3V0-24.25 Exam Results

Answer (Correct Order):

Select the target cluster in the workload domain.

Open Workload Management and select “Enable Supervisor Cluster”.

Choose cluster networking mode and stack.

Configure the control plane compute, networking, and storage policies.

Configure the workload network configurations.

Review, Validate, and Deploy Supervisor.

You start by selecting theexact vSphere cluster(in the workload domain) that will host the Supervisor, because Supervisor enablement is performedagainst a specific cluster. From there you launch the enablement workflow inWorkload Management(“Enable Supervisor Cluster”). Early in the wizard you must decide thenetworking mode(for example, VDS-based vs NSX-backed) and theIP stack, because those choices drive the remaining configuration screens and what inputs are required. Next you define theSupervisor control plane settings—compute sizing and the core policies the Supervisor will use (including storage policy selections and related defaults). After the control plane foundation is defined, you configure theworkload networkingused by namespaces and Kubernetes workloads (IP ranges, routing/LB integration depending on the selected mode). Finally, youreview/validateall inputs anddeployso the platform can create and configure the Supervisor control plane and supporting components.

In VMware Cloud Foundation (VCF) 9.0, the vSphere Kubernetes Service (VKS) leverages the vSphere Container Storage Interface (CSI) driver as the standard and supported mechanism for dynamic volume provisioning. The CSI provisioner, specifically identified by the string csi.vsphere.vmware.com, is the modern replacement for the legacy " in-tree " volume plugins. This driver serves as the bridge between the Kubernetes API and vSphere’s Cloud Native Storage (CNS) control plane located within vCenter Server.

When an administrator creates a StorageClass in VCF 9.0, it must reference this CSI provisioner to ensure that persistent volume claims (PVCs) are backed by vSphere datastores (such as vSAN, VMFS, or NFS). The transition to the CSI driver in VKS allows for advanced storage features not available in the legacy in-tree provisioner, including support for First Class Disks (FCD), volume snapshots, and resizing. Furthermore, VCF 9.0 documentation emphasizes that the legacy kubernetes.io/vsphere-volume in-tree provisioner has been deprecated and is not supported for modern VKS workload clusters. By using the csi.vsphere.vmware.com provisioner, VKS ensures that storage lifecycle management is fully integrated into the SDDC, providing developers with automated, policy-driven storage that adheres to the performance and availability profiles defined by the vSphere administrator via Storage Policy Based Management (SPBM).

VCF 9.0 documentation explicitly indicates thatvCenter upgrades and the Supervisor/cluster (Workload Management) upgrade are distinct, noting that “if you have only upgraded vCenter and not the cluster” then DevOps engineers have reduced permissions until the cluster is upgraded. This supports the stated standard that VKS/Workload Management lifecycle can be treated separately from vCenter. For the private registry requirement, VCF 9.0 provides an operational mechanism to authenticate and pull artifacts from private registries: “Registry secrets allow package and repository consumers to authenticate to and pull images from private registries,” implemented via a standard Kubernetes Secret of type kubernetes.io/dockerconfigjson.

Taken together, the standard implies (1)asynchronoushandling (separate lifecycle from vCenter) and (2)privatesourcing (images pulled from an internal registry with registry secrets). Therefore, selectingAsynchronous Privatebest matches both requirements in a single configuration choice, aligning with the documented separation of upgrades and the documented need to use authenticated access to private registries.

In VCF 9.0, cluster autoscaling is delivered as anoptionalcapability that requires installing theCluster Autoscaleras a standard package. The VCF 9.0 materials explicitly call out Cluster Autoscaler as an optionally installed package for vSphere Kubernetes Service, alongside other optional packages (for example, Harbor, Velero, Istio, etc.). The release information further emphasizes that autoscaling features (including newer behaviors such as scaling from/to zero for supported VKr versions) require that “the autoscaler standard package” be installed.

Operationally, installing the autoscaler package provides the controller that watches pending pods and node utilization signals and then drives the required changes in desired worker capacity. After that controller is present, you typically express scaling intent through the cluster’s declarative configuration (for example, worker pool/node pool constraints and limits) so the autoscaler can act within the boundaries you define. Without the autoscaler package, changing replica counts or expecting automatic node growth/shrink will not produce autoscaling behavior because the control loop that performs those actions is missing.
