VMware Carbon Black Cloud Enterprise EDR (2020) — Question 86

An administrator is tasked with horizontally scaling an existing Tanzu Kubernetes cluster from 6 to 4 nodes.

Which action does the administrator need to complete to ensure the cluster scales successfully when updating the YAML definition?

Answer options

• A. Decrease the number of control plane nodes to 4.
• B. Decrease the number of worker nodes to 4.
• C. Update the Virtual Machine Class Type.
• D. Update the Kubernetes version to the latest supported version.

Correct answer: B

Explanation

The correct answer is B because decreasing the number of worker nodes directly impacts the scaling of the cluster. Options A, C, and D do not address the requirement to scale the cluster down to 4 nodes and may even introduce additional complications or be unnecessary for the task at hand.
