VMware Certified Advanced Professional - VMware Cloud Foundation 9.0 vSphere Kubernetes Service Advanced Practice Exam: Hard Questions 2025

A platform team runs vSphere Kubernetes Service (VKS) in a VMware Cloud Foundation environment. They observe intermittent pod-to-pod connectivity failures only for new pods scheduled on one ESXi host. Existing pods on that host continue to communicate normally. vCenter shows the host is connected and healthy, and the affected workloads span multiple namespaces. Which troubleshooting action most directly isolates whether the issue is in the vSphere Distributed Switch (VDS) dataplane used by VKS versus in Kubernetes (CNI/control-plane) state?

A customer requires strict multi-tenancy on a shared VKS platform. Tenants must not be able to see each other’s objects, must be prevented from escalating privileges to the host, and must not be able to consume unbounded vSphere resources through Kubernetes requests. Which design best satisfies these requirements with the least operational overhead while aligning with vSphere/Kubernetes boundaries?

An organization plans to deploy multiple VKS clusters for different application teams. They require deterministic IP management for pod and service networks across clusters, with no overlap, and need to integrate with an enterprise IPAM process. During cluster creation, what approach best prevents IP conflicts and supports long-term scalable operations?

After enabling VKS, a team attempts to create a new vSphere Namespace but Kubernetes workload deployment fails with errors indicating image pulls are blocked. Security policy requires all images to be pulled only from an internal registry that uses a custom CA. The internal registry is reachable from the workload network. What is the most correct configuration approach to satisfy the security requirement and resolve the image pull failures?

During VKS cluster provisioning, the supervisor-backed control plane comes up, but worker nodes fail to join. Logs indicate node bootstrap can reach the API endpoint, but kubelet registration times out and node leases are not being updated. DNS resolution is correct, and the load balancer for the API is healthy. Which network-level misconfiguration is the most likely root cause in this scenario?

A regulated environment requires that Kubernetes workloads running on VKS use persistent storage that is encrypted at rest and that encryption keys are managed externally with strict separation of duties. The storage team can provide a KMS and requires that vSphere enforce encryption, not an in-guest mechanism. Which design best meets the requirement?

A VKS cluster experiences frequent pod evictions during peak hours even though vSphere CPU and memory utilization appear below 60%. The Kubernetes events show eviction due to node pressure, and vSphere shows ballooning on some worker node VMs. The platform team wants to reduce evictions without overprovisioning the entire cluster. Which action is most appropriate?

An operations team enables cluster autoscaling for multiple VKS clusters. One cluster scales out repeatedly but performance does not improve; the new worker nodes show Ready, yet application pods remain Pending due to insufficient resources. vSphere shows the new worker node VMs are placed on a different vSphere cluster with a restrictive storage policy, causing PV provisioning failures and preventing scheduling for stateful workloads. Which governance control best prevents this class of issue at scale?

A tenant reports they can create Kubernetes objects in their vSphere Namespace, but attempts to create a LoadBalancer-type Service fail. The platform uses an external load balancer integration and requires per-tenant isolation with separate IP pools. Other tenants in different namespaces can create LoadBalancer Services successfully. Which is the most likely cause?

A security audit finds that developers in a tenant vSphere Namespace can deploy privileged pods with hostPath mounts, which violates policy. The team already uses Kubernetes RBAC to limit access, but developers still have enough rights to create Deployments. They need to enforce this restriction consistently across all namespaces while allowing exceptions for a controlled break-glass group. Which solution best meets the requirement?
