An administrator is tasked with increasing the amount of CPU and memory in an existing Tanzu Kubernetes cluster.
Which change must the administrator complete to ensure the cluster scales successfully when updating the YAML definition?
- A. Update the Virtual Machine Class Type
- B. Increase the number of control plane nodes
- C. Increase the number of worker nodes
- D. Manually update the CPU and memory of the nodes
Answer: A
Explanation:
Explanation
Virtual Machine Class Types for Tanzu Kubernetes Clusters
A virtual machine class defines the resource sizing for Tanzu Kubernetes cluster VMs: * CPU * Memory * Storage Virtual machine class types range from extra small (xsmall) to extra large (xlarge). Class types are categorized as guaranteed or best effort:
* Guaranteed: Reserve all CPU and memory allocations. * Best effort: Allocate the same CPU and memory but do not reserve the resources.
The class type guaranteed-small allocates 2 CPU, 4 GB of memory, and 16 GB of storage and reserves CPU and memory allocations. Custom virtual machine class types cannot be defined.

NEW QUESTION # 68
Where are the virtual machine images stored that are used to deploy Tanzu Kubernetes clusters?
- A. Harbor Image Registry
- B. Content Library
- C. Supervisor Cluster
- D. Namespace
Answer: B
Explanation:
The vSphere administrator configures a Subscribed Content Library on the Supervisor Cluster. The virtual machine image that is used for the Tanzu Kubernetes cluster nodes is pulled from this library. A Subscribed Content Library originates from a Published Content Library. After the subscription is created, the system synchronizes it with the published library. To create the Tanzu Kubernetes cluster nodes, VMware publishes a Photon OS OVA library to which you subscribe. After the subscriber is synchronized with the publisher, you associate the content library with the Supervisor Cluster.

NEW QUESTION # 70
Which functionality does the Cloud Native Storage (CNS) component take advantage of to support the creation of container volumes?
- A. First Class Disk
- B. Virtual Disk
- C. VMware Disk Encryption
- D. Storage Based Policy Management
Answer: A
Explanation:
Explanation
The Cloud Native Storage server resides in vCenter Server:
* Provisions and manages life cycle operations for container volumes
* Creates First Class Disks (FCDs) to support the container volumes
* First Class Disks exist as .vmdk and -flat.vmdk files on a vSphere datastore * Integrates with storage policy based management (SPBM) for the placement of disks A First Class Disk (FCD) is also called an improved virtual disk. It is a named virtual disk that is unassociated with a VM. These disks reside on a VMFS, NFS, or vSAN datastore and support container volumes.
Storage policy based management (SPBM) is a vCenter Server service that supports provisioning of persistent volumes according to specified storage requirements. After provisioning, the service monitors compliance of the volume with the required policy characteristics.
NEW QUESTION # 71
What is the proper way to delete a Persistent Volume Claim?
- A. Through the SPBM policy engine using the vSphere Client
- B. By using the kubectl delete persistentvolumeclaim command
- C. By using the kubectl remove pvc command
- D. By unmounting the volume from the VM and deleting it from the vSphere datastore
Answer: B
NEW QUESTION # 72
What needs to be deployed to access applications on vSphere with Tanzu?
- A. Virtual router
- B. External load balancer
- C. vSphere Distributed Switch
- D. Internal load balancer
Answer: B
NEW QUESTION # 73
How can you remove unreferenced container images from a project in an embedded Registry Service?
- A. Delete the namespace using the vSphere Client.
- B. Delete images in Content Library.
- C. Purge a namespace using the vSphere Client.
- D. Use kubectl to delete the images.
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 # 74

NEW QUESTION # 77
Which two considerations needs to be made when deciding on a virtual machine class type during the process of creating a Tanzu Kubernetes cluster? (Choose two )
- A. Whether the resources provided by the virtual machine class type should be reserved on the host
- B. The storage classes which need to be made available to the cluster
- C. The configuration parameters which need to be edited in the cluster
- D. The amount of CPU. memory, and storage the virtual machine should have
- E. Connectivity between the Tanzu Kubernetes cluster and the Subscribed Content Library
Answer: A,D
Explanation:
A virtual machine class is a request for resource reservations for processing power on the virtual machine (VM), including CPU and memory (RAM). For example, the VM class type named "guaranteed-large" reserves 4 CPU and 16 GB RAM. See Default Virtual Machine Classes for a list of default VM classes and their corresponding CPU and RAM reservations.
The VM disk size is set by the OVA template, not the VM class definition. For Tanzu Kubernetes releases, the disk size is 16GB. See About Tanzu Kubernetes release Distributions.
There are two reservation types for VM classes: guaranteed and best effort. The guaranteed class fully reserves its configured resources. This means that for a given cluster the spec.policies.resources.requests matches the spec.hardware settings. The best effort class allows resources to be overcommitted. For production workloads it is recommended that you use the guaranteed VM class type.
NEW QUESTION # 78
Which role should the vSphere administrator apply for the developer?
- A. Assign the developer user with the 'VSphere Kubernetes Manager" role at the cluster object.
- B. Assign the developer user with the "can edit" role at the cluster object.
- C. Assign the developer user with the "can edit" role at the vSphere Namespace object.
- D. Assign the developer user with the 'VSphere Kubernetes Manager" role at the vSphere Namespace object.
Answer: C
Explanation:
Permissions for programmers should be assign at the Namespace level, typically using groups and roles.
You assign roles for the Namespace to Active Directory groups. You can later assign access to users by adding them to these groups. You assign access to separate Active Directory groups for the edit and view roles in the Namespace.
