The Kubernetes RBAC API declares four kinds of Kubernetes object: Role, ClusterRole, RoleBinding and ClusterRoleBinding. These objects are used to define permissions and assign them to users or groups within a cluster. A Role or ClusterRole contains rulesthat represent a set of permissions on resources or non-resource endpoints. A RoleBinding or ClusterRoleBinding grants the permissions defined in a Role or ClusterRole to a set of subjects (users, groups, or service accounts). A RoleBinding applies only within a specific namespace, while a ClusterRoleBinding applies cluster-wide.

The other options are incorrect because:

• CloudPolicyObject is not a valid Kubernetes object type. It might be confused with NetworkPolicy, which is an object type that defines how pods are allowed to communicate with each other and other network endpoints.
• Container type and Container object are not valid Kubernetes object types. They might be confused with Pod, which is an object type that represents a group of one or more containers running on a node.
• ClusterObject and ClusterNode are not valid Kubernetes object types. They might be confused with Cluster and Node, which are concepts that describe the logical and physical components of a Kubernetes cluster.

The command that can be used to upgrade a VMware Tanzu Kubernetes Cluster that is managed by VMware Tanzu Mission Control is tmc cluster upgrade [version] . This command allows you to upgrade a managed cluster to a newer version of Kubernetes that is supported by Tanzu Mission Control5. The version flag is optional and specifies the target version of Kubernetes. If not specified, the command upgrades the cluster to the latest available version5. The clustername argument is required and specifies the name of the cluster to upgrade5.

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.
