Pass the VMware VCAP-VKS 3V0-24.25 Questions and answers with CertsForce

VCF 9.0 distinguishes betweenbacking up the Supervisor control planeandbacking up workloadsthat run on the Supervisor, includingvSphere Pods. In the “Considerations for Backing Up and Restoring Workload Management” table, the scenario “Backup and restore vSphere Pods” explicitly lists the required tool as“Velero Plugin for vSphere”, with the guidance to “Install and configure the plug-in on the Supervisor.”

The same document is explicit thatstandalone Velero with Restic is not valid for vSphere Pods, stating: “You cannot use Velero standalone with Restic to backup and restore vSphere Pods. You must use the Velero Plugin for vSphere installed on the Supervisor.”

vCenter file-based backup is documented for restoring theSupervisor control plane state, not for backing up and restoring vSphere Pod workloads themselves. Therefore, to meet the requirement to protect third-party applications running asvSphere Pods, the architect should propose theVelero Plugin for vSphere.

Answer (Correct Order):

Navigate in VCF Operations to Fleet Management → Tasks, select the instance and review Tasks

Check for errors or failed ClusterConfig objects

SSH into the Supervisor Cluster to review logs / attempt manual cleanup if required

Restart the WCP Service

To determinewhya Supervisor upgrade failed, you start where the platform records the most actionable failure context: themanagement-plane task history. The Fleet/Task view surfaces the upgrade workflow steps, timestamps, and the specific operation that failed, which gives you the fastest pointer to the failing phase (precheck, image staging, reconciliation, add-on updates, etc.). Next, you validate the Kubernetes-side reconciliation state by checking forfailed ClusterConfigobjects, because Supervisor enablement/upgrade actions commonly drive configuration via controller reconciliation; a failed ClusterConfig often contains the clearest “reason” and “message” fields that explain what blocked progress (validation errors, dependency issues, unreachable endpoints, incompatible components).

If the management-plane/task view and ClusterConfig status still don’t isolate the root cause, the next escalation is toSSH into the Supervisorto inspect component logs/events and identify low-level failures that may not bubble up cleanly (for example, admission failures, controller crashes, or connectivity/auth issues). Finally,restarting WCPis a remediation step that can clear stuck states, but it’s placed last because it can alter evidence and should not be your first action when you’re still trying to identify the original failure cause.

In the context of VMware Cloud Foundation (VCF) 9.0 and the vSphere Kubernetes Service (VKS), security and compliance are integrated into the cluster lifecycle. When deploying a Tanzu Kubernetes cluster through the vSphere Supervisor, setting the parameter ENABLE_AUDIT_LOGGING=true enables the Kubernetes API Server Audit logging feature. This functionality is essential for enterprise-grade observability and security forensics, as it provides a chronological record of all calls made to the Kubernetes API server.

When this setting is active, the API server records metadata about every request, including the identity of the user or service account making the call, the timestamp, the source IP address, the type of operation (e.g., create, update, delete), and the targeted resource. This data is critical for auditing administrative actions and identifying unauthorized or malicious activity within the cluster. While secondary tools like Fluent Bit (mentioned in Option B) may be used to forward these logs to an external destination such as VMware Aria Operations for Logs, the ENABLE_AUDIT_LOGGING flag is the specific configuration that triggers the generation of this audit trail at the source. In VCF 9.0, enabling audit logs is a standard recommendation for production environments to ensure that all changes to the declarative state of the Kubernetes infrastructure are transparent and traceable, meeting various regulatory and internal security requirements.

VCF 9.0 defines VKS as an upstream Kubernetes offering that isbuilt for vSphereand delivered with “well-thought-out defaults” to reduce operational burden. It states VKS provides an“opinionated installation of Kubernetes”with defaults “optimized for vSphere,” which “reduce[s] the amount of time and effort” typically spent deploying and running an enterprise Kubernetes cluster—this directly supportssimplified management and operations (A).

VCF 9.0 also emphasizes VKS is“integrated with the vSphere infrastructure”(storage, networking, authentication) and is built on a Supervisor that maps to vSphere clusters, creating a “unified product experience.” This supportsconsistent Kubernetes deployment on vSphere (B)because clusters are provisioned and operated in a standardized, vSphere-native way.

Finally, VCF 9.0 states VKS clusters “use open source Linux-based” components from VMware by Broadcom and notes key integrations (for example, CNI options) are open source—supportingleveraging open-source technologies (D).

OptionsCandEare not VKS benefits as stated: VKS targets VKS-provisioned upstream Kubernetes clusters (not “any distribution”), and “pods directly on ESXi” is described asvSphere Pods(Workload Management), not a defining benefit of VKS clusters.
