Cluster API (CAPI) is a foundational Kubernetes sub-project integrated into VMware Cloud Foundation (VCF) 9.0 via the vSphere Kubernetes Service (VKS) . It is designed to bring declarative, Kubernetes-style APIs to cluster creation, configuration, and management. In a VCF environment, the vSphere Supervisor acts as the " Management Cluster, " utilizing CAPI to automate the entire lifecycle of workload clusters (formerly known as TKG clusters). Instead of requiring manual infrastructure provisioning, CAPI allows administrators to define the desired state of a Kubernetes cluster-including its version, node count, and underlying hardware resources-using YAML manifests. The vSphere Kubernetes Service then works to reconcile the current state of the infrastructure with this defined desired state. This transition to declarative management is a core component of VCF 9.0, as it enables " Kubernetes-on-Kubernetes " orchestration. This ensures that Day 1 operations (deployment) and Day 2 operations (scaling, patching, and upgrading) are consistent, repeatable, and less prone to human error. While other options describe components like cert-manager (Option A), Container Network Interfaces (Option C), or vulnerability scanners (Option D), only Option B accurately identifies CAPI's role as the engine for automated, policy-driven cluster lifecycle management within the VMware SDDC stack.
3V0-24.25 Exam Question 27
An administrator is modernizing the internal HR and payroll applications using vSphere Kubernetes Service (VKS). The applications are composed of multiple microservices deployed across Kubernetes clusters, fronted by Ingress controllers that route user traffic through Avi Kubernetes Operator. During testing, it is discovered that manually creating and renewing TLS certificates for each Ingress resource is error-prone and leads to periodic outages when certificates expire. The requirements also mandate that all application endpoints use trusted certificates issued through the corporate certificate authority (CA) with automatic renewal and rotation. Which requirement can be met by using cert-manager?
Correct Answer: C
cert-manager addresses the operational risk described (manual creation/renewal causing outages) by making certificate lifecycle management anative, declarative Kubernetes workflow. Instead of treating TLS certificates as manually managed files, cert-manager extends the Kubernetes API with custom resources such asCertificate,Issuer, andClusterIssuer, so certificates and their issuing policies become first-class objects that can be version-controlled and automatically reconciled. This directly satisfies the requirement to usetrusted certificates issued through the corporate CA, because an Issuer/ClusterIssuer can represent that corporate CA integration and define how certificate requests are fulfilled. Once configured, cert-manager continuously monitors certificate validity andautomatically renews and rotatescertificates before expiration, then updates the referenced Kubernetes Secrets so Ingress endpoints remain protected without human intervention. In a vSphere Supervisor / VKS environment, VMware also uses cert-manager on the Supervisor for automated certificate rotation in platform integrations (for example, rotating certificates used by monitoring components), reinforcing the model of automated rotation rather than manual certificate handling.
3V0-24.25 Exam Question 28
A cloud operations team is managing multiple Supervisor Clusters across two regions. Each region hosts its own vSphere Kubernetes clusters, integrated through a federated service mesh to enable consistent service connectivity and policy enforcement across environments. The application team wants to expose a multi-tier microservice named "GovApp", which includes front-end, API, and database services distributed between the two regions. Uniform traffic routing, identity, and security policies are also needed for these workloads regardless of the cluster or region in which they are deployed. To meet these requirements, the architects decide to create a Global Namespace that spans both Supervisor Clusters. Which two statements describe the requirements for a Global Namespace in a vSphere Kubernetes Service Mesh deployment? (Choose two.)
Correct Answer: A,B
A Global Namespace in a service-mesh-driven, multi-cluster design is fundamentally anorganizational and policy boundarythat lets platform teams treat multiple Kubernetes namespaces-across multiple clusters /regions-as one logical application domain. That is whyBis correct: it defines an application boundary spanning clusters, which is exactly what "GovApp" needs when its tiers are distributed across regions but must still behave as one application. It also explains whyAis correct: the value of a Global Namespace is that you can applyconsistent identity, security, and traffic policiesacross all member namespaces and clusters, rather than configuring them separately per cluster. This supports uniform mTLS/authorization posture, consistent service-to-service access rules, and standardized routing behaviors regardless of where a service instance runs. The other options describe outcomes that may be enabled by additional service-mesh features, but they are not the corerequirementsthat define a Global Namespace: distributed ingress/egress is not guaranteed simply by the namespace construct, automatic workload placement is typically handled by schedulers/placement engines rather than the namespace boundary, and centralized logging is an observability capability outside the namespace requirement itself.
3V0-24.25 Exam Question 29
An administrator is tasked to protect a VKS cluster at a point in time. To satisfy the request, the administrator creates a pre-provisioned snapshot of the target cluster. Drag and drop the four configuration tasks Into the correct order from " Configuration Steps " on the left and place them into the " Configuration Order " on the right. (Choose four.)
Correct Answer:
Explanation: Configuration Order (in order): Verify the name of the original VolumeSnapshot object in the Supervisor. Create a VolumeSnapshotContent object. Create a VolumeSnapshot object. Verify that the VolumeSnapshot is marked with ReadyToUse as true. Apre-provisioned snapshotworkflow means the snapshot already exists at the Supervisor/storage layer, and you are "importing" it into Kubernetes by creating the Kubernetes objects that reference it. That's why the first step is toidentify/verify the exact snapshot nameas it exists in the Supervisor context-this is the authoritative identifier you must point to when you create Kubernetes snapshot metadata. Next, you create theVolumeSnapshotContentobject, which represents theactual snapshot on the storage backendand includes the handle/reference to that pre-existing snapshot. With the content object in place, you then create theVolumeSnapshotobject, which is theuser-facing Kubernetes object(namespaced) that binds to the pre- provisioned VolumeSnapshotContent (either explicitly or via binding rules). Finally, you validate the outcome by checking that theVolumeSnapshot shows ReadyToUse: true, confirming the binding succeeded and Kubernetes can use the snapshot for restore/clone workflows.
3V0-24.25 Exam Question 30
Which four capabilities are provided by a VMware Kubernetes Service (VKS) cluster?
Correct Answer: A
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.
