Exam AWS Certified SysOps Administrator - Associate topic 1 question 474 discussion

In the scenario described, if an Amazon EC2 Auto Scaling group has two scaling policies that both trigger at the same CPU utilization level (80% in this case), and if both policies are active, then both will be executed when the threshold is reached. This means that if one policy adds 5 instances and the other adds 10 instances when the CPU utilization hits 80%, then a total of 15 instances will be added to the Auto Scaling group if the threshold is met and sustained for the duration specified by the policy's cool-down period.In a real-world scenario, the execution of scaling policies would also be influenced by the cooldown timers set within the Auto Scaling group configuration. If the cooldown period is still in effect from a previous scaling activity, it may temporarily prevent another scaling activity from being triggered by the second policy. But assuming that both policies are able to trigger without any cooldown conflicts, the described behavior (adding a total of 15 instances) would occur.
