NEW QUESTION # 18
Which vSphere with Tanzu Workload Network topology provides Layer 2 isolation between Tanzu Kubernetes clusters across namespaces when vSphere Distributed Switches are used?
- A. A single Workload Network for the Supervisor Cluster control plane VMs and Tanzu Kubernetes clusters
- B. Distributed firewall rules to isolate namespaces
- C. Workload Network for the Supervisor Cluster control plane VMs and a single Workload Network for namespaces
- D. A dedicated Primary Workload Network for the Supervisor Cluster control plane VMs and separate Workload Networks for each namespace A dedicated Primary
Answer: D
Explanation:
Explanation
For a Supervisor Cluster that is configured with the vSphere networking stack, you can provide Layer 2 isolation for your Kubernetes workloads by creating Workload Networks and assigning them to namespaces.
Workload Networks provide connectivity to Tanzu Kubernetes clusters in the namespace and are backed by distributed port groups on the switch that is connected to the hosts in the Supervisor Cluster.
NEW QUESTION # 19
Which is a valid version change for a Tanzu Kubernetes cluster running Kubernetes version 1.16.7?
- A. Upgrade two minor versions (e.g., 1.18.0)
- B. Upgrade one major version (e.g.. 2.0.1)
- C. Downgrade one patch version (e.g.. 1.16.5)
- D. Upgrade one minor version (e.g.. 1.17.0)
Answer: D
Explanation:
Be aware of the following constraints when upgrading your cluster.
You can upgrade a cluster up to one minor version of Kubernetes from its current version. If necessary, you can perform subsequent upgrades to move the version forward.
Upgrading your version of Kubernetes is a one-way operation. You cannot subsequently downgrade the Kubernetes version, or undo an upgrade.
NEW QUESTION # 20

- D. Set a CPU reservation on the Namespace Resource Pool in vCenter.
Answer: A
NEW QUESTION # 22
Which description reflects a use case for an embedded image registry?

Answer: B
NEW QUESTION # 23
An administrator needs to get a list of all Tanzu Kubernetes clusters running in the current namespace.
Which command will provide the desired output?
- A. kubectl get vmservice
- B. kubectl get virtualnetwork
- C. kubectl get tanzukubernetescluster
- D. kubectl get clusters
Answer: D
NEW QUESTION # 24
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 the namespace using the vSphere Client.
- C. Use kubectl to delete the images.
- D. Delete images in Content Library.
Answer: D
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 # 25
An organization is preparing to deploy vSphere with Tanzu and will be using the vSphere Networking stack.
How should the administrator allocate management network IP addresses for the Kubernetes Control Plane within the Supervisor Cluster?
- A. Five IP addresses are required, one for each of the Control Plane VMs. one for the floating IP address of the Control Plane VM, and one spare for performing rolling cluster upgrades
- B. Three P addresses are required, one for each of the Control Plane VMs
- C. Six IP addresses are required, one for each of the Control Plane VMs, one for the floating IP address of the Control Plane VM. one for performing rolling cluster upgrades and one for the image Registry VM.
- D. Four f3 addresses are required, one for each of the Control Plane VMs and one spare for performing rolling cluster upgrades
Answer: A
NEW QUESTION # 26
Which object helps maintain copies of a vSphere pod?
- A. Network Policies
- B. Persistent Volume
- C. Namespaces
- D. ReplicaSets
Answer: D
Explanation:
A ReplicaSet declares how the functionality of a pod is made scalable and resilient through redundancy. The ReplicaSet ensures that a specified number of pods is kept running. Example: Deploy a ReplicaSet. * The ReplicaSet name is nginx-replica-demo. * Two replicas are expected to be running. * The ReplicaSet applies to pods with label nginx.

NEW QUESTION # 28
How does Kubernetes implement the vSphere storage policy in vSphere with Tanzu?
- A. Persistent Volume
- B. Paravirtual CSl
- C. Storage class
- D. Static Persistent Volume
Answer: C
Explanation:
Explanation
When vSphere with Tanzu converts storage policies that you assign to namespaces into Kubernetes storage classes, it changes all upper case letters into lower case and replaces spaces with dashes (-). To avoid confusion, use lower case and no spaces in the VM storage policy names.
Storage Policy Based Management is a vCenter Server service that supports provisioning of persistent volumes and their backing virtual disks according to storage requirements described in a storage policy.
NEW QUESTION # 29
Which step is necessary in order to allocate storage to a newly created namespace?

- B. Assign permissions to users
- C. Add a content library
- D. Define resource limits
Answer: A
