A developer creates a test environment and deletes it after testing. Which cloud benefit does this best demonstrate?

The consumption-based model, also known as pay-as-you-go, directly reflects the scenario where resources are provisioned and deprovisioned as needed, and you only pay for what you use. Creating a test environment and then deleting it means the developer pays only for the time the environment existed, aligning perfectly with this model. Elasticity refers to the ability to scale resources up or down automatically to meet demand, which is a related but distinct concept. Disaster recovery involves strategies to restore operations after a failure, and geo-redundancy is a specific disaster recovery strategy involving data replication across geographical locations. These do not directly describe the cost-saving benefit of paying only for active usage.
