NO.28 Which external load balancer is supported in vSphere 7 U1 using the vSphere networking stack?

Nginx

Seesaw

Loadmaster

HAProxy

When using vSphere with Tanzu with vDS networking, HAProxy provides load balancing for developers accessing the Tanzu Kubernetes control plane, and for Kubernetes Services of Type Load Balancer. Review the possible topologies that you can implement for the HAProxy load balancer.
https://docs.vmware.com/en/VMware-vSphere/7.0/vmware-vsphere-with-tanzu/GUID-1F885AAE-92FF-41E6-BF04-0F0FD4173BD9.html The HAProxy appliance is an open-source solution developed by HAProxy Technologies and chosen by VMware as the first supported open-source load balancer for use with vSphere with Tanzu. With the HAProxy, external network traffic is routed to Kubernetes pods running in the vSphere with Tanzu environment.

NO.29 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 )

Whether the resources provided by the virtual machine class type should be reserved on the host

The configuration parameters which need to be edited in the cluster

The amount of CPU. memory, and storage the virtual machine should have

Connectivity between the Tanzu Kubernetes cluster and the Subscribed Content Library

The storage classes which need to be made available to the cluster

NO.30 Which object helps maintain copies of a vSphere pod?

ReplicaSets

Network Policies

Namespaces

Persistent Volume

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.
For more information about Kubernetes replica sets, see https://kubernetes.io/docs/concepts/workloads/controllers/replicaset/

NO.31 Which three roles does the Spherelet perform? (Choose three )

Determines placement of vSphere pods

Manages node configuration

Starts vSphere pods

Provides a key-value store for pod configuration

Communicates with Kubernetes API

Provisions Tanzu Kubernetes clusters

NO.32 How can you remove unreferenced container images from a project in an embedded Registry Service?

Delete images in Content Library.

Use kubectl to delete the images.

Delete the namespace using the vSphere Client.

Purge a namespace using the vSphere Client.

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.

NO.33 What is the minimum number of virtual distributed portgroups that must be configured on the vSphere Distributed Switch before enabling Workload Management using the vSphere networking stack and a HAProxyload balancer?

NO.34 Which three elements should be configured by a vSphere administrator after creating vSphere Namespace?
(Choose three.)

Permissions

Capacity and Usage limits

License

Namespace name

Storage Policy

NSX Segment

NO.35 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?

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

Four IP addresses are required, one for each of the Control Plane VMs and one spare for performing rolling cluster upgrades

Three IP addresses are required, one for each of the Control Plane VMs

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.

Static IPs for Kubernetes control plane VMs
Block of 5A block of 5 consecutive static IP addresses to be assigned to the Kubernetes control plane VMs in the Supervisor Cluster.

NO.36 On which cluster can a Supervisor Namespace be created?

A Tanzu Kubernetes Grid Integrated cluster

A vSphere 7 cluster enabled with Workload Management

A Tanzu Kubernetes cluster

A vSphere 6.7 cluster enabled with Workload Management

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.

NO.37 The virtualization team supports many development teams on a Supervisor cluster. For a specific development team, they would like to limit persistent volumes that can be created on Tanzu Kubernetes clusters to only an NFS based storage array.
Which action should be taken to accomplish this goal?

Use kubectl to create a storage class in the Supervisor cluster.

Set a resource quota limiting the number of PVCs for that development team.

Add a storage policy to that development team’s Supervisor Namespace containing only the NFS datastore

Disconnect non-NFS datastores from the ESXi hosts that make up the Supervisor cluster.

NO.38 Which is a valid version change for a Tanzu Kubernetes cluster running Kubernetes version 1.16.7?

Upgrade one major version (e.g.. 2.0.1)

Upgrade two minor versions (e.g., 1.18.0)

Downgrade one patch version (e.g.. 1.16.5)

Upgrade one minor version (e.g.. 1.17.0)

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.

NO.39 Which command provides valid syntax to deploy a vSphere Pod?

tkg apply -c containerName

docker run containerName

kubectl apply -f deployment.yaml

kubectl apply -t deployment.yaml

You can deploy an application on a namespace on a Supervisor Cluster. Once the application is deployed, the respective number of vSphere Pods are created on the Supervisor Cluster within the namespace.
Common kubectl commands include the apply, get, describe, and delete commands:
* The kubectl apply command applies the contents of a YAML file. Typically, this command is used to create a pod or deployment: – kubectl apply -f /path/to/my.yaml
* The kubectl get command returns basic information about an object: – kubectl get pod <pod_name_name>
