Topic 1 Question 60
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.

AWS Auto Scaling Group provide users an automated approach to increase or decrease cloud resources (e.g., compute, memory, and network bandwidth) as needs changes. Hence, the answer is narrowed down to C or D.
The question states “during random moments of heightened traffic”. Option D is not the best choice, implementing a “scheduled scaling policy” would be hit or miss for “random moments of heightened traffic”.
The best choice is option “C” Deploy the Application to an Auto Scaling group of EC2 instances with a target tracking policy…
