Hi there!
In the CKAD course on Udemy from Mumshad, under the quiz section for taints and tolerations, I have a question.

The task is to remove the taint NoSchedule from the node controlplane. The controlplane node currently has 2 taints

  1. http://node-role.kubernetes.io/control-plane:NoSchedule|node-role.kubernetes.io/control-plane:NoSchedule
  2. http://node-role.kubernetes.io/master:NoSchedule|node-role.kubernetes.io/master:NoSchedule
    The question says:
    Remove the taint on controlplane, which currently has the taint effect of NoSchedule.

the hint section says:
Run the command: kubectl taint nodes controlplane <http://node-role.kubernetes.io/master:NoSchedule-|node-role.kubernetes.io/master:NoSchedule-> to untaint the node.

However, is it not the case that both taints must be removed as they both imply NoSchedule? I am guessing I am missing something and anyone who can enlighten me would be appreciated. Thanks!

I would remove both.

Sudi Krishnakumar:
Thanks @Shwetha, I did that and the answer was correct! I am guessing the quiz material needs updating
