Selected Answer: C
Installing the CloudWatch agent on the EC2 instances is the recommended approach for monitoring custom metrics like memory usage. The CloudWatch agent allows you to collect both standard and custom metrics from the EC2 instances and send them to CloudWatch at regular intervals. This provides a flexible and scalable solution for monitoring various metrics, including memory utilization, across a large EC2 fleet.

Answer is C . The CloudWatch monitoring scripts are deprecated. We provide information about the monitoring scripts for customers who have not yet migrated from the deprecated monitoring scripts to the CloudWatch agent. We recommend that you use the CloudWatch agent to collect metrics and logs. https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/monitoring-scripts-intro.html

It should be C. The CloudWatch monitoring scripts are already deprecated. https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/mon-scripts.html
