Question

Quizplus · Accepted Answer

The Auto Scaling group will increase the capacity by 1 to 6 instances due to the first trigger. The cooldown period prevents any further scaling actions for 5 minutes, so the second trigger to decrease the capacity will not take effect until after the cooldown period ends. Thus, the count remains at 6 instances at the end of 4 minutes.
