Question 2

An e-commerce company is running on Oracle Cloud Infrastructure (OCI) and many compute instances remain unused for the most part of the year except during Black Friday and Christmas. You suggest they use OCI's autoscaling feature and present them a slide to showcase the features of autoscaling.
Which option is inaccurate in your presentation to the customer?
Response:

A. When an instance pool scales in, instances are terminated in this order: The number of instances is balanced across availability domains, and then balanced across fault domains. Finally, within a fault domain, the newest instance is terminated first. B. Autoscaling relies on performance metrics such as CPU utilization that are collected by the OCI Monitoring service to trigger an autoscaling event. C. Autoscaling requires an instance pool as a prerequisite so that it can automatically adjust the number of compute instances in an instance pool. D. A cooldown period between autoscaling events lets the system stabilize at the updated level.
