AWS Certified Cloud Practitioner — Question 739

A company is launching a mobile app. The company wants customers to be able to use the app without upgrading their mobile devices.

Which pillar of the AWS Well-Architected Framework does this goal represent?

Answer options

• A. Security
• B. Reliability
• C. Cost optimization
• D. Sustainability

Correct answer: D

Explanation

Designing applications to support older user devices aligns with the Sustainability pillar because it extends the lifespan of consumer hardware and reduces electronic waste. While Security, Reliability, and Cost Optimization are critical pillars of the AWS Well-Architected Framework, they focus on data protection, system resilience, and cloud spending, respectively, rather than the environmental impact of end-user devices.
