2V0-71.23 Question 137
Select 3You are tasked with deploying a workload cluster using VMware Tanzu Kubernetes Grid (TKG) on an existing vSphere infrastructure. During the deployment, you need to ensure that the cluster meets the following requirements:
- The cluster must use a specific Kubernetes version.
- The cluster must be configured to allow high availability.
- The cluster must have three control plane nodes.
Which steps should you take to successfully deploy the workload cluster?
- A
Specify the desired Kubernetes version in the cluster configuration YAML file.
- B
Set the controlPlane.replicas field to 3 in the cluster configuration YAML file.
- C
Enable the 'AllowSingleNodeControlPlane' parameter in the cluster configuration YAML file.
- D
Use the Tanzu CLI to create the workload cluster with the customized configuration file.
- E
Manually configure the vSphere environment to ensure high availability after deploying the cluster.
Show answer and explanation
Correct answers: A, B, D
Explanation
To deploy a workload cluster with specific requirements such as a specific Kubernetes version and high availability, you must modify the cluster configuration YAML file. This includes specifying the desired Kubernetes version and setting the controlPlane.replicas field for the required number of control plane nodes. The Tanzu CLI is then used to apply the configuration and create the workload cluster. High availability is handled during deployment and does not require manual configuration post-deployment.
- A. Correct.
Correct: Specifying the desired Kubernetes version in the cluster configuration YAML file ensures the workload cluster is deployed with the required version.
- B. Correct.
Correct: Setting the controlPlane.replicas field to 3 in the configuration YAML file ensures that the workload cluster has three control plane nodes for high availability.
- C. Incorrect.
Incorrect: Enabling 'AllowSingleNodeControlPlane' is used to deploy clusters with only one control plane node, which does not meet the high availability requirement.
- D. Correct.
Correct: Using the Tanzu CLI with the customized configuration file is the proper way to deploy the workload cluster with your specified settings.
- E. Incorrect.
Incorrect: High availability is configured during cluster deployment using the Tanzu Kubernetes Grid configuration file, not manually after deployment.
