NEW QUESTION 24
Which kubectl command is used to list al pods in the current active namespace?

kubectl get nodes

kubectl get pods

kubectl get services

kubectl list pods

NEW QUESTION 25
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?

Manually update the CPU and memory of the nodes

Update the Virtual Machine Class Type

Increase the number of worker nodes

Increase the number of control plane nodes

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 26
Which two container network interfaces (CNIs) are supported with Tanzu Kubernetes clusters created by the Tanzu Kubernetes Grid Service? (Choose two )

NSX-T

Weave Net

Flannel

Antrea

Calico

https://docs.vmware.com/en/VMware-vSphere/7.0/vmware-vsphere-with-tanzu/GUID-A7756D67-0B95-447D-A645-E2A384BF8135.html A Tanzu Kubernetes cluster provisioned by the Tanzu Kubernetes Grid Service supports two CNI options: Antrea (default) and Calico. Both are open-source software that provide networking for cluster pods, services, and ingress.
Tanzu Kubernetes clusters provisioned by the Tanzu Kubernetes Grid Service support the following Container Network Interface (CNI) options:
Antrea
Calico
Explanation

Tanzu Kubernetes Grid Service CNI
Tanzu Kubernetes Grid Service supports Antrea and Calico as container network interfaces (CNI).
The default CNI in vSphere 7 Update 1 is Antrea.
Antrea is a VMware-supported, open source, Kubernetes-native project that implements the container network interface (CNI) and Kubernetes network policy, providing network connectivity and security for pod workloads. Antrea extends the benefit of programmable networks from Open vSwitch (OVS) to Kubernetes.
For more information about Antrea, see https://antrea.io/

NEW QUESTION 27
How does Kubernetes implement the vSphere storage policy in vSphere with Tanzu?

Storage class

Paravirtual CSl

Static Persistent Volume

Persistent Volume

NEW QUESTION 28
What is the proper way to delete a Persistent Volume Claim?

By using the kubectl delete persistentvolumeclaim command

By using the kubectl remove pvc command

Through the SPBM policy engine using the vSphere Client

By unmounting the volume from the VM and deleting it from the vSphere datastore

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.

NEW QUESTION 29
A development team has deployed a Tanzu Kubernetes cluster and would like to verify the version of Kubernetes that is running. Which command will show this information?

kubect1 describe tkc dev-cluster

kubect1 explain tkg dev-cluster

kubect1 get version

kubect1 get vm dev-cluster

NEW QUESTION 30
Which command will show the Tanzu Kubernetes cluster versions available in the vSphere content library?

kubect1 get rc,services

kubect1 get contentlibrary

kubect1 get tanzukubernetesreleases

kubect1 get tanzuimages

kubectl get tanzukubernetesreleases
List available Tanzu Kubernetes releases.
kubectl get tkr
Short form version of the preceding command.
kubectl get tkr v1.17.8—vmware.1-tkg.1.5417466 -o yaml
Provides details on the named Tanzu Kubernetes release.
VMware Tanzu distributes Kubernetes software versions as Tanzu Kubernetes releases. To consume these releases, you configure a vSphere Content Library and synchronize the available releases. You can do so using a subscription-based model, or on-demand. If you want to provision Tanzu Kubernetes in an internet restricted environment, you can create a local library and manually import the releases.

NEW QUESTION 31
Where are the virtual machine images stored that are used to deploy Tanzu Kubernetes clusters?

Content Library

Supervisor Cluster

Harbor Image Registry

Namespace

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 32
How do Tanzu Kubemetes clusters communicate with Storage Policy Based Management to request PersistentVolumes?

Through a proxy VM

Directly with vCenter Server and the underlying ESXi hosts

Through the Supervisor Cluster

Directlywith the vCenter Server

NEW QUESTION 33
Which two items must be provided before a vSphere with Tanzu Supervisor Namespace can be created?
(Choose two.)

vSphere with Tanzu Enabled Cluster

DNS-compliant Name

Permissions

Storage Policy

Resource Limits

NEW QUESTION 34
Which vSphere with Tanzu Workload Network topology provides Layer 2 isolation between Tanzu Kubernetes clusters across namespaces when vSphereDistributed Switches are used?

A dedicated Primary Workload Network for the Supervisor Cluster control plane VMs and separate Workload Networks for each namespace A dedicated Primary

Workload Network for the Supervisor Cluster control plane VMs and a single Workload Network for namespaces

A single Workload Network for the Supervisor Cluster control plane VMs and Tanzu Kubernetes clusters

Distributed firewall rules to isolate namespaces

NEW QUESTION 35
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)

NEW QUESTION 36
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

Explanation
Creating a Namespace
A vSphere administrator configures permissions and storage before a namespace can be used:
* Assign edit or view permissions to users. Users must be present in a configured single sign-on (SSO) identity source.
* Must assign a VM storage policy to the namespace.
* Can define resource limits (optional).
* Must add a content library to enable the Tanzu Kubernetes Grid Service.

NEW QUESTION 37
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>

NEW QUESTION 38
To which network are HA Proxy virtual server IP addresses issued when using the vSphere networking stack default configuration?

vMotion

Overlay

Primary workload

Management

The HAProxy virtual IP range where external services and DevOps users connect. In this configuration, HAProxy is deployed with two virtual NICs (Default configuration), one connected to the management network, and a second one connected to the Primary Workload Network. You must plan for allocating Virtual IPs on a separate subnet from the Primary Workload Network.
