Selected Answer: C
Free disk space is available from Linux OS directly, but you'd have to connect to each machine one by one. For Windows, or to monitor across multiple instances simultaneously (Linux and/or Windows) you need the CloudWatch Agent per this page. https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-describing-volumes.html#ebs-view-free-disk-space which states " If you need to monitor disk space usage for multiple instances, you can install and configure the CloudWatch agent on those instances using Systems Manager. For more information, see Installing the CloudWatch agent using Systems Manager."

Option A (Use built-in Amazon CloudWatch metrics, and configure CloudWatch alarms and an Amazon SNS topic for email notifications) is the correct option. Amazon CloudWatch provides built-in metrics for monitoring EBS volumes, including the volume's free space. By setting up CloudWatch alarms on the free space metric, the administrator can receive email notifications (using an Amazon SNS topic) when the free space on the EBS volume drops below a specified threshold. This proactive alerting will allow the administrator to take appropriate actions to prevent low storage space from affecting EC2 instance performan

No, this is incorrect. There are no built-in metrics for monitoring free space on EBS volumes. You need to install and configure CloudWatch agent. https://docs.aws.amazon.com/AWSEC2/latest/WindowsGuide/ebs-describing-volumes.html#ebs-view-free-disk-space

Option C (Use the Amazon CloudWatch agent to send disk space metrics, then set up CloudWatch alarms using an Amazon SNS topic) is not the most suitable option for monitoring EBS volumes on Microsoft Windows-based EC2 instances. While the CloudWatch agent can be used to collect additional custom metrics, Amazon CloudWatch already provides built-in metrics for monitoring EBS volumes' free space without the need for additional configuration on Windows EC2 instances.
