A DevOps team must create and destroy test environments rapidly. Which cloud concept provides that flexibility?

Agility is the correct answer because it refers to the cloud's ability to rapidly provision and deprovision resources, scale up or down as needed, and adapt quickly to changing demands. This flexibility is crucial for DevOps teams that need to create and destroy test environments frequently without significant lead time or manual effort. Resource Locks prevent accidental deletion or modification of resources, which is the opposite of rapid destruction. Capital Expenditure (CapEx) is a financial concept related to upfront investments, not operational flexibility. On-premises infrastructure typically lacks the rapid provisioning and scaling capabilities inherent in cloud environments, making it less agile for this use case.
