A https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/al2-live-patching.html Amazon Linux 2 kernel live patches are made available as signed RPM packages in the existing Amazon Linux 2 repositories. The patches can be installed on individual instances using existing yum workflows, or they can be installed on a group of managed instances using AWS Systems Manager.

Correct Answer: A "Patch Manager, a capability of AWS Systems Manager, automates the process of patching managed instances with both security related and other types of updates. You can use Patch Manager to apply patches for both operating systems and applications. (On Windows Server, application support is limited to updates for applications released by Microsoft.) You can use Patch Manager to install Service Packs on Windows instances and perform minor version upgrades on Linux instances. You can patch fleets of Amazon Elastic Compute Cloud (Amazon EC2) instances or your on-premises servers and virtual machines (VMs) by operating system type." https://docs.aws.amazon.com/systems-manager/latest/userguide/systems-manager-patch.html

you can use the user data only when you create the instance, so you cannot update the instance with it .
