2V0-21.23 Question 295
Select 3You are tasked with configuring a Tanzu Kubernetes Grid (TKG) cluster on vSphere infrastructure for your organization. The requirements include setting up a cluster with highly available control plane nodes and ensuring that the cluster network supports pod-to-pod communication. Which of the following steps should you take to meet these requirements?
- A
Deploy a management cluster with at least three control plane nodes.
- B
Configure an NSX Advanced Load Balancer to handle control plane traffic.
- C
Set up an overlay network using a Container Network Interface (CNI) plugin like Calico or Antrea.
- D
Manually configure pod network routes using vSphere Standard Switches.
- E
Enable the 'High Availability' option during the workload cluster deployment wizard.
Show answer and explanation
Correct answers: B, C, E
Explanation
To configure a Tanzu Kubernetes Grid (TKG) cluster with highly available control plane nodes and support for pod-to-pod communication, you must configure an NSX Advanced Load Balancer for load balancing, enable the 'High Availability' option during workload cluster deployment, and set up a CNI plugin like Calico or Antrea for overlay networking. These steps ensure the cluster meets the requirements for high availability and network communication.
- A. Incorrect.
Deploying a management cluster with three control plane nodes is not required. The management cluster can have a single control plane node, and the workload cluster can be configured for high availability instead.
- B. Correct.
Configuring an NSX Advanced Load Balancer is necessary to handle API server requests and ensure load balancing for highly available control plane nodes.
- C. Correct.
Using a Container Network Interface (CNI) plugin like Calico or Antrea is mandatory to provide overlay networking, enabling pod-to-pod communication across nodes.
- D. Incorrect.
Manually configuring pod network routes using vSphere Standard Switches is not a standard or recommended approach. This is handled by the CNI plugin in Tanzu Kubernetes Grid.
- E. Correct.
Enabling the 'High Availability' option during workload cluster deployment ensures that the control plane nodes are configured for high availability, meeting the requirement for redundancy.
