AWS Certified Solutions Architect – Professional — Question 166

You have setup an Auto Scaling group. The cool down period for the Auto Scaling group is 7 minutes. The first scaling activity request for the Auto Scaling group is to launch two instances. It receives the activity question at time "t", and the first instance is launched at t+3 minutes, while the second instance is launched at t
+4 minutes.
How many minutes after time "t" will Auto Scaling accept another scaling activity request?

Answer options

Correct answer: A

Explanation

The cool down period of 7 minutes starts after the first instance is launched at t+3 minutes. Therefore, Auto Scaling will accept another request 7 minutes after t+3, which is at t+10 minutes. Since the request was received at time 't', this results in 11 minutes after time 't' for the next scaling activity to be accepted. The other options do not account for the correct timing of the cool down period.
