NEW QUESTION # 40
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 certificate-manager CLI utility to replace the Supervisor Cluster API endpoint certificate.
- C. Use the vSphere Client to replace the Workload platform MTG certificate.
- D. Use kubectl to replace the Supervisor Cluster API endpoint certificate.
Answer: C
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 pane, select Actions > Replace Certificate.
Upload the signed certificate file and click Replace Certificate.
Validate the certificate on the IP address of the Kubernetes control plane.
NEW QUESTION # 41 
Which capability do persistent volumes provide to containerized applications?
- A. Retention of application state and data
- B. Automated disk archival
- C. Support for in-memory databases
- D. Support for ephemeral workloads
Answer: A
Explanation:
Explanation
Certain Kubernetes workloads require persistent storage to store data permanently. To provision persistent storage for Kubernetes workloads, vSphere with Tanzu integrates with Cloud Native Storage (CNS), a vCenter Server component that manages persistent volumes.
Persistent storage is used by vSphere Pods, Tanzu Kubernetes clusters, and VMs. The following example illustrates how persistent storage is used by a vSphere Pod.
vSphere Pods use different types of storage depending on the objects that are stored. The types of storage are ephemeral virtual machine disks (VMDKs), persistent volume VMDKs, and containers image VMDKs:
* Storage policies for container image and ephemeral disks are defined at the cluster level.
* Storage policies for persistent volumes are defined at the namespace level.
* Networking for vSphere Pods uses the topology provided by NSX.
NEW QUESTION # 42
Which three roles does the Spherelet perform? (Choose three )
- A. Starts vSphere pods
- B. Provisions Tanzu Kubernetes clusters
- C. Communicates with Kubernetes API
- D. Determines placement of vSphere pods
- E. Manages node configuration
- F. Provides a key-value store for pod configuration
Answer: A,C,E
Explanation:
Explanation
Spherelet is a kubelet that is ported natively to ESXi. It allows the ESXi host to become part of a Kubernetes cluster. Spherelet performs the following functions:
* Communicates with the control plane VMs
* Manages node configuration
* Starts vSphere Pods
* Monitors vSphere Pods
NEW QUESTION # 43
Where are the virtual machine images stored that are used to deploy Tanzu Kubernetes clusters?
- A. Namespace
- B. Harbor Image Registry
- C. Content Library
- D. Supervisor Cluster
Answer: C
Explanation:
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 # 44
Which command should be used by a developer to log in to the vSphere with Tanzu Supervisor Cluster?
- A. vmwarectl vsphere login --server-<KUBERNETES-CONTROL-PLANE-IP-ADDRESS>
--vsphere-username <VCENTER-SSO-USER> - B. vmwarectl login --server-<KUBERNETES-CONTROL-PLANE-IP-ADDRESS> --vsphere-username
<VCENTER-SSO-USER> - C. kubectl vsphere login --server=<KUBERNETES-CONTROL-PLANE-IP-ADDRESS>
--vsphere-username <vcENTER-SSO-USER> - D. kubectl login --server=<KUBERNETES-CONTROL-PLANE-lP-ADDRESS> --vsphere-username
<VCENTER-SSO-USER>
Answer: C
Explanation:
Explanation
Authenticating Using kubectl
In vSphere with Tanzu, authentication is performed using vCenter Single Sign-On. You run the command kubectl vsphere login to authenticate a user through vCenter Single Sign-On to Kubernetes clusters.
kubectl vsphere login --server <kubernetes control plane> -u <username> The --insecure-skip-tls-verify flag is required if the certificate presented by the vSphere with Tanzu control plane is not trusted by the client machine. The control plane is signed by the vCenter Server VMware CA by default. You can replace the control plane certificate with a trusted certificate if needed. Alternatively, install the vCenter Server VMware CA root certificate into your client machine to remove the need for the
--insecure-skip-tls-verify flag.
NEW QUESTION # 45
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. Connectivity between the Tanzu Kubernetes cluster and the Subscribed Content Library
- B. Whether the resources provided by the virtual machine class type should be reserved on the host
- C. The amount of CPU. memory, and storage the virtual machine should have
- D. The storage classes which need to be made available to the cluster
- E. The configuration parameters which need to be edited in the cluster
Answer: B,C
Explanation:
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 # 46
Which kubectl command should be used to change the active vSphere namespace to namespace-01?
- A. kubectl config use-context namespace-01
- B. kubectl get ns namespace-01
- C. kubectl describe ns namespace-01
- D. kubectl config change-context namespace-01
Answer: A
Explanation:
A context element in a kubeconfig file is used to group access parameters under a convenient name. Each context has three parameters: cluster, namespace, and user. By default, the kubectl command-line tool uses parameters from the current context to communicate with the cluster.
To choose the current context:
kubectl config use-context ctx001
