Question 5

A company deploys its corporate infrastructure on AWS across multiple AWS Regions and Availability Zones. The infrastructure is deployed on Amazon EC2 instances and connects with AWS IoT Greengrass devices. The company deploys additional resources on on-premises servers that are located in the corporate headquarters.

The company wants to reduce the overhead involved in maintaining and updating its resources. The company’s DevOps team plans to use AWS Systems Manager to implement automated management and application of patches. The DevOps team confirms that Systems Manager is available in the Regions that the resources are deployed in. Systems Manager also is available in a Region near the corporate headquarters.

Which combination of steps must the DevOps team take to implement automated patch and configuration management across the company’s EC2 instances, IoT devices, and on-premises infrastructure? (Choose three.)

A : ply tags to all the EC2 instances, AWS IoT Greengrass devices, and on-premises servers. Use Systems Manager Session Manager to push patches to all the tagged devices.

B : Systems Manager Run Command to schedule patching for the EC2 instances, AWS IoT Greengrass devices, and on-premises servers.

C : Systems Manager Patch Manager to schedule patching for the EC2 instances, AWS IoT Greengrass devices, and on-premises servers as a Systems Manager maintenance window task.

D : nfigure Amazon EventBridge to monitor Systems Manager Patch Manager for updates to patch baselines. Associate Systems Manager Run Command with the event to initiate a patch action for all EC2 instances, AWS IoT Greengrass devices, and on-premises servers.

E : eate an IAM instance profile for Systems Manager. Attach the instance profile to all the EC2 instances in the AWS account. For the AWS IoT Greengrass devices and on-premises servers, create an IAM service role for Systems Manager.

F : nerate a managed-instance activation. Use the Activation Code and Activation ID to install Systems Manager Agent (SSM Agent) on each server in the on-premises environment. Update the AWS IoT Greengrass IAM token exchange role. Use the role to deploy SSM Agent on all the IoT devices.
