2V0-71.23 Question 143
Select 3You are tasked with attaching an existing Kubernetes cluster to VMware Tanzu Mission Control (TMC) for centralized management and observability. The cluster runs on a public cloud provider and was not created using TMC. During the attachment process, what steps must you perform to successfully attach the cluster?
- A
Download the TMC agent YAML file and apply it to the Kubernetes cluster using kubectl.
- B
Ensure the Kubernetes cluster has connectivity to the TMC endpoint.
- C
Install the Tanzu CLI on the control plane nodes of the Kubernetes cluster.
- D
Generate an authentication token in TMC for the cluster attachment process.
- E
Label all Kubernetes nodes with the 'attached-by-tmc' label to indicate the cluster is managed by TMC.
Show answer and explanation
Correct answers: A, B, D
Explanation
To attach an existing Kubernetes cluster to VMware Tanzu Mission Control, the process involves downloading and applying the TMC agent YAML file to the cluster, ensuring network connectivity to TMC endpoints, and generating an authentication token for secure attachment. These steps enable the TMC agent to be installed and configured, allowing TMC to manage the cluster. Additional steps, such as installing the Tanzu CLI or labeling nodes, are not part of the standard attachment workflow.
- A. Correct.
Correct: The TMC agent YAML file is required to establish communication between the Kubernetes cluster and TMC. Applying the YAML file installs the agent components needed for the attachment.
- B. Correct.
Correct: The Kubernetes cluster must have network connectivity to TMC endpoints to facilitate communication and management.
- C. Incorrect.
Incorrect: Installing the Tanzu CLI on the control plane nodes is not a required step for attaching a cluster to TMC. The CLI is used for creating and managing clusters but not for attaching existing ones.
- D. Correct.
Correct: Generating an authentication token in TMC is necessary to authenticate the attachment process and establish trust between the cluster and TMC.
- E. Incorrect.
Incorrect: Labeling nodes with 'attached-by-tmc' is not a required step in the attachment process. Node labels are not used to indicate cluster attachment status.
