Which of the following promotes AWS Cloud architectural best practices for designing and operating reliable, secure, efficient, and cost-effective systems?
AWS Serverless Application Model framework
AWS Business Support
Principle of least privilege
AWS Well Architected Framework
Explanations:
AWS Serverless Application Model (SAM) is a framework for building serverless applications, not a set of best practices.
AWS Business Support provides technical support and guidance but does not specifically focus on architectural best practices.
Principle of least privilege is a security best practice, but it does not encompass the full scope of AWS architectural best practices.
AWS Well-Architected Framework provides a comprehensive set of best practices across security, reliability, efficiency, and cost optimization.
From what I’ve seen, the answer is:
