Question #: 18
Topic #: 2
An administrator must create amulti-zone vSphere Supervisordeployment in a VMware Cloud Foundation (VCF) environment. What is the primary purpose of this configuration?
A.
To create isolated security domains using NSX micro-segmentation.
B.
To enable cross-site vSAN stretched clusters for data replication between data centers.
C.
To provide high availability for the Supervisor Cluster and vSphere Kubernetes clusters.
D.
To simplify the management of network pools and IP address ranges.
Amulti-zone Supervisorin VCF 9.0 is designed to deliverplatform resiliency and high availability at the vSphere cluster (zone) failure-domain level. The VCF 9.0 documentation states that a multi-zone Supervisor “leverages three vSphere clusters” (each mapped to a vSphere Zone) and that these zones are used by both “workloads and Supervisor management components to deliver high availability,” exposing “each cluster as an independent, consumable availability zone,” resulting in a “resilient, HA-capable platform.”
This is reinforced in the vSphere Zones guidance: deploying the Supervisor onthree vSphere Zones spreads the control plane VMs across three zones, providing “cluster-level high availability” that protects the Supervisor control plane against asingle cluster-level failure(one control plane VM per management zone).
Because VKS (vSphere Kubernetes Service) runs on Supervisor, distributing Supervisor control plane and workload placement across zones improves overall availability of Supervisor services and Kubernetes consumption in that Supervisor instance.
