3V0-24.25 Dumps with Practice Exam Questions Answers

VCF 9.0 defines aVCF CLI contextas aconfiguration setfor a specific endpoint (for example, a Kubernetes cluster, vSphere Supervisor, or VCF Automation) and explains that a context stores the key connection parameters such asendpoint,context type,path to kubeconfig, andcredentials. This aligns directly with optionC, because vcf context create is used to create anamedcontext that encapsulates the access parameters needed to work with a specific Supervisor or VKS cluster and to switch between multiple environments without rewriting configuration each time.

The documentation further shows vcf context create being used to connect either to aSupervisor endpointor to aworkload (VKS) cluster(by providing workload cluster name/namespace or by using a generated kubeconfig), which is exactly the multi-tenant operational pattern in the question. While authentication is part of what happens during context creation (for example, creating a configuration that includes a JWT for Kubernetes API access), the command’s purpose is broader: it creates the reusablecontextobject that defineswhereandhowthe CLI connects.

VCF 9.0 explicitly documents thatVKS supports two CNI options: Antrea and Calico, and that thesystem-defined default CNI is Antrea. This directly eliminates Flannel and Cilium as default supported options for VKS clusters on Supervisor in this context. VCF 9.0 also describes how a vSphere administrator can view or change this setting in the vSphere Client underSupervisor Management → Configure → Kubernetes Service → Default CNI, further reinforcing that Antrea is the baseline/default choice.

From a policy perspective in the question, the requirement is Kubernetes-layer observability and control of pod communications “without additional licensing or overlay complexity.” Antrea is presented in VCF 9.0 as the default CNI and is implemented usingOpen vSwitch, with networking and network policy capabilities provided at the Kubernetes layer for pods and services. Because it is the documented default (and supported) option for new VKS clusters, selectingAntreabest aligns with the “default supported option” requirement.

Kubernetes Service

When adding a Kubernetes cluster to anexisting vSphere Namespace, the workflow is initiated from within that namespace’s context in the vSphere Client. The administrator first opens the target namespace (as shown in the left navigation where the namespace is selected), then uses theKubernetes Servicearea to create and manage Kubernetes clusters associated with that namespace. In the namespaceSummaryview, theKubernetes Servicetile/card provides the entry point for cluster lifecycle actions, typically via an action link such asManage(and from thereCreate Cluster). This is because the Kubernetes cluster is anamespace-scoped resourcein the Supervisor environment: it inherits namespace-level policies and configuration such as permissions/RBAC, resource limits, storage policies, and networking selections that have already been defined for that namespace. Navigating to other areas likeStorageorNetworkis used to validate or adjust prerequisites (for example, storage policy availability or network settings), but the actual “create cluster” operation is launched fromKubernetes Servicewithin the namespace to ensure the cluster is created under the correct tenant boundary and governance model.

A ReplicaSet is a core Kubernetes workload controller used in VKS clusters to maintainavailability and steady-state capacityfor stateless applications. Its primary purpose is to ensure that adesired number of identical pod replicasare running continuously. If a pod is deleted, crashes, or is evicted because a node fails, the ReplicaSet detects that the current number of matching pods has dropped below the target and immediately creates replacement pods to restore the requested replica count. Conversely, if too many matching pods exist (for example, due to manual creation or a transient surge), it scales down by deleting excess pods to return to the desired state.

This behavior makes ReplicaSets foundational to reliable, self-healing application operation in Kubernetes and therefore in VKS. In practice, administrators and DevOps teams usually interact with ReplicaSets indirectly through higher-level controllers likeDeployments, which manage rolling updates and revisions while using ReplicaSets underneath to enforce the replica count for each version of an application. Options A, B, and D map to other Kubernetes objects (Service, StatefulSet, and DaemonSet respectively), not ReplicaSet.

The VCF 9.0 documentation explicitly states that“the VKS exposes three layers of controllers to manage the lifecycle of a VKS cluster.”Those three controller layers map directly to the answer choices:

Cloud Provider Plug-in: VKS-provisioned clusters include components needed to integrate with vSphere Namespace resources, including aCloud Provider Plug-inthat integrates with the Supervisor and supports infrastructure-integrated functions (for example, passing persistent volume requests to the Supervisor which integrates with Cloud Native Storage).

Cluster API: The documentation describesCluster APIas providing declarative APIs for “cluster creation, configuration, and management,” including resources for the VMs and cluster add-ons.

Virtual Machine Service: TheVirtual Machine Serviceprovides declarative APIs to manage VMs and associated vSphere resources, and is used to manage the lifecycle of the control plane and worker node VMs that host a VKS cluster.

CNI and CSI are important cluster components, but the document distinguishes these from thethree controller layersresponsible for lifecycle management.
