Which cloud capability enables automatic scaling of resources to meet demand without manual intervention?

• A. On-demand self-service
• B. Measured service
• C. Rapid elasticity
• D. Resource pooling

Answer: (C)

Automatic scaling of resources to meet demand without manual intervention is rapid elasticity. This capability lets the cloud automatically provision and release compute, storage, and other resources in response to workload changes, so apps stay responsive as traffic rises or falls, all without human action. It’s the feature that directly enables dynamic scaling in real time. On-demand self-service describes users provisioning resources themselves when needed, but it doesn’t by itself imply automatic scaling. Measured service is about monitoring usage and billing, not scaling behavior. Resource pooling refers to the provider’s shared infrastructure serving many tenants, not the automatic scaling of resources in response to load.
