How does a target tracking scaling policy behave if the metric value is consistently below the target value?
AIt decreases capacity to try to reach the target
BIt increases capacity to try to reach the target
CIt does not change capacity
DIt disables scaling temporarily
Step-by-Step Solution
Solution:
  1. Step 1: Understand target tracking behavior

    If metric is below target, policy decreases capacity to bring metric up to target.
  2. Step 2: Confirm no disabling or ignoring

    Policy actively adjusts capacity; it does not disable scaling or ignore metric.
  3. Final Answer:

    It decreases capacity to try to reach the target -> Option A
  4. Quick Check:

    Metric below target = scale down [OK]
Quick Trick: Below target metric triggers scale down [OK]
Common Mistakes:
  • Thinking it increases capacity when metric is low
  • Assuming no action if metric is below target
