What distinguishes a soft eviction threshold from a hard one?

  1. A soft threshold applies only to BestEffort Pods
  2. A soft threshold must be paired with a grace period, while a hard one acts at once
  3. A soft threshold is expressed as a percentage and a hard one as an absolute amount
  4. A soft threshold triggers a node condition but never an eviction
Show the answer

Answer: B. A soft threshold must be paired with a grace period, while a hard one acts at once

Soft thresholds are configured alongside eviction grace periods so a transient spike does not evict anything; a hard threshold takes effect as soon as it is crossed.
