City hall loses utility power for two minutes, then later faces a multi-hour outage during a storm. Which power-resilience pairing correctly describes UPS and generator roles?
Select an answer to reveal the explanation.
Short Explanation
A UPS is the bridge across a short blackout—enough time for systems to ride through or hand off cleanly. Generators take the longer shifts when the storm knocks power out for hours. Backups store data; they do not keep the lights and servers running.
Full Explanation
Uninterruptible power supplies provide conditioned power and short-duration runtime that bridges brief outages and supports orderly transfer. Generators supply longer-duration facility power when utility loss extends beyond UPS capacity. Treating generators as flicker-only devices or claiming UPS alone covers multi-day outages misstates their roles. Data backups protect information but do not substitute for power continuity controls in resilience architecture.
