Q21. A Platform Engineer is attempting to upgrade a TKG cluster dev-cluster to Kubernetes version v1.24.9. However, the upgrade validation fails with the error Image not found.
The engineer checks the available versions in the namespace:
$ kubectl get tkr
NAME VERSION COMPATIBLE
v1.22.9—vmware.1-tkg.1 v1.22.9+vmware.1 True
v1.23.8—vmware.1-tkg.1 v1.23.8+vmware.1 True
The VI Administrator checks the Content Library Tanzu-Lib in vCenter and confirms that the OVF template for v1.24.9 is present and synced.
What is the most likely reason the TKG cluster cannot see the new version? (Choose 2.)

The new TKR version (v1.24.9) is not compatible with the current version of the Supervisor Cluster (Control Plane).

The TKG cluster is paused.

The Content Library Tanzu-Lib has not been assigned/added to the dev-namespace where the cluster resides.

The TKR object for v1.24.9 has not yet reconciled or been generated by the Supervisor because the Content Library synchronization is incomplete or corrupt for that specific item.

The developer needs to update their kubectl client version first.

Q22. A VI Administrator needs to configure a new vSphere Namespace called dev-team-a to ensure it uses a specific storage profile for persistent volumes.
Review the following configuration view:
Namespace: dev-team-a
Status: Active
Description: Development Team A Environment
[Resource Limits]
CPU: Unlimited
Memory: Unlimited
Storage: [Add Storage Policy…]
Which action must the administrator take to allow Kubernetes workloads in this namespace to provision persistent volumes using the gold-storage policy?

Create a new Storage Class in Kubernetes referencing gold-storage and apply it to the namespace via kubectl.

Edit the Namespace in the vSphere Client and add the gold-storage policy to the “Storage Policies” card.

Tag the datastores associated with gold-storage with the tag namespace:dev-team-a.

Configure the gold-storage policy on the Supervisor Cluster object directly.

Q23. An administrator is tasked with enabling a Supervisor cluster in VMware Cloud Foundation (VCF).
Arrange the steps below In the correct order to complete the process of enabling a Supervisor In the environment.

Q24. What three controllers maintain the lifecycle of VMware vSphere Kubernetes Service (VKS) clusters?
(Choose three.)

Container Network Interface

Virtual Machine Service

Cloud Provider Plug-in

Container Storage Interface

Cluster API

Q25. An administrator is building a secure, multi-tenant container registry strategy for their vSphere Kubernetes Services deployment running on VMware Cloud Foundation. Each workload domain hosts a Supervisor Cluster, and multiple development teams require private repositories to store and distribute container images for Kubernetes clusters. The organization enforces strict image security posture due to compliance requirements. The operations team deploys Harbor as an add-on service through the Supervisor control plane, and developers push/pull images from Harbor through Kubernetes manifests.
What requirement describes the role and purpose of Harbor?

Harbor, formerly known as Bitnami, is an image catalog used for downloading verified open-source packages.

Harbor is an image scanner used to verify that images are free from known vulnerabilities and patches as necessary.

Harbor is an open-source registry that secures artifacts with policies and role-based access control, ensures images are scanned and free from vulnerabilities, and signs images as trusted.

Harbor is an image repository that pulls all images from GitHub.

Q26. A Cloud Administrator receives a request to deploy a Supervisor Cluster that supports NSX Segments for namespaces. This allows developers to create their own logical segments within their namespace using kubectl.
Scenario:
* VCF environment with NSX-T.
* Supervisor is not yet enabled.
* The requirement is to allow Namespace-1 to have a segment 192.168.10.0/24 and Namespace-2 to have 192.168.20.0/24, both routable.
Which design choices are valid for this configuration? (Choose 2.)

Developers will create a VirtualNetwork (or similar CRD depending on version) object in their namespace to trigger the segment creation.

This requires the VDS networking stack with HAProxy, as NSX enforces a flat overlay.

