CompTIA ITF+ FC0-U61 Practice Question

An uninterruptible power supply (UPS) is designed to provide emergency power when the input power source fails. A UPS can keep a server running during short-term power outages and provides enough time to properly shut down the server to prevent data loss or hardware damage if the power outage is prolonged. Surge protectors do not provide power when it's out; they only protect devices from power surges. Wi-Fi extenders, cloud storage, and cooling systems do not maintain the server's availability during power outages.
