Explanation:
AWS Systems Manager Session Manager provides secure and auditable instance management without the need for bastion hosts or open inbound ports. It natively supports logging session activity (commands and output) to Amazon CloudWatch Logs or Amazon S3. By logging directly to CloudWatch Logs, you can easily set up metric filters and CloudWatch alarms to provide automated notifications based on session log data, making this the most operationally efficient solution.

Question 48
A company runs thousands of Amazon EC2 instances that are based on the Amazon Linux 2 Amazon Machine Image (AMI). A SysOps administrator must implement a solution to record commands and output from any user that needs an interactive session on one of the EC2 instances. The solution must log the data to a durable storage location. The solution also must provide automated notifications and alarms that are based on the log data. Which solution will meet these requirements with the MOST operational efficiency?
A
Configure command session logging on each EC2 instance. Configure the unified Amazon CloudWatch agent to send session logs to Amazon CloudWatch Logs. Set up query filters and alerts by using Amazon Athena.
B
Require all users to use a central bastion host when they need command line access to an EC2 instance. Configure the unified Amazon CloudWatch agent on the bastion host to send session logs to Amazon CloudWatch Logs. Set up a metric filter and a metric alarm for relevant security findings in CloudWatch Logs.
C
Require all users to use AWS Systems Manager Session Manager when they need command line access to an EC2 instance. Configure Session Manager to stream session logs to Amazon CloudWatch Logs. Set up a metric filter and a metric alarm for relevant security findings in CloudWatch Logs.
D
Configure command session logging on each EC2 instance. Require all users to use AWS Systems Manager Run Command documents when they need command line access to an EC2 instance. Configure the unified Amazon CloudWatch agent to send session logs to Amazon CloudWatch Logs. Set up CloudWatch alarms that are based on Amazon Athena query results.