The administrator must manually create each Logical Switch in NSX Manager and map it to the Namespace.

The Supervisor must be enabled with the NSX networking stack.

The administrator defines a Network Policy in the Supervisor context that allocates a block of IPs (e.g., /16) to the cluster, from which NSX will carve out /24 segments for each Namespace automatically or upon request.

Q27. A VI Administrator sees that a new version of the Harbor Supervisor Service (v2.5.0) is available in the vSphere Client “Services” inventory. The current installed version on the Supervisor Cluster Sup-Cluster-
01 is v2.4.0.
What is the correct procedure to upgrade the running Harbor service instance to the new version?
(Choose 2.)

Run kubectl set image deployment/harbor-core image=harbor:v2.5.0 directly on the Supervisor.

Download the new Service Definition (YAML/OVS) from the VMware Marketplace and update the existing Service Definition in vCenter.

In the vSphere Client, navigate to Workload Management > Services > Installed Services, select the Harbor instance, and click Upgrade Available (or “Update”).

Upgrading Supervisor Services requires upgrading the entire vCenter Server first.

Uninstall the v2.4.0 service and then install v2.5.0.

Q28. A Platform Engineer observes that a TKG cluster upgrade has failed with the status Condition:
Incompatible. The error message indicates that the VirtualMachineClass referenced in the cluster YAML (guaranteed-large-v1) is no longer available in the namespace.
The administrator realizes that the guaranteed-large-v1 class was recently removed from the Namespace configuration in favor of guaranteed-large-v2.
How should the engineer recover the cluster and complete the upgrade? (Select all that apply.)

Once the manifest is updated to guaranteed-large-v2, the Supervisor will trigger a rolling update to replace the nodes with the new class (and new version if specified).

Add the guaranteed-large-v1 class back to the Namespace in the vSphere Client to satisfy the current state requirements, allowing the controller to reconcile the current state before moving to the new state.

Edit the TanzuKubernetesCluster manifest to update the vmClass field to guaranteed-large-v2 for the node pools.

Manually rename the VM Class in vCenter from guaranteed-large-v2 to guaranteed-large-v1.

The cluster must be deleted and recreated because the VM Class is immutable once provisioned.

Q29. A Platform Engineer is designing an auto-scaling strategy for a cluster hosting a machine learning workload. The workload creates transient “Job” pods that require significant GPU resources.
Requirements:
1. The cluster usually runs with 2 worker nodes.
2. When a ML job starts, it might request 10+ pods, each needing a full GPU.
3. The cluster must scale up to satisfy these requests and scale down to 0 or 2 when idle to save costs.
4. There is a limited number of GPU-capable hosts in the vSphere cluster.
Which design considerations are critical for the correct functioning of the Cluster Autoscaler in this scenario? (Choose 2.)

The Cluster Autoscaler must be configured to ignore GPU resource requests because vSphere handles GPU assignment via DRS.

The vSphere Namespace must have a resource quota that allows for the maximum potential CPU/Memory/GPU usage of the scaled-out cluster (e.g., sufficient for 12+ nodes).

The TanzuKubernetesCluster YAML must define a separate worker node pool specifically using a GPU-enabled VM Class (e.g., gpu-large).

The min-size for the GPU node pool should be set to 0 (Zero) to allow scaling from zero, assuming the VKS version supports scale-from-zero behavior.

The workload Pods must use podAntiAffinity to ensure they are scheduled on the Control Plane nodes.

Q30. The DevOps Engineer was tasked to deploy a new application on a local cluster. When the application was deployed in the Namespace, it was decided that a newer version of Kubernetes was required. The DevOps Engineer requested the vSphere Admin to upgrade their Kubernetes version. The vSphere Admin checked compatibility between the Supervisor and all running VKS clusters, and then successfully upgraded vSphere Supervisor to the latest version. The DevOps Engineer could not get the application to work. What caused the application to fail?

