kubectl version prints a client version but no server version. What does that indicate?

  1. A version skew between client and server
  2. That the user lacks RBAC permission to read the version
  3. That the cluster is running an aggregated API server
  4. That kubectl cannot reach the cluster at all
Show the answer

Answer: D. That kubectl cannot reach the cluster at all

The server version is fetched over the connection, so its absence points at connectivity or configuration rather than at kubectl itself.
