VMware vSphere with Tanzu Specialist Free Sample Questions

VM classes are defined at the Supervisor Cluster level but must be explicitly associated with a vSphere Namespace to be usable within it. If no VM classes are added to the namespace, the Tanzu Kubernetes Grid Service cannot find a suitable class to provision the control plane and worker nodes for a new TKC, leading to this specific error.

VM Classes define the CPU, memory, and reservation settings for virtual machines, directly corresponding to the T-shirt sizes for TKC nodes. Multiple classes must be created to offer different sizes.

After VM Classes are created at the Supervisor Cluster level, they must be assigned to the specific vSphere Namespace where developers will be deploying their TKCs. This makes the T-shirt sizes available within that namespace.

This statement is false. The Supervisor Cluster provides its own internal IPAM capabilities when configured with VDS networking, eliminating the need for an external or third-party IPAM solution for vSphere Pods.

This is the correct Kubernetes-native approach. A default-deny ingress policy establishes a zero-trust baseline. Then, specific 'allow' ingress policies are created for each service, using pod selectors to precisely define which source pods can connect to which destination pods on specific ports. The NSX Container Plugin (NCP) translates these Kubernetes objects into underlying NSX-T firewall rules automatically.

When vSphere with Tanzu is configured with VDS networking, a load balancer based on HAProxy is automatically deployed as a virtual machine. This appliance provides Layer 4 load balancing for the Supervisor Cluster's control plane and for Kubernetes services of type LoadBalancer created within the namespaces.

The kubectl vsphere login command authenticates the user against vCenter SSO and retrieves a temporary token. It then adds a new context, cluster, and user entry to the user's local kubeconfig file (typically located at ~/.kube/config), allowing subsequent kubectl commands to be authenticated against the target cluster.

The standard Kubernetes method for requesting storage is to create a PersistentVolumeClaim (PVC). In a vSphere with Tanzu environment, vSphere storage policies are automatically exposed as StorageClasses. The developer creates a PVC manifest that specifies the size requirement (50 GiB) and sets the storageClassName field to 'fast-ssd'. This tells vSphere to provision a persistent volume on a datastore that complies with the 'fast-ssd' policy.

The Spherelet is a VMware-developed equivalent of a Kubelet that is integrated directly into the ESXi hypervisor. It allows the Supervisor Cluster's Kubernetes control plane to communicate with the ESXi host, register it as a node, and manage the lifecycle of vSphere Pods directly on the hypervisor, providing a secure and performant way to run containers.

Tanzu Kubernetes Clusters are managed declaratively via a Custom Resource Definition (CRD). The supported method to trigger a rolling upgrade is to edit the cluster's manifest, change the Kubernetes version specified in the distribution.version field to a supported, available version, and then re-apply the manifest. The TKG controllers will then orchestrate a rolling update of the control plane and worker nodes.

Permissions on the vSphere Namespace (like 'Edit' or 'View') do not automatically grant access to the integrated Harbor registry. Harbor maintains its own authentication. Users must perform a separate docker login command using their vCenter SSO username and password. This authenticates their client session specifically with the registry service.
