VMware Advanced VMware Cloud Foundation 9.0 vSphere Kubernetes Service 3V0-24.25 Exam Dumps: Updated Questions & Answers (May 2026)

VCF 9.0 explains pod fundamentals by describing how Workload Management introducesvSphere Pods, stating a vSphere Pod is “equivalent of a Kubernetes pod” and that it “runs one or more Linux containers.” This directly eliminates optionB, because a pod can includeone or morecontainers (not only one).

The vSphere 9.0 documentation further defines a KubernetesPodas “a group of one or more containerized applications that share such resources as storage and network,” and notes the containers inside a pod are “started, stopped, and replicated as a group.” That definition reflects Kubernetes’ scheduling and lifecycle model: Kubernetes treats the pod as the primary unit it places and manages together, which is why a pod is regarded as thesmallest deployable unitfor running containerized workloads in Kubernetes. OptionsCandDare incorrect because pods are Kubernetes objects (not “managed by Docker” as a smallest entity), and Kubernetes abstracts the underlying runtime/host so pods are not defined as being “deployed directly on the virtual machine” as a characteristic.

The vSphere Kubernetes Service (VKS) in VMware Cloud Foundation (VCF) 9.0 is designed as an " enterprise-ready " Kubernetes distribution that is deeply integrated with the SDDC stack. It provides several core capabilities out-of-the-box that would otherwise require manual configuration in a generic Kubernetes installation. The four primary capabilities identified are Authentication , storage integration , pod networking , and load balancing .

First, Authentication is handled via integration with the vSphere Supervisor, which acts as an identity proxy (using Pinniped and OIDC) to allow users to log in using their vSphere or external identity provider credentials. Second, storage integration is achieved through the vSphere CSI (Container Storage Interface), which connects Kubernetes Persistent Volume Claims (PVCs) directly to vSphere datastores. Third, pod networking is provided by an integrated CNI (typically Antrea), ensuring secure and high-performance communication between containers. Finally, load balancing is managed through the vSphere distributed switch or NSX, allowing for the automatic creation of Layer 4 load balancers for Kubernetes services of type LoadBalancer. While VCF 9.0 supports add-on services for logging and monitoring (as mentioned in Option B), the core architectural pillars provided natively by the VKS cluster lifecycle manager are those that bridge the gap between container orchestration and the underlying vSphere infrastructure, ensuring that pods have the network, storage, and access control they require to run production workloads.

When you build Kubernetes-aware policy constructs, “groups” are commonly used to collect objects so you can apply consistent controls (security posture, traffic rules, observability scope, etc.) to a set of endpoints. In VCF 9.0 documentation, the Kubernetes member types that can be used for group-based collection includeKubernetes NodeandKubernetes Serviceas supported member object categories. Nodes represent the worker compute endpoints that run workloads, while Services represent stable networking front-ends for sets of pods (and are often the anchoring object for policy and routing decisions at the Kubernetes layer). Using Node-based grouping helps apply policies to the infrastructure execution points where workloads run, and Service-based grouping helps apply policies consistently to application entry points and east-west communication targets, regardless of pod churn. This combination is especially useful in Kubernetes-centric operational models because it aligns policy scope with both (1) where workloads execute (nodes) and (2) how workloads are exposed and discovered (services).

Configure tab

In the context of VMware Cloud Foundation (VCF) 9.0 and vSphere with Tanzu, a vSphere Zone is a critical infrastructure object used to represent a failure domain. Specifically, it allows the vSphere Supervisor to span across multiple vSphere clusters (typically three) to provide high availability against a complete cluster failure. This " zoned " deployment model ensures that the Supervisor Control Plane and workload cluster nodes (VKS) are distributed across different physical racks or data centers.

To start the process of creating a new vSphere Zone, an administrator must navigate to the Configure tab. While the provided screenshot highlights a specific namespace (other-namespace), the creation of the underlying infrastructure zones is an administrative task performed at the vCenter Server or Cluster level. However, within any object’s view in the vSphere Client, the Configure tab serves as the primary gateway for all lifecycle management and setup tasks. For a vCenter-level configuration, the path is vCenter Server > Configure > vSphere Zones . Once a zone is created and mapped to a vSphere cluster, it can then be associated with a Supervisor. In the namespace-specific view shown, the Configure tab is also where the administrator would verify the placement of the namespace on a zoned Supervisor and manage the association with specific Supervisor Services. By clicking Configure , the administrator accesses the sub-menus required to define and modify these high-level SDDC constructs, bridging the gap between traditional vSphere resource management and the declarative Kubernetes environment provided by VKS.

