AWS Certified Cloud Practitioner — Question 942

A company is planning to replace its physical on-premises compute servers with AWS serverless compute services. The company wants to be able to take advantage of advanced technologies quickly after the migration.
Which pillar of the AWS Well-Architected Framework does this plan represent?

Answer options

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

Correct answer: B

Explanation

The Performance efficiency pillar focuses on using computing resources efficiently and maintaining that efficiency as demand changes and technologies evolve, which includes democratizing advanced technologies by moving to managed or serverless services. Other pillars like Security, Operational excellence, and Reliability focus on protection, operational processes, and system recovery rather than resource optimization and rapid technology adoption.
