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 Lambda
AWS CloudFormation supports custom resources, which can invoke AWS Lambda functions to run custom scripts during stack creation, making it suitable for configuring SAP applications. Option A is wrong because AWS Systems Manager Run Command is not directly integrated into CloudFormation as a custom resource; it can be invoked via Lambda or other means but not natively. Option B is wrong because AWS CodeDeploy is used for code deployments to existing instances, not for initial configuration during CloudFormation stack creation. Option D is wrong because AWS OpsWorks is a configuration management service using Chef/Puppet, not directly integrated with CloudFormation for running custom scripts.
