3V0-24.25 Exam Dumps : Advanced VMware Cloud Foundation 9.0 vSphere Kubernetes Service

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).

In VCF 9.0, ingress is described as part ofVKS cluster networking. The documentation’s VKS Cluster Networking table lists“Cluster ingress”and identifies its role asrouting inbound pod traffic. It further clarifies that this function is delivered by athird-party ingress controller, and explicitly namesContouras an example (“you can use any third-party ingress controller, such as Contour”).

That mapping is exactly what optionAdescribes: Contour is deployed to provideingresscapabilities so that inbound requests from outside the cluster can be routed to Kubernetes services and pods according to ingress rules. In other words, Contour is not a storage component (that would align to CSI/CNS/pvCSI), not a node lifecycle manager (that is handled by VKS/Cluster API/VM Service), and not an infrastructure health monitoring tool (that would be metrics/observability tooling). VCF 9.0 positions Contour specifically within theingresspart of the networking feature set, makingAthe correct answer.

VCF 9.0 describes VKS as providing self-service, declarative lifecycle management for Kubernetes clusters and explicitly identifiesCluster APIas the mechanism that enables Kubernetes-style lifecycle automation. The documentation states that “The Cluster API provides declarative, Kubernetes-style APIs for cluster creation, configuration, and management,” and that its inputs include resources describing “the virtual machines that make up the cluster” plus “cluster add-ons.” This directly maps to automated lifecycle management: a desired-state YAML is reconciled by controllers that create, update, and maintain the control plane and worker node resources without manual, imperative procedures.

The same VCF 9.0 content also notes VKS exposes “three layers of controllers” for lifecycle management and lists Cluster API as one of those layers, reinforcing that Cluster API is foundational for ongoing cluster operations (create, scale, upgrade, reconcile). Contour is an ingress controller (traffic routing), kubeadm is a Kubernetes bootstrap tool (not the VKS lifecycle controller framework), and Grafana is observability/visualization (not cluster lifecycle).