VCF 9.0 describes backing up workloads on VKS clusters usingVelero(Velero Plugin for vSphere) and shows the backup command pattern scoping backup content bynamespace(for example, velero backup create ... --include-namespaces=my-namespace). This demonstrates thatNamespacesare a primary object type within backup scope (you choose which namespace content is captured). The same section explains that after backup execution,Kubernetes metadata is uploaded to the object store. “Kubernetes metadata” in this context includes standard namespaced resources that represent running workloads and how they are exposed, such asServices(a core Kubernetes API object used to provide stable access to pods).

In addition to namespace scoping, Velero’s selection model commonly includes filtering backed-up Kubernetes objects using selectors (for example, selecting subsets of resources), which aligns with the “objects identified by a label selector” option as an object-selection mechanism within the scope of what Velero captures from Kubernetes APIs (metadata/resources) once the namespace is targeted.

Therefore, the best match to the documented Velero workload-backup model is:Namespace,Service, andlabel-selected objectswithin the included namespace(s).

The errors described—specifically the memcache.go failure, the inability to fetch resource lists for Antrea, and the YAML context error—are classic symptoms of aConfiguration Context mismatch. In VCF 9.0, there are two distinct layers of API interaction: theSupervisor Cluster API(used for management tasks like creating clusters) and theGuest Cluster API(used for deploying workloads within the VKS).

When an administrator upgrades a Supervisor, the API endpoint or the available API groups may change. If the administrator attempts to run kubectl commands against a VKS cluster while their kubeconfig context is still pointing to the Supervisor (or vice versa), the client will encounter " mapping values " errors and " unable to handle request " errors because it is sending requests to an endpoint that does not recognize those specific resource definitions (like Antrea stats in the wrong context). To resolve this, the administrator must ensure they have switched to the correct context using kubectl config use-context < cluster-name > after the Supervisor update to ensure the local client is communicating with the correct API server and version of the Kubernetes binaries.

Configuration Sequence (in order):

Create the vSphere Namespace

Assign the zones

Select workload networking

Assign the zonal storage policy

Define resource quotas / limits

Grant RBAC / permissions

A zonal vSphere Namespace is created as a standard namespace first, then “zonalized” by associating it with one or morevSphere Zonesso workloads can be scheduled according to zone placement rules. You start bycreating the namespacebecause it is the tenancy and governance container where networking, storage access, quotas, and permissions are applied. Next, youassign the zones, since zone association is what makes the namespace “zonal” and determines where Kubernetes workloads (and their node pools) are allowed to land.

With zones set, you configureworkload networking, because namespaces must have the correct network attachment and IP behavior for the workloads that will be placed across the selected zones. Then youassign the zonal storage policy, ensuring that persistent volumes can be provisioned using storage that is valid/available for the zone placement model you selected. After networking and storage access are defined, you setresource quotas/limits(CPU, memory, storage) so multi-tenant consumption stays within governance boundaries. Finally, yougrant RBAC/permissionsso the right DevOps/users can consume the namespace and provision clusters/workloads under the enforced controls.

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.

The documented behavior of kubectl edit is that it opens the object manifest in a local text editor, and the editor it launches is controlled by environment variables. In the VCF 9.0 documentation (Workload Management / Supervisor operations), the procedure explicitly states: “The kubectl edit command opens the namespace manifest in the text editor defined by your KUBE_EDITOR or the EDITOR environment variable.”

If the administrator’s environment does not have KUBE_EDITOR or EDITOR defined (or they point to an invalid/interactive-less editor in the current session), kubectl edit may not open the expected editor workflow, and the admin may not see the normal confirmation after saving and exiting. Setting KUBE_EDITOR (preferred for kubectl-specific behavior) or EDITOR ensures kubectl launches a known-good editor, allowing the manifest to be modified, saved, and then submitted back to the API server when the editor exits. The same documented requirement also applies to editing other Kubernetes objects (such as a VKS cluster manifest) because the kubectl edit mechanism is identical.

In VCF 9.0 Workload Management, workload backup for VKS clusters (and vSphere Pods) is performed using Velero, specifically theVelero Plugin for vSpherefor Supervisor/VKS scenarios. The documentation describes that you must firstprovide an S3-compatible object storeas part of installing and configuring the Velero Plugin for vSphere, because backup data (Kubernetes metadata and volume snapshot data movement) relies on object storage rather than “namespace storage.” The backup workflow further indicates that when you create a backup, the system uploadsKubernetes metadata to the object store, and persistent volume snapshot handling is coordinated through the plugin components (Snapshot/Upload custom resources).

Therefore, the correct configuration pattern is to point Velero’s backup target (BackupStorageLocation) at anS3-compatible object storeendpoint so metadata and snapshot payloads have a durable destination. This aligns with the documented prerequisite that object storage is required to enable backup/restore operations for persistent workloads, and it is the mechanism Velero uses to store backup artifacts for later restore operations in VKS environments.
