Explanation:
When multiple scaling policies are triggered simultaneously in an Amazon EC2 Auto Scaling group, the service prioritizes the policy that provides the largest capacity change. In this scenario, adding 10 instances provides more capacity than adding 5 instances, so Amazon EC2 Auto Scaling will execute the policy that adds 10 instances to ensure the application remains responsive under load.
