A financial firm wants to innovate faster without waiting for new hardware. Which cloud computing feature enables this?

Agility is the correct answer because it refers to the cloud's ability to rapidly provision and deprovision resources, allowing organizations to quickly adapt to changing business needs and innovate without the delays associated with traditional hardware procurement. This directly addresses the firm's desire to innovate faster. Compliance, data residency, and disaster recovery are important cloud features, but they do not directly relate to the speed of innovation and resource provisioning. Compliance ensures adherence to regulations, data residency dictates where data is stored, and disaster recovery focuses on business continuity after an outage. While these are critical for a financial firm, they don't explain how cloud computing enables faster innovation through rapid resource scaling.
