Question

A company uses AWS Systems Manager to manage a fleet of Amazon Linux EC2 instances that have SSM Agent installed. All EC2 instances are configured to use Instance Metadata Service Version 2 (IMDSv2) and are running in the same AWS account and AWS Region. Company policy requires developers to use only Amazon Linux. The company wants to ensure that all new EC2 instances are automatically managed by Systems Manager after creation. Which solution will meet these requirements with the MOST operational efficiency?

Accepted Answer

Correct answer: A. The correct answer is A. Option A: Create an IAM role that has a trust policy that allows Systems Manager to assume the role. Attach the AmazonSSMManagedEC2InstanceDefaultPolicy policy to the role. Configure the default-ec2-instance-management-role SSM... Amazon EC2 provides resizable virtual servers when you need full control of the operating system. An IAM role grants temporary, least-privilege permissions to AWS resources without long-term credentials. AWS IAM controls authenticated and authorized access to AWS resources with fine-grained policies.
