Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS CloudFormation
Why it's wrong here
CloudFormation is for infrastructure as code, not patching.
- ✓
AWS Systems Manager Patch Manager
Why this is correct
Patch Manager automates OS patching and integrates with maintenance windows.
- ✗
AWS Config
Why it's wrong here
AWS Config evaluates resource configurations but does not apply patches.
- ✗
Amazon Inspector
Why it's wrong here
Amazon Inspector is a vulnerability management service that scans for software vulnerabilities and unintended network exposure, but it does not apply patches—it only identifies missing patches. The scenario requires automated *patching*, not just detection. Inspector would be correct if the task were to assess which patches are missing before a separate tool like AWS Systems Manager Patch Manager applies them.
