Answer 1

Correct answer: "The ability to handle a large amount of data efficiently."

Brief explanation: database scalability means the system can grow to accommodate increasing data volume and/or user load while maintaining acceptable performance. This can be achieved by vertical scaling (bigger machines) or horizontal scaling (more servers). Adding hard drives is one way to increase capacity but is not the full definition.
