2V0-71.23 Exam Dumps : VMware Tanzu for Kubernetes Operations Professional

A tool that can be used to backup and restore workloads on clusters provisioned by the VMware Tanzu Kubernetes Grid Service is the Velero Plugin for VMware vSphere. The Velero Plugin for VMware vSphere is an extension of Velero, an open source tool that performs backup and restore of Kubernetes resources and persistent volumes5. The plugin leverages the snapshot capabilities of vSphere to create backups of Kubernetes workloads running on vSphere-managed infrastructure, such as VMware Cloud on AWS or VMware Cloud on Dell EMC5. The plugin also supports restoring backups to the same or different clusters, as well as migrating workloads across clusters5.

To create a vSphere Namespace, the correct steps are to use the vSphere web client, select Workload Management, select Namespaces tab, and click Create Namespace. A vSphere Namespace is a logical grouping of Kubernetes resources that can be used to isolate and manage workloads on a Supervisor Cluster1. To create a vSphere Namespace, a user needs to have the vSphere Client and the required privileges to access the Workload Management menu and the Namespaces tab2. From there, the user can select the Supervisor Cluster where to place the namespace, enter a name for the namespace, configure the network settings, set the resource limits, assign permissions, and enable services for the namespace2.

A VM class in VMware vSphere with Tanzu specifies the CPU, memory, and resource reservations for a VM10. vSphere with Tanzu offers several preconfigured VM classes which you can use as is, edit, or delete. You can also create custom VM classes in your vCenter Server instance and it will be available to all Supervisor Clusters and the namespaces created in these clusters11.

When you create or edit a VM class, you can configure the following attributes:

• Name: A unique DNS compliant name that identifies the VM class.
• vCPU Count: The number of virtual CPUs (vCPUs) for a VM. This is a VM hardware configuration.
• CPU Resource Reservation: The guaranteed minimum CPU resource allocation for a VM. This value is expressed in percentage (%).
• Memory: The memory configured for a VM in MB, GB, or TB. This is a VM hardware configuration.
• Memory Resource Reservation: The guaranteed minimum memory resource allocation for a VM. This value is expressed in percentage (%).
• Storage: The storage configured for a VM in MB, GB, or TB. This is a VM hardware configuration.

The other options are incorrect because:

• Network is not an attribute that can be configured in a VM class. Network configuration is done at the namespace level by using network policies12.
• Operating system is not an attribute that can be configured in a VM class. Operating system configuration is done at the image level by using content libraries.
• PCI devices are not an attribute that can be configured in a VM class. PCI devices are not supported by vSphere with Tanzu.
