Topic 1 Question 130
A company runs a web application on three Amazon EC2 instances behind an Application Load Balancer (ALB). The company notices that random periods of increased traffic cause a degradation in the application’s performance. A SysOps administrator must scale the application to meet the increased traffic.
Which solution meets these requirements?
Create an Amazon CloudWatch alarm to monitor application latency and increase the size of each EC2 instance if the desired threshold is reached.
Create an Amazon EventBridge (Amazon CloudWatch Events) rule to monitor application latency and add an EC2 instance to the ALB if the desired threshold is reached.
Deploy the application to an Auto Scaling group of EC2 instances with a target tracking scaling policy. Attach the ALB to the Auto Scaling group.
Deploy the application to an Auto Scaling group of EC2 instances with a scheduled scaling policy. Attach the ALB to the Auto Scaling group.

It's says random periods so schedule it's not an option
👍 3marcelodba2022/11/27 It would be very useful to have downvote option as well.

target tracking scaling policy is perfect for RANDOM periods of increased traffic. For those who choose D, D is NOT an option here what are you ? Wizard with crystal ball to know when traffic will increase ?