The vSphere Admin failed to complete all the pre-checks before the upgrade.

The vSphere Admin pulled down the wrong version of the Supervisor.

The vSphere Admin did everything correctly and the DevOps Engineer is deploying the application wrong.

The vSphere Admin upgraded the Supervisor Control Plane.

Q31. A DevOps Engineer is planning the deployment of a new microservices application. One specific service, Service-A, has a strict requirement to load a custom, proprietary Linux kernel module (.ko) to function correctly.
Which compute model must the engineer select for Service-A within vSphere with Tanzu?

Tanzu Kubernetes Grid (TKG) Cluster Nodes

Supervisor Control Plane VMs

Static Pods on the ESXi host

vSphere Pods

Q32. An administrator is upgrading an existing VMware vSphere Kubernetes Service (VKS) cluster and receives the following errors:
kubectl get nodes fails with memcache.go and “server is currently unable to handle the request” couldn’t get resource list for stats.antrea.tanzu.vmware.com/v1alpha1 yaml: mapping values are not allowed in this context The administrator successfully updated the Supervisor, but an attempt to update the VKS cluster failed. Based on the scenario, what is the cause of the problem?

The administrator is in the wrong cluster context.

The Kubernetes version being upgraded is no longer supported.

There was an error pulling the update image from the catalog.

The administrator does not have the appropriate permissions to upgrade the cluster.

Q33. In the context of vSphere with Tanzu architecture using NSX networking, what is the primary function of the SNAT (Source Network Address Translation) rule configured for a vSphere Namespace?

It encrypts traffic leaving the namespace to ensure secure communication between different vSphere Zones.

It maps the internal IP addresses of Pods and TKG cluster nodes within the namespace to a routable IP from the Egress IP CIDR, allowing them to initiate outbound connections to external networks.

It provides a static, dedicated public IP address for every individual Pod in the namespace to be reachable from the internet (1:1 NAT).

It balances incoming traffic from the external network across multiple replicas of a Kubernetes Service (Load Balancing).

Q34. The vSphere Admin creates a vSphere Namespace harbor-project and grants the DevOps Engineer edit permissions. The DevOps Engineer deploys the Harbor service in thisnamespace with the command: kubectl apply -f harbor-svc.yml The Harbor service deploys successfully, but the database data harbor database 0 pods does not come into a Running state.
Click the two locations where the administrator should verify the Access Modes forthis pod ‘ s PerslstentVolumeClaim (PVC). (Choose two.)

Q35. An architect is meeting with a customer to deploy a mission-critical application using the vSphere Kubernetes Service. The architect learns that the ticketing application runs at a steady state 80% of the time but has significant spikes when an event is announced. The application is unable to meet demand even though resources are available.
What will address the issue of peak demand?

Install cluster autoscaling.

Enable Foundation Load Balancer to manage the network traffic during peak demand.

Oversubscribe the vSphere Kubernetes environment so that adequate resources are always available.

Install the Contour Supervisor Services package.

Q36. Which protocols are supported for use as an external identity provider for VMware vSphere Kubernetes Service (VKS) clusters?

OpenID Connect (OIDC)

System for Cross-Domain Identity Management (SCIM)

Security Assertion Markup Language (SAML 2.0)

Active Directory over LDAP

Q37. A Platform Engineer attempts to create a snapshot of a PVC named mysql-data but the VolumeSnapshot object remains in a ReadyToUse: False state.
The engineer inspects the status:
$ kubectl describe volumesnapshot mysql-snap
…
Status:
Ready To Use: false
Error: Snapshot creation failed: Error: CNS: CnsVolumeNotFound
What is the most likely cause of this error? (Choose 2.)

The PVC mysql-data is currently mounted by a running Pod, and the vSphere CSI driver (in certain versions/configurations) or the specific filesystem requires the volume to be quiesced or unmounted (or the FCD ID is missing/mismatched).

