone Supervisor into a Multi-Zone Supervisor by simply adding zones later. If an organization requires the high availability provided by a three-zone architecture, the administrator must decommission the existing Single-Zone Supervisor and then re-enable the Supervisor Service using the Multi-Zone configuration wizard. This design ensures that the underlying Kubernetes Control Plane components are correctly instantiated with the necessary quorum and anti-affinity rules that can only be established during the initial "Workload Management" setup phase.
