2. You have a large multi-tier architecture that serves public facing web traffic through a load balancer and is backed by a web tier that Is contained within an Amazon EC2 Auto Scaling group. During a peak in traffic, you discover that your web tier is adding new Instances disproportionately compared to the amount of Incoming traffic and the Auto Scaling policy that was set up. What should you do in order to stop the Auto Scaling group from scaling incorrectly in response to incoming traffic?

A) Using Cloud Watch and the instance Boot Time metric, increase the Pause Time and Cool Down property on I the Auto Scaling group to be over the value of the metric.
B) Using a custom Cloud Watch metric insert the elapsed time since the instance launch to the time the instance responds to an Elastic Load Balancing health check, and periodically adjust the Pause Time of the Update Policy and reduce the Scaling Adjustment property by 50%
C) Using a third-party configuration management tool and the AWS(Amazon Web Service) SDK suspend all Scheduled Actions of the Auto Scaling group until after the traffic peak and then resume all scheduled Actions.
D) Using a custom Cloud Watch metric insert the elapsed time since the instance launch to the time the instance responds to an Elastic Load Balancing health check, and periodically adjust the Pause Time and the Cool Down property on the Auto Scaling group to be over the value of the metric.
