A Cloud Administrator is troubleshooting a failed Tanzu Kubernetes Grid (TKG) cluster provisioning. The cluster creation task in the vSphere Client indicates a failure, but the error message is generic. The administrator decides to investigate the specific controller logs on the Supervisor.
Which specific Kubernetes object events should the administrator inspect using kubectl to find the most detailed error messages regarding the infrastructure provisioning (VM cloning, networking) of the TKG cluster nodes?
- A . kubectl get events –namespace kube-system
- B . kubectl logs deployment/wcp-auth-proxy
- C . kubectl describe tanzukubernetescluster
- D . kubectl describe virtualmachine

A VI Administrator attempts to upgrade the Supervisor Cluster but the option to upgrade is grayed out or unavailable in the vSphere Client, even though a new version is known to be available.
Which of the following are valid reasons for this state? (Select all that apply.)
- A . There are incompatible TKG clusters running on the Supervisor (e.g., a very old Kubernetes version that is deprecated in the target Supervisor release).
- B . The Supervisor Cluster is in a "Warning" or "Error" health state (e.g., invalid certificate, network partition).
- C . The vCenter Server itself has not been upgraded to a version that supports the new Supervisor release. (The Supervisor version cannot exceed the managing vCenter’s compatible version).
- D . The "License Service" is down.
- E . The ESXi hosts in the cluster are not running a compatible version (e.g., they are on an older build that doesn’t support the new Spherelet).

A Cloud Administrator is investigating a report that a newly provisioned TKG cluster dev-cluster-01 is stuck in the Provisioning phase. The developer reports that kubectl get nodes returns no results.
The administrator runs kubectl describe tanzukubernetescluster dev-cluster-01 and sees the following status condition:
Status:
Conditions:
– Last Transition Time:
"2023-11-20T14:30:00Z"
Message: "0/3
Control Plane Node(s) healthy. Error: vm-creation-failed"
Reason:
InfrastructureFailure
Status:
"False"
Type: Ready
The administrator then checks the VirtualMachine resource for one of the control plane nodes:
Status:
Conditions:
– Message: "Failed to deploy
VM: Resource pool ‘Namespaces’ has insufficient memory resources. Required:
16384 MB, Available: 4096 MB."
Reason:
ContentLibraryOvfDeployFailed
Status:
"True"
Type: Failure
Based on this data, what are the verified cause of the issue and the correct resolution? (Choose 2.)
- A . The cause is that the vSphere Namespace containing the cluster has a Memory Limit configured that is too low to support the reservations required by the Control Plane VMs.
- B . The resolution is to edit the TKG cluster YAML to use a smaller vmClass for the control plane nodes (e.g., best-effort-small instead of guaranteed-medium).
- C . The cause is that the ESXi hosts in the cluster are physically out of RAM.
- D . The resolution is to increase the Memory Limit on the vSphere Namespace via the vSphere Client.
- E . The cause is a corrupted OVF image in the Content Library.
All images must be scanned and hosted internally.
Which architectural components and configuration steps are strictly required to support this design? (Select all that apply.)
- A . Deploy a Private Container Registry (e.g., Harbor) within the air-gapped environment to host the system images (TKR) and package bundles.
- B . Configure the TkgServiceConfiguration (or global Supervisor settings) to trust the Private Registry’s CA certificate.
- C . Configure the TKG clusters to use a Private Package Repository CR that points to the internal registry URL instead of the default public VMware URL.
- D . Configure the Supervisor to use a HTTP Proxy to bypass the air-gap restrictions.
- E . Use an internet-connected machine to download/pull the required TKG images and Package Repository bundles from the public VMware registry, then push them to the internal Private Registry.

A DevOps Engineer attempts to deploy a database VM using the following YAML manifest, but the kubectl apply command results in the object staying in a pending state, and kubectl get virtualmachine shows a failure condition.
# postgres-vm.yaml
apiVersion: vmoperator.vmware.com/v1alpha1
kind: VirtualMachine
metadata:
name: pg-db-01
namespace: dev-playground
spec:
className: guaranteed-xlarge
imageName:
centos-8-stream-v10.ova
powerState: poweredOn
The VI Administrator checks the dev-playground namespace status:
nsx-cli> get namespace dev-playground
…
VM Service: Enabled
Assigned VM Classes:
– best-effort-small
– guaranteed-medium
Assigned Content Libraries:
– K8s-Images (Contains:
centos-8-stream-v10.ova)
…
What is the root cause of the provisioning failure?
- A . The powerState field is invalid; VMs are powered on by default.
- B . The imageName must include the full Content Library path (e.g., lib/K8s-Images/centos-8-stream-v10.ova).
- C . The VM Class guaranteed-xlarge requested in the YAML is not assigned to the dev-playground namespace.
- D . The VM Service is not compatible with CentOS 8 Stream images.
A Platform Engineer is designing a multi-zone Supervisor architecture to support a high-availability requirement for a critical financial application. The design involves three vSphere Zones: Zone-A, Zone-B, and Zone-C.
The engineer needs to create a vSphere Namespace fin-app-ns that can tolerate the failure of any single zone.
Review the following proposed configuration snippet for the Namespace creation:
# Proposed Namespace Configuration Logic
Name: fin-app-ns
Placement:
Zones:
– Zone-A
– Zone-B
Storage Policies:
– gold-storage-policy (assigned
to all zones)
Why is this proposed configuration insufficient to meet the "tolerate failure of any single zone" requirement for the Supervisor Control Plane and the workloads within this namespace? (Choose 2.)
- A . Kubernetes control planes typically require an odd number of members (e.g., 3) distributed across failure domains to maintain quorum (etcd) during a partition. Using only 2 zones risks split-brain scenarios.
- B . The configuration is actually valid; vSphere HA will handle the failover between Zone A and Zone
- C . C. vSphere Namespaces do not support multi-zone placement; they must be pinned to a single cluster.
- D . A 3-zone Supervisor deployment is required to support the Supervisor Control Plane’s high availability; restricting the Namespace to only two zones (A and B) prevents the Supervisor from placing control plane VMs in the third zone if one fails.
- E . The storage policy must be different for each zone to ensure replication.
