Which component in the VKS architecture is responsible for providing the interface between the Kubernetes scheduler and the underlying vSphere storage capabilities, enabling dynamic provisioning of Persistent Volumes based on Storage Policy Based Management (SPBM)?
Show answer & explanation
Correct answer: D
The Container Storage Interface (CSI) Driver is the Kubernetes-side component that interfaces with the K8s scheduler and API server to handle storage requests. While CNS is the control plane component on vCenter, the CSI driver is what actually runs in the cluster to translate Kubernetes PVC requests into calls that CNS understands.

A platform engineer is reviewing the Helm chart deployment process for a VKS cluster. The team needs to ensure that specific configuration overrides are applied consistently across all deployments of the application. Which Helm concept should be utilized to manage these configuration parameters?
Show answer & explanation
Correct answer: A
In Helm, the
values.yamlfile is the standard method for defining default configuration parameters. These values can be overridden during installation or upgrade using--setflags or custom values files, ensuring consistent configuration management. - Question 3Intermediate
VMware Products and Solutions · Supervisor networking with VDS, NSX Segments, or VPCs
In a VCF 9.0 environment, an administrator is configuring the NSX Load Balancer for a Supervisor cluster that is expected to handle high throughput production traffic. What is the minimum required form factor for the NSX Edge nodes to support the Supervisor load balancing service?
Show answer & explanation
Correct answer: B
VCF 9.0 specifies the minimum NSX Edge cluster for a Supervisor as two Edge nodes of Large form factor in Active/Standby mode, each with 8 vCPU, 32 GB memory, and 200 GB storage, and the Edge deployment procedure says to select the Large form factor. The Edge cluster hosts the NSX load balancers for the Supervisor control plane, the namespaces, and published Services. Small and Medium are below the supported minimum, and Extra Large exceeds it without being required.

VMware Products and Solutions · Storage policies and persistent volume integration across zones
When configuring storage policies for a VKS deployment, which specific policy type is required to govern the placement of the ephemeral disks used by vSphere Pods?
Show answer & explanation
Correct answer: D
vSphere Pods require a specific storage policy assignment for their ephemeral disks (the disks that hold the container filesystem and logs). This is distinct from the policies used for persistent volumes or the image cache.
- Question 5Advanced
VMware Products and Solutions · Manage Kubernetes releases and content libraries (subscribed, local, and air-gapped) for VKS clusters
A security engineer needs to configure a VKS cluster in an air-gapped environment where no internet access is available. To successfully provision Kubernetes clusters, which configuration is mandatory regarding the Tanzu Kubernetes Release (TKR) images?
Show answer & explanation
Correct answer: C
In an air-gapped environment, the vCenter Server cannot reach the external VMware repository. The administrator must download the TKR OVF templates from a connected machine and upload them to a Local Content Library on the vCenter Server to make them available for cluster provisioning.
- Question 6Beginner
VMware Products and Solutions · Configure CNIs, NSX networking objects, and TLS certificates and secure VKS clusters
Which CNI plugin is the default and integrated networking solution for VKS clusters in VCF 9.0, providing both pod networking and security policy enforcement?
Show answer & explanation
Correct answer: C
Antrea is the default Container Network Interface (CNI) plugin for VKS clusters in VCF 9.0. It is an open-source Kubernetes networking solution based on Open vSwitch, providing high performance and integrated security policies.
