AWS Certified Cloud Practitioner — Question 658

Which design principles should a company apply to AWS Cloud workloads to maximize sustainability and minimize environmental impact? (Choose two.)

Answer options

• A. Maximize utilization of Amazon EC2 instances.
• B. Minimize utilization of Amazon EC2 instances.
• C. Minimize usage of managed services.
• D. Force frequent application reinstallations by users.
• E. Reduce the need for users to reinstall applications.

Correct answer: A, E

Explanation

Maximizing the utilization of Amazon EC2 instances ensures that compute resources run efficiently and do not sit idle, directly reducing energy waste. Additionally, reducing how often users must reinstall applications minimizes the network bandwidth, data transfer, and energy consumed by end-user devices. Utilizing managed services actually improves sustainability by allowing AWS to optimize resource sharing and efficiency at scale, making C incorrect.
