Selected Answer: C

Dynamic Scaling – This is yet another type of Auto Scaling in which the number of EC2 instances is changed automatically depending on the signals received. Dynamic Scaling is a good choice when there is a high volume of unpredictable traffic. https://www.developer.com/web-services/aws-auto-scaling-types-best-practices/#:~:text=Dynamic%20Scaling%20%E2%80%93%20This%20is%20yet,high%20volume%20of%20unpredictable%20traffic.
