A team evaluates performance, cost, and environmental impact separately for the same architecture.
Identify the accurate pillar description.
Which statement is accurate?
Performance Efficiency, Cost Optimization, and Sustainability use different evaluation axes even when they influence one another.
Detailed explanation
Performance Efficiency addresses choosing and using resources efficiently as requirements and technology change.
Performance Efficiency addresses choosing and using resources efficiently as requirements and technology change.
Security protects data, systems, and assets; minimizing cost is a Cost Optimization concern.

Sustainability concerns energy, resource use, and environmental impact.
Sustainability concerns energy, resource use, and environmental impact.
Cost Optimization concerns business value and spending, not physical access control.

Foundation review
Different evaluation axes
Security, Reliability, Performance Efficiency, Cost Optimization, Operational Excellence, and Sustainability address different primary questions, even when one change affects several pillars.
Use the requirement
Map the stated outcome—protection, recovery, efficient resources, lower spending, effective operations, or lower environmental impact—to the corresponding pillar.
