CKA study material · question 207 of 1000

An administrator sets a nodePort explicitly. Which two responsibilities does that create? Choose two.

  1. Choosing a value inside the configured NodePort range
  2. Opening the port on the API server
  3. Avoiding collisions with ports already allocated
  4. Matching the value to the Service's targetPort
Show the answer

Answer: C. Avoiding collisions with ports already allocated
A. Choosing a value inside the configured NodePort range

The control plane grants the requested port or fails, so collisions and range are the administrator's concern.

Source: Service (Kubernetes) — type: NodePort
