Topic 1 Question 221
A company uses AWS Organizations to manage its AWS accounts. The company needs a list of all its Amazon EC2 instances that have underutilized CPU or memory usage. The company also needs recommendations for how to downsize these underutilized instances.
Which solution will meet these requirements with the LEAST effort?
Install a CPU and memory monitoring tool from AWS Marketplace on all the EC2 instances. Store the findings in Amazon S3. Implement a Python script to identify underutilized instances. Reference EC2 instance pricing information for recommendations about downsizing options.
Install the Amazon CloudWatch agent on all the EC2 instances by using AWS Systems Manager. Retrieve the resource optimization recommendations from AWS Cost Explorer in the organization’s management account. Use the recommendations to downsize underutilized instances in all accounts of the organization.
Install the Amazon CloudWatch agent on all the EC2 instances by using AWS Systems Manager. Retrieve the resource optimization recommendations from AWS Cost Explorer in each account of the organization. Use the recommendations to downsize underutilized instances in all accounts of the organization.
Install the Amazon CloudWatch agent on all the EC2 instances by using AWS Systems Manager. Create an AWS Lambda function to extract CPU and memory usage from all the EC2 instances. Store the findings as files in Amazon S3. Use Amazon Athena to find underutilized instances. Reference EC2 instance pricing information for recommendations about downsizing options.

Actually, the right answer is to use Compute Optimizer, I don't understand why it was not part of the choices here https://aws.amazon.com/compute-optimizer/

B. That's why you have the management account so you don't have to go to 1000+ accounts and get metrics.

This solution leverages the capabilities of AWS CloudWatch and AWS Cost Explorer to monitor and analyze the CPU and memory usage of EC2 instances. By installing the CloudWatch agent, you can collect the necessary metrics for monitoring. AWS Cost Explorer provides resource optimization recommendations, which can be accessed from the organization's management account. These recommendations can then be used to identify underutilized instances and make informed decisions about downsizing.
This solution requires minimal effort as it utilizes existing AWS services and tools, eliminating the need for additional installations or custom scripts. It also provides a centralized approach by retrieving recommendations from the organization's management account, allowing for efficient management of all accounts within the organization.
