Public-health expects a known parade-day surge at 09:00 and asks whether only waiting for HPA is always enough. Which statement is accurate?
Select an answer to reveal the explanation.
Short Explanation
HPA is reactive—it notices the crowd when the sensors climb. For a parade you already know about, you may still open extra gates early with a proactive scale, then let HPA help with surprises.
Full Explanation
HorizontalPodAutoscaler adjusts replicas based on observed metrics, so it responds after load appears (subject to sync and stabilization). For known events, administrators may still raise replicas proactively. HPA does not magically scale hours early without signal, nor does its mere presence ban all capacity planning.
