2V0-71.23 Question 203
Select 3A business is using Tanzu Kubernetes Grid (TKG) to run multiple Kubernetes clusters across their environments. The operations team needs to ensure consistent lifecycle management of these clusters, including creation, patching, upgrades, and deletion. Which of the following tools and methods are key components for managing the lifecycle of clusters in TKG?
- A
Cluster API (CAPI)
- B
Tanzu Mission Control (TMC)
- C
kubectl apply with raw YAML files
- D
Tanzu CLI
- E
vSphere HA (High Availability)
Show answer and explanation
Correct answers: A, B, D
Explanation
Cluster lifecycle management in Tanzu Kubernetes Grid relies on tools like Cluster API (CAPI) for declarative management, Tanzu Mission Control (TMC) for governance and centralized lifecycle operations, and the Tanzu CLI for direct cluster management tasks. These tools work together to ensure seamless and consistent cluster operations, making them essential for managing TKG clusters. However, tools like raw 'kubectl apply' and vSphere HA are not designed to handle the cluster lifecycle management required in this context.
- A. Correct.
Cluster API (CAPI) is a core component of Tanzu Kubernetes Grid and is responsible for cluster lifecycle management, such as creating, updating, and deleting clusters using declarative APIs.
- B. Correct.
Tanzu Mission Control (TMC) is a centralized management platform that provides governance, inspection, and lifecycle management for Kubernetes clusters, including those created with TKG.
- C. Incorrect.
While 'kubectl apply' can be used to manage Kubernetes resources, it does not provide a structured or automated way to handle the full lifecycle of TKG clusters.
- D. Correct.
The Tanzu CLI is a primary tool for managing TKG clusters. It allows administrators to create, upgrade, scale, and delete clusters easily.
- E. Incorrect.
vSphere HA (High Availability) is related to virtual machine availability and disaster recovery. It does not handle Kubernetes cluster lifecycle management in TKG.
