AWS Certified Cloud Practitioner (CLF-C02) — Question 56

A company is running a monolithic on-premises application that does not scale and is difficult to maintain. The company has a plan to migrate the application to AWS and divide the application into microservices.
Which best practice of the AWS Well-Architected Framework is the company following with this plan?

Answer options

• A. Integrate functional testing as part of AWS deployment.
• B. Use automation to deploy changes.
• C. Deploy the application to multiple locations.
• D. Implement loosely coupled dependencies.

Correct answer: D

Explanation

The correct answer is D, as implementing loosely coupled dependencies is a fundamental principle of microservices architecture. This approach allows services to be developed, deployed, and scaled independently, enhancing maintainability. The other options focus on deployment practices rather than the architectural strategy that the company is adopting.
