Question

Options

• AThe ability to support development and run workloads effectively
• BThe ability of a Workload to function correctly and consistently in all expected
• CThe ability to use cloud resources efficiently for meeting system requirements, and maintaining

• A

• B
  3% (2)
• C
  2% (1)
• D
  90% (57)

Explanation

Option D correctly defines the Security pillar of the AWS Well-Architected Framework's Five Pillars, which focuses on architecting every workload to prevent, detect, and respond to security threats - protecting data, systems, and assets through proper identity management, detection controls, and incident response.

Option A describes Operational Excellence, which is about running and monitoring workloads to deliver business value and continually improve processes. Option B describes Reliability, which covers a workload's ability to perform its intended function correctly and recover from failures. Option C describes Performance Efficiency (or partially Cost Optimization), which is about using computing resources efficiently to meet requirements and sustain that efficiency as demand changes.

Memory tip: Think of the Five Pillars as CROPS - Cost Optimization, Reliability, Operational Excellence, Performance Efficiency, Security. Security is the only pillar explicitly concerned with preventing harm at the architectural level, so any answer mentioning "protect," "prevent," or "defend" points to the Security pillar.
