The technology term for the efficiency with which a system can accommodate workload growth while preserving performance and availability.

• A. Performance
• B. Usability
• C. Scalability (KPI)
• D. Recoverability

Answer: (C)

Scalability is about how well a system can handle a growing workload while keeping performance and availability intact. It means the system can expand resources or adjust capacity to meet higher demand without letting response times spike or uptime drop. That’s why the term Scalability (KPI) fits best here—the KPI framing highlights measuring how well the system grows with load, using metrics like throughput, latency, and availability as demand increases. If you describe performance alone, you’re focusing on speed under current conditions rather than growth. Usability is about how easy the system is to use, and recoverability deals with restoring operations after a disruption, not with handling increasing workloads.
