AWS Certified Cloud Practitioner — Question 365

A company needs an AWS design solution for a distributed system. The system's components need to be set up so that one system component cannot negatively impact another component.

Which AWS architectural best practice will meet this requirement?

Answer options

• A. Use request throttling
• B. Use a stateful service
• C. Implement automatic data backups
• D. Implement loose coupling

Correct answer: D

Explanation

Loose coupling isolates components in a distributed system, ensuring that a failure or change in one component does not break or degrade the performance of others. Request throttling helps manage traffic but does not decouple components, while stateful services and backups do not address component dependency isolation.
