kubectl top node shows 30% CPU used, while kubectl describe node reports 90% of CPU requested. Which statement reconciles the two?

  1. One of the two figures must be stale
  2. describe includes limits while top includes only requests
  3. top excludes system daemons from its total
  4. top measures actual use while describe sums what was reserved
Show the answer

Answer: D. top measures actual use while describe sums what was reserved

kubectl top reports consumption from the Metrics API; kubectl describe node adds up the requests the scheduler has committed. Workloads that over-request produce exactly this gap.
