How can a vSphere administrator replace the Supervisor Cluster API endpoint certificate?
- A . Use the certificate-manager CLI utility to replace the Supervisor Cluster API endpoint certificate.
- B . Use the vSphere Client to replace the Workload platform MTG certificate.
- C . Use the vSphere Client to replace the NSX Load Balancer certificate.
- D . Use kubectl to replace the Supervisor Cluster API endpoint certificate.
B
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.

The vSphere administrator defines and assigns VM storage policies to a namespace:
• VM storage policies are translated into Kubernetes storage classes.
• Developers can access all assigned VM storage policies in the form of storage classes.
• Developers cannot manage storage classes.
Storage class names are created in the following way:
• Spaces in VM Storage Policy names are replaced with hyphens (-).
• Special characters are replaced with a digit. A VM Storage Policy called My Gold Policy $ is called my-gold-policy-0 as a storage class.
Which statement accurately describes the upgrade of a vSphere with Tanzu Supervisor Cluster?
- A . vCenter Server performs an in-place upgrade of the Supervisor Cluster control plane VMs.
- B . vCenter Server orchestrates the rolling upgrade of Supervisory control plane VMs and upgrades the ESXi host spherelet component.
- C . An administrator manually deploys new Supervisor Cluster control plane VMs and uses vSphere Lifecycle Manager to update the ESXi host spherelet component.
- D . An administrator downloads and installs new RPMs to the Supervisor Cluster control plane VMs.
How does Kubernetes implement the vSphere storage policy in vSphere with Tanzu?
- A . Storage class
- B . Paravirtual CSl
- C . Static Persistent Volume
- D . Persistent Volume
A
Explanation:
When vSphere with Tanzu converts storage policies that you assign to namespaces into Kubernetes storage classes, it changes all upper case letters into lower case and replaces spaces with dashes (-). To avoid confusion, use lower case and no spaces in the VM storage policy names.
Storage Policy Based Management is a vCenter Server service that supports provisioning of persistent volumes and their backing virtual disks according to storage requirements described in a storage policy.
To which set of networks are the Supervisor Cluster nodes attached when deploying with an NSX-T network topology?
- A . Frontend and Workload
- B . Frontend and Management
- C . Workload and Management
- D . Management and NSX Overlay
C
Explanation:
The Network Service has been extended to support the vSphere Distributed Switch (vDS). Start by configuring the switch with appropriate portgroups. Management will carry traffic between vCenter and the Kubernetes Control Plane (Supervisor Cluster control plane). As we will see in a moment, not having the built in Load Balancing capability of NSX means you will need to deploy your own load balancer externally from the cluster. We will give you a choice of integrated load balancers. The first one we support is HAProxy.
The Management network will also carry traffic between the supervisor cluster nodes and HAProxy. The Frontend network will carry traffic to the Load Balancer virtual interfaces. It must be routable from any device that will be a client for your cluster. Developers will use this to issue kubectl commands to the Supervisor cluster or their TKG clusters. You can have one or more Workload networks.
The primary Workload network will connect the cluster interfaces of the Supervisor cluster. Namespaces can be defined with their own Workload network allowing for isolation between development teams assigned different Namespaces. The Namespace assigned Workload Networks will connect the TKG cluster nodes in that Namespace.

Which capability do persistent volumes provide to containerized applications?
- A . Automated disk archival
- B . Support for in-memory databases
- C . Support for ephemeral workloads
- D . Retention of application state and data
D
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.

Explanation:
A Supervisor Cluster namespace is a combination of resource allocations and permissions set within the Supervisor Cluster. When you create a Supervisor Namespace, you’ll assign who has access to use it, and how many of the ESXi cluster’s resources you can use (much like a resource pool).
When you enabled the Workload Management components, you created a special Kubernetes cluster called the “Supervisor Cluster”. You can continue to deploy virtual machines in this cluster, and you can also deploy kubernetes pods as a “pod vm” which is basically a container with some special wrapping so they are better isolated, like a virtual machine is.
What is the minimum number of virtual distributed portgroups that must be configured on the vSphere Distributed Switch before enabling Workload Management using the vSphere networking stack and a HAProxy load balancer?
- A . 2
- B . 1
- C . 4

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 . Whether the resources provided by the virtual machine class type should be reserved on the host
- B . The configuration parameters which need to be edited in the cluster
- C . The amount of CPU. memory, and storage the virtual machine should have
- D . Connectivity between the Tanzu Kubernetes cluster and the Subscribed Content Library
- E . The storage classes which need to be made available to the cluster
A,C
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.
