NEW QUESTION # 26
Which functionality does the Cloud Native Storage (CNS) component take advantage of to support the creation of container volumes?
- A. Storage Based Policy Management
- B. VMware Disk Encryption
- C. First Class Disk
- D. Virtual Disk
Answer: C
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.

How can a vSphere administrator replace the Supervisor Cluster API endpoint certificate?
- A. Use the vSphere Client to replace the NSX Load Balancer certificate.
- B. Use the vSphere Client to replace the Workload platform MTG certificate.
- C. Use the certificate-manager CLI utility to replace the Supervisor Cluster API endpoint certificate.
- D. Use kubectl to replace the Supervisor Cluster API endpoint certificate.
Answer: B
Explanation:
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 Replace Certificate.
* Upload the signed certificate file and click
* Validate the certificate on the IP address of the Kubernetes control plane.
NEW QUESTION # 31
How is the storage selected for the Harbor pods when the embedded Harbor image registry is enabled?
- A. vCenter Server automatically selects a local ESXi host datastore.
- B. vCenter Server automatically chooses a VM storage policy.
- C. An administrator selects a VM storage policy as part of enablement.
- D. An administrator selects a specific datastore as part of enablement.
Answer: C
Explanation:
Enabling Harbor Image Registry
The vSphere administrator uses the vSphere Client to enable Harbor. To enable this component, select a cluster, select Configure > Namespaces > Image Registry, and click ENABLE HARBOR:
* A VM Storage Policy is required to allocate storage for the Harbor pods.
* An IP Address, based on the ingress CIDR range, is allocated for the Harbor management interface.
* After a few minutes, Harbor is deployed and running. 184
NEW QUESTION # 32
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. Manually update the CPU and memory of the nodes
- D. Increase the number of worker nodes
Answer: A
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.

An administrator is planning the deployment of a vSphere with Tanzu using an NSX-T environment and must ensure that the control plane VMs and container images are placed onto different datastores. The administrator decides to create two datastores and apply differently named tags to each datastore.
Which additional action would the administrator need to perform to meet this requirement?

- B. Create two storage policies with different tag criteria and apply to the Supervisor Cluster using the vSphere Client.
- C. Create a single storage policy containing all tag criteria and apply to the Supervisor Cluster using the vSphere Client.

Answer: C
NEW QUESTION # 38
What is the proper way to delete a Persistent Volume Claim?
- A. By unmounting the volume from the VM and deleting it from the vSphere datastore
- B. By using the kubectl remove pvc command
- C. By using the kubectl delete persistentvolumeclaim command
- D. Through the SPBM policy engine using the vSphere Client
Answer: C
Explanation:
Also, kubectl delete pvc, which is much shorter.
DevOps engineers create persistent volume claims to request persistent storage resources. The request provisions a persistent volume object and a matching virtual disk. In the vSphere Client, the persistent volume claim manifests as an FCD virtual disk that can be monitored by vSphere administrators.
The claim is bound to the persistent volume. The workloads can use the claim to mount the persistent volumes and access storage.
When the DevOps engineers delete the claim, the corresponding persistent volume object and the provisioned virtual disk are also deleted.

Which statement describes a characteristic of Supervisor Cluster control plane VMs?
- A. Are manually created by a vSphere administrator
- B. Host developer workloads
- C. Manage the lifecycle of ESXi hosts
- D. Run system and infrastructure pods
Answer: D
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.
