CKA study material · question 45 of 1000

Two cloned virtual machines fail to join a cluster as distinct nodes. Which file would you read to confirm the cause?

  1. /etc/kubernetes/kubelet.conf
  2. /etc/machine-id
  3. /proc/sys/kernel/random/uuid
  4. /sys/class/dmi/id/product_uuid
Show the answer

Answer: D. /sys/class/dmi/id/product_uuid

The product_uuid is read from that path, and cloned virtual machines sometimes share one.

Source: Installing kubeadm (Kubernetes) — Verify the MAC address and product_uuid are unique for every node
