[All NCP-AIO Questions]

You are setting up a Kubernetes cluster on NVIDIA DGX systems using BCM, and you need to initialize the control-plane nodes.

What is the most important step to take before initializing these nodes?

Show Suggested Answer Hide Answer
Suggested Answer: B

Comprehensive and Detailed Explanation From Exact Extract:

Disabling swap on all control-plane nodes is a critical prerequisite before initializing Kubernetes control-plane nodes. Kubernetes requires swap to be disabled to maintain performance and stability. Failure to disable swap can cause kubeadm initialization to fail or lead to unpredictable cluster behavior.

Okay, let me think this through. Disabling swap, setting up a load balancer, making sure Docker is installed - they all seem important. I'll have to carefully consider each option to determine the single most important step.
