Practice question 72 of 440 · hard

An eight-core system averages modest CPU usage, but one core remains near saturation during failures. What does this show?

Choose the single best answer.

  1. A.Aggregate CPU averages can hide a bottleneck on one core
  2. B.Low average CPU excludes any processing bottleneck
  3. C.Memory conserve mode is definitely active
  4. D.Every session is guaranteed to be hardware-offloaded
Show the answer and explanation

✓ Correct answer

  • Aggregate CPU averages can hide a bottleneck on one core

Per-core saturation can coexist with a lower aggregate average. It does not prove conserve mode or universal acceleration, and low average CPU alone cannot exclude a bottleneck.
