2V0-71.23 Question 139
Select 2You are tasked with deploying a workload cluster in a VMware Tanzu Kubernetes Grid (TKG) environment. During the deployment process, you need to ensure that the workload cluster is configured to handle high availability by deploying at least three control plane nodes and uses a specific machine type for its worker nodes. Which steps should you take to successfully deploy this workload cluster?
- A
Specify the number of control plane nodes in the cluster configuration file as 3 or higher.
- B
Use the
tanzu cluster createcommand and pass the--enable-high-availabilityflag. - C
Define the machine type for worker nodes in the cluster configuration file under the
workernode pool specification. - D
Manually scale the cluster after deployment to add more control plane nodes.
- E
Ensure that a separate namespace is created in the management cluster for the workload cluster.
Show answer and explanation
Correct answers: A, C
Explanation
To deploy a workload cluster with high availability in VMware Tanzu Kubernetes Grid, you must configure the cluster appropriately in the cluster configuration file. This includes specifying at least three control plane nodes and defining the worker node machine type. These settings ensure that the workload cluster is resilient and properly resourced during deployment. Additional steps, such as namespace creation or manual scaling, are not required for high availability in this context.
- A. Correct.
Specifying the number of control plane nodes in the cluster configuration file as 3 or higher ensures high availability during deployment. This is a required step for configuring high availability in Tanzu Kubernetes Grid workload clusters.
- B. Incorrect.
The
--enable-high-availabilityflag does not exist in thetanzu cluster createcommand. High availability is configured through the cluster configuration file, not via command-line flags. - C. Correct.
Defining the machine type for worker nodes in the cluster configuration file is necessary to specify the desired resource allocation for the worker nodes. This ensures the cluster meets workload requirements.
- D. Incorrect.
Manually scaling the cluster after deployment is not the recommended approach for configuring high availability. You should configure the desired number of control plane nodes during the initial deployment.
- E. Incorrect.
While namespaces can help organize resources, creating a separate namespace for a workload cluster is not a requirement for deploying a workload cluster with high availability.
