Answer is B - "Scheduled scaling helps you to set up your own scaling schedule according to predictable load changes. For example, let's say that every week the traffic to your web application starts to increase on Wednesday, remains high on Thursday, and starts to decrease on Friday. You can configure a schedule for Amazon EC2 Auto Scaling to increase capacity on Wednesday and decrease capacity on Friday." https://docs.aws.amazon.com/autoscaling/ec2/userguide/schedule_time.html

Selected Answer: B

I know when I want to scale up - predictable. Target tracking is only for unpredictable workloads. Lambda + EB is not the most op efficient. Cooldown does not apply here.
