Exam AWS Certified Solutions Architect - Professional topic 1 question 797 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional
Question #: 797
Topic #: 1
[All AWS Certified Solutions Architect - Professional Questions]

A company runs applications on Amazon EC2 instances. The company plans to begin using an Auto Scaling group for the instances. As part of this transition, a solutions architect must ensure that Amazon CloudWatch Logs automatically collects logs from all new instances. The new Auto Scaling group will use a launch template that includes the Amazon Linux 2 AMI and no key pair.
Which solution meets these requirements?

  • A. Create an Amazon CloudWatch agent configuration for the workload. Store the CloudWatch agent configuration in an Amazon S3 bucket. Write an EC2 user data script to fetch the configuration file from Amazon S3. Configure the CloudWatch agent on the instance during initial boot.
  • B. Create an Amazon CloudWatch agent configuration for the workload in AWS Systems Manager Parameter Store. Create a Systems Manager document that installs and configures the CloudWatch agent by using the configuration. Create an Amazon EventBridge (Amazon CloudWatch Events) rule on the default event bus with a Systems Manager Run Command target that runs the document whenever an instance enters the running state.
  • C. Create an Amazon CloudWatch agent configuration for the workload. Create an AWS Lambda function to install and configure the CloudWatch agent by using AWS Systems Manager Session Manager. Include the agent configuration inside the Lambda package. Create an AWS Config custom rule to identify changes to the EC2 instances and invoke Lambda function.
  • D. Create an Amazon CloudWatch agent configuration for the workload. Save the CloudWatch agent configuration as part of an AWS Lambda deployment package. Use AWS CloudTrail to capture EC2 tagging events and initiate agent installation. Use AWS CodeBuild to configure the CloudWatch agent on the instances that run the workload.

Selected Answer: B
A and B will work however in A there is no CW agent installation (its not installed by default) just configuration. B is complete and can be managed correctly: https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/install-CloudWatch-Agent-on-EC2-Instance-fleet.html https://wellarchitectedlabs.com/security/200_labs/200_remote_configuration_installation_and_viewing_cloudwatch_logs/
