Which factor is least relevant to autoscaling decisions?

• A. The CPU utilization metric
• B. The request latency
• C. The number of instances currently running
• D. The color of the management console

Answer: (D)

Autoscaling decisions are driven by workload and performance signals, not appearances or UI aspects. The color of the management console has no impact on how traffic or load is interpreted, so it’s irrelevant to autoscaling. In contrast, CPU utilization is a primary signal: when processor demand climbs, adding more instances helps maintain performance. Request latency is also crucial because it reflects the user experience; if latency increases, scaling helps push responses faster. The number of instances currently running matters too, since it defines current capacity and interacts with limits and scaling steps; the autoscaler uses this to ensure it stays within configured minimum and maximum replicas and to determine how aggressively to scale.
