AWS Certified Cloud Practitioner (CLF-C02) — Question 332

A company is designing its AWS workloads so that components can be updated regularly and so that changes can be made in small, reversible increments.

Which pillar of the AWS Well-Architected Framework does this design support?

Answer options

• A. Security
• B. Performance efficiency
• C. Operational excellence
• D. Reliability

Correct answer: C

Explanation

The Operational Excellence pillar focuses on running and monitoring systems to deliver business value, and continually improving supporting processes and procedures. A key design principle of this pillar is to make frequent, small, reversible changes, which allows components to be updated regularly with minimal risk. Other pillars, such as Security, Reliability, and Performance Efficiency, address different architectural concerns like protection, recovery, and resource optimization.
