Which term refers to a power solution that uses batteries to provide uninterrupted power and allows time for safe shutdown?

• A. uninterruptible power supply (UPS)
• B. backup power generator
• C. PDU
• D. geographic dispersion

Answer: (A)

The concept here is battery-backed power that keeps equipment running without any gap when the main power fails, buying time for a safe shutdown. A UPS stores energy in batteries and delivers immediate, clean power the instant it detects a loss of utility power. This guarantees continuity for connected systems long enough to shut down gracefully or switch to another power source, protecting against data loss and equipment damage from sudden outages. A backup power generator, by contrast, typically requires time to start and may not prevent an initial power interruption, plus it relies on fuel and maintenance. A PDU is mainly about distributing power to devices and does not provide energy storage or automatic outage protection. Geographic dispersion relates to spreading resources across locations for resilience, not to battery-backed power. So the best answer is the uninterruptible power supply.