The virtual disk (VMDK) associated with the PV was manually moved to a different datastore using Storage vMotion without updating the CNS metadata.

The Namespace quota for snapshots has been exceeded.

The VolumeSnapshotClass specified does not exist.

The underlying Persistent Volume (PV) backing the PVC mysql-data has been deleted or detached from the CNS (Cloud Native Storage) perspective in vSphere.

Q38. Which type of storage is used by VMware vSphere Kubernetes Service (VKS) pods to store non-persistent data?

Container image storage

Ephemeral storage

Object storage

vSphere local storage

Q39. An administrator is tasked with enabling a Supervisor cluster in VMware Cloud Foundation (VCF).
Arrange the steps below In the correct order to complete the process of enabling a Supervisor In the environment.

Q40. A Cloud Administrator is troubleshooting connectivity issues for a vSphere Namespace named finance-prod. Workloads within this namespace are unable to connect to an external Oracle database located at 10.50.1.200.
Review the following NSX Logical Router configuration output for the Tier-1 Gateway associated with the namespace:
nsx-cli> get logical-router interface
…
Interface : 928374-uuid-downlink
Type : downlink
IP/Mask : 10.244.0.1/28 (Pod CIDR Gateway)
…
nsx-cli> get nat rules
…
Rule ID : 1001
Action : SNAT
Source : 10.244.0.0/28
Translated : 192.168.100.5
Status : Enabled
…
# External Firewall Logs (Corporate Firewall)
Drop: Src 192.168.100.5 Dst 10.50.1.200 Proto TCP Port 1521 (Rule: Default Deny) Based on the data, what is the root cause of the connectivity failure? (Choose 2.)

The destination Oracle database is down.

The SNAT rule is disabled in NSX.

The Corporate Firewall is blocking traffic based on the translated Source IP (the Egress IP), not the internal Pod IP.

The SNAT IP 192.168.100.5 assigned to the namespace egress traffic is not whitelisted on the external Corporate Firewall.

The Pod CIDR 10.244.0.0/28 is exhausted, preventing the workload from acquiring an IP to initiate the connection.

Q41. A VKS Administrator manages a fleet of TKG clusters running the tanzu-standard package repository version v1.6.0. A critical CVE has been identified in the installed version of Fluent Bit, which is resolved in package repository version v2.0.0.
What is the correct procedure to update the available packages on a target cluster to the new version?
(Choose 2.)

Manually uninstall the old Fluent Bit package and reinstall it using helm install from a local chart.

Delete the PackageRepository object and recreate it with the same name but the new URL; this will automatically upgrade all installed packages immediately.

Update the vSphere Supervisor version; package repositories are immutable and tied strictly to the Supervisor release.

Use kubectl to update the PackageRepository CR named tanzu-standard in the cluster, changing the spec.fetch.imgpkgBundle.image tag to the new version (v2.0.0).

Wait for the kapp-controller to reconcile the change. Once the repository status is ReconcileSucceeded, the new package versions (e.g., Fluent Bit 2.x) will be listed in kubectl get packages.

Q42. A Platform Engineer needs to deploy the Contour Ingress Controller on a TKG cluster to manage Layer 7 routing for multiple microservices. The engineer wants to manage this installation as a standard Tanzu Package.
Review the following command sequence intended for the installation:
tanzu package available list standard.tanzu.vmware.com
tanzu package install contour
–package-name contour.tanzu.vmware.com
–version 1.20.2+vmware.1-tkg.1
–values-file contour-values.yaml
What is the primary role of the –values-file (contour-values.yaml) in this deployment model?

It contains the TLS certificates for the applications that will be exposed by Contour.

It provides the credentials for the private registry where the Contour images are stored.

It customizes the default configuration of the Contour package, allowing the engineer to specify settings like the LoadBalancer service type (e.g., NodePort vs LoadBalancer), Envoy replica counts, and internal/external visibility.

It defines the list of Ingress resources (routes) that Contour should create immediately upon installation.
