Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Systems Manager Patch Manager
AWS Systems Manager Patch Manager is the best choice because it automates the patching of OS-level updates. Combined with Auto Scaling groups, you can perform rolling updates to avoid downtime. AWS Config (option A) is used for compliance and configuration auditing, not patching. AWS CloudFormation (option C) is an infrastructure-as-code service, not a patching solution. AWS OpsWorks (option D) supports Chef and Puppet automation but is less integrated and not the primary service for OS patching.
