Correct Answer: BTo deploy AWS Lambda functions and the dependent infrastructure with minimum coding effort and reliable operations, using the AWS Serverless Application Model (AWS SAM) is the most suitable approach. AWS SAM is specifically designed for building serverless applications and allows developers to define the application and its infrastructure as code. It provides built-in best practices for serverless applications and integrates seamlessly with continuous integration and continuous delivery (CI/CD) pipelines. The SAM CLI simplifies the deployment process, reducing the operational overhead and ensuring reliable and repeatable deployments. Therefore, using AWS SAM with a CI/CD pipeline aligns best with the requirements of minimizing coding effort and ensuring reliability.
