  • Topic 1 Question 846

    A company’s application is running on Amazon EC2 instances within an Auto Scaling group behind an Elastic Load Balancing (ELB) load balancer. Based on the application's history, the company anticipates a spike in traffic during a holiday each year. A solutions architect must design a strategy to ensure that the Auto Scaling group proactively increases capacity to minimize any performance impact on application users.

    Which solution will meet these requirements?

    • Create an Amazon CloudWatch alarm to scale up the EC2 instances when CPU utilization exceeds 90%.

    • Create a recurring scheduled action to scale up the Auto Scaling group before the expected period of peak demand.

    • Increase the minimum and maximum number of EC2 instances in the Auto Scaling group during the peak demand period.

    • Configure an Amazon Simple Notification Service (Amazon SNS) notification to send alerts when there are autoscaling:EC2_INSTANCE_LAUNCH events.
