Exam AWS Certified Cloud Practitioner topic 1 question 651 discussion

The AWS services that can provide information on whether the newly imported Amazon EC2 instances are the appropriate size and type are AWS Compute Optimizer and AWS Trusted Advisor. Therefore, options C and D are correct. AWS Auto Scaling is a service used to automatically scale resources to maintain application availability and performance. AWS Control Tower is a service that provides a central, automated governance for multiple accounts and resources across an organization. Amazon Forecast is a service that uses machine learning to make time-series predictions.

Option C: AWS Trusted Advisor is a service that provides real-time guidance to help optimize AWS resources and improve security and performance. It includes recommendations for cost optimization, security, fault tolerance, and performance improvement. In this case, the company can use the EC2 Instance Size Optimization recommendation to determine whether its imported EC2 instances are the appropriate size. Option D: AWS Compute Optimizer is a service that analyzes resource utilization metrics and provides recommendations for the optimal size and types of EC2 instances, as well as the best purchase option (on-demand, reserved, or spot instances) for each workload. The company can use this service to identify which EC2 instances need to be resized or replaced with a different instance type.

Definitely C & D. A is for autoscaling based on demand, not changing your instance type (size)
