On which cluster can a Supervisor Namespace be created?
- A. A Tanzu Kubernetes cluster
- B. A vSphere 7 cluster enabled with Workload Management
- C. A vSphere 6.7 cluster enabled with Workload Management
- D. A Tanzu Kubernetes Grid Integrated cluster
Answer: B
Explanation:
Explanation
A Supervisor Cluster namespace is a combination of resource allocations and permissions set within the Supervisor Cluster. When you create a Supervisor Namespace, you'll assign who has access to use it, and how many of the ESXi cluster's resources you can use (much like a resource pool).
When you enabled the Workload Management components, you created a special Kubernetes cluster called the
"Supervisor Cluster". You can continue to deploy virtual machines in this cluster, and you can also deploy kubernetes pods as a "pod vm" which is basically a container with some special wrapping so they are better isolated, like a virtual machine is.
NEW QUESTION # 70

NEW QUESTION # 79
How can you remove unreferenced container images from a project in an embedded Registry Service?
- A. Purge a namespace using the vSphere Client.
- B. Delete images in Content Library.
- C. Use kubectl to delete the images.
- D. Delete the namespace using the vSphere Client.
Answer: B
Explanation:
Deleting Artifact:
When an artifact is not referenced by any OCI index, you can delete the artifact freely which will delete its manifest and all associated tags.
When an artifact is referenced by an OCI index, you cannot delete it. In order to delete this artifact, you must first delete all OCI indexes referencing this artifact first, remembering that an artifact can be referenced by multiple parents artifacts pushed onto Harbor by different users. So when deleting an OCI index holding 9 children artifacts not referenced by any other index and 1 child artifact referenced by another index, only 9 out of 10 children artifacts will be deleted.
To delete any artifact in the Harbor interface, click on the artifact and select 'Delete' and confirm.
Not Purge: As a vSphere administrator, you can purge the images for a project in the private image registry by request from DevOps engineers. Purging images from the private image registry deletes all references to the images made by pods, but it does not remove the images from the image registry.

NEW QUESTION # 82
How can a vSphere administrator replace the Supervisor Cluster API endpoint certificate?
- A. Use the vSphere Client to replace the Workload platform MTG certificate.
- B. Use the certificate-manager CLI utility to replace the Supervisor Cluster API endpoint certificate.
- C. Use kubectl to replace the Supervisor Cluster API endpoint certificate.
- D. Use the vSphere Client to replace the NSX Load Balancer certificate.
Answer: A
Explanation:
As a vSphere administrator, you can replace the certificate for the virtual IP address (VIP) to securely connect to the Supervisor Cluster API endpoint with a certificate signed by a CA that your hosts already trust. The certificate authenticates the Kubernetes control plane to DevOps engineers, both during login and subsequent interactions with the Supervisor Cluster.
Prerequisites
Verify that you have access to a CA that can sign CSRs. For DevOps engineers, the CA must be installed on their system as a trusted root.
Procedure
In the vSphere Client, navigate to the Supervisor Cluster.
Click Configure then under Namespaces select Certificates.
In the Workload platform MTG pane, select Actions > Generate CSR.
Provide the details for the certificate.
Once the CSR is generated, click Copy.
Sign the certificate with a CA.
From the Workload platform MTG pane, select Actions > Replace Certificate.
Upload the signed certificate file and click Replace Certificate.
Validate the certificate on the IP address of the Kubernetes control plane.
NEW QUESTION # 83

- A. Choose the Kubernetes content library that should be used in the Supervisor Cluster
- B. Deploy the load balancer
- C. Define the Management network interfaces for the Supervisor Cluster
- D. Define the Primary workload network P range
Answer: C

As a vSphere administrator, you can enable the Workload Management platform on a vSphere cluster by configuring the vSphere networking stack to provide connectivity to workloads. A Supervisor Cluster that is configured with vSphere networking supports the deployment of Tanzu Kubernetes clusters created by using the Tanzu Kubernetes Grid Service. It does not support running vSphere Pod or using the embedded Harbor Registry.
NEW QUESTION # 86

NEW QUESTION # 87
Which statement describes a characteristic of Supervisor Cluster control plane VMs?
- A. Manage the lifecycle of ESXi hosts
- B. Host developer workloads
- C. Run system and infrastructure pods
- D. Are manually created by a vSphere administrator
Answer: C
Explanation:
The Supervisor Cluster provides the management layer on which Tanzu Kubernetes clusters are built. The Tanzu Kubernetes Grid Service is a custom controller manager with a set of controllers that is part of the Supervisor Cluster. The purpose of the Tanzu Kubernetes Grid Service is to provision Tanzu Kubernetes clusters.
While there is a one-to-one relationship between the Supervisor Cluster and the vSphere cluster, there is a one-to-many relationship between the Supervisor Cluster and Tanzu Kubernetes clusters. You can provision multiple Tanzu Kubernetes clusters within a single Supervisor Cluster. The workload management functionality provided by the Supervisor Cluster gives you control over the cluster configuration and lifecycle, while allowing you to maintain concurrency with upstream Kubernetes.
NEW QUESTION # 88
On which cluster can a Supervisor Namespace be created?
