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 State Manager
AWS Systems Manager State Manager is correct because it allows you to define and enforce a configuration policy for EC2 instances, including SAP kernel parameters. Option A (EC2 User Data) runs only once at launch and cannot enforce ongoing changes. Option B (AWS OpsWorks) is a configuration management service but is not the best fit for this specific task. Option C (AWS CloudFormation) is designed for infrastructure provisioning, not for in-guest OS configuration.
