2V0-71.23 Question 235
Select 4An organization is deploying VMware Tanzu Kubernetes Grid (TKG) in their environment and is evaluating the Supervisor Cluster as part of their setup. Which of the following statements correctly describe the Supervisor Cluster?
- A
The Supervisor Cluster is a vSphere cluster enabled with the Workload Management feature.
- B
The Supervisor Cluster allows running Kubernetes workloads directly on ESXi hosts without requiring virtual machines.
- C
The Supervisor Cluster requires an NSX-T Data Center or vSphere Distributed Switch for network configuration.
- D
The Supervisor Cluster only supports Kubernetes versions provided by external distributions like OpenShift.
- E
The Supervisor Cluster uses a Kubernetes API to manage workloads, namespaces, and policies.
Show answer and explanation
Correct answers: A, B, C, E
Explanation
The Supervisor Cluster is the foundation of VMware Tanzu Kubernetes Grid on vSphere. It enables Kubernetes functionality by integrating Kubernetes into vSphere and leveraging ESXi hosts for running workloads natively. It requires specific network configurations, such as NSX-T or vSphere Distributed Switch, and provides a Kubernetes API for seamless management of namespaces, workloads, and policies. However, it does not rely on external Kubernetes distributions like OpenShift.
- A. Correct.
Correct: The Supervisor Cluster is essentially a vSphere cluster that has been enabled with Workload Management, allowing it to run Kubernetes workloads.
- B. Correct.
Correct: One of the unique features of the Supervisor Cluster is that it runs Kubernetes workloads directly on ESXi hosts through a technology called 'Spherelet', avoiding the need for traditional virtual machines.
- C. Correct.
Correct: The Supervisor Cluster requires either NSX-T or vSphere Distributed Switch for networking to support Kubernetes' container networking requirements.
- D. Incorrect.
Incorrect: The Supervisor Cluster uses VMware's own native Kubernetes distribution and does not rely on external distributions like OpenShift.
- E. Correct.
Correct: The Supervisor Cluster exposes a Kubernetes API that administrators and developers can use to manage Kubernetes workloads, namespaces, and policies.
