Why each option
An Uninterruptible Power Supply (UPS) provides temporary power to a server during a blackout, allowing for graceful shutdown or continued operation for a limited time.
An Uninterruptible Power Supply (UPS) contains a battery that supplies power to connected equipment, such as a server, immediately when the main power source fails (a blackout), preventing unexpected shutdowns and potential data corruption.
A dedicated surge protector guards against voltage spikes but does not store or provide power during a blackout.
A Power Supply Unit (PSU) converts AC power to DC power for internal components and does not store energy to protect against power outages.
A redundant power supply provides a backup power path within the server if one PSU fails, but it does not protect against a complete loss of external power (blackout).
A hot-swappable power supply allows for replacement without powering down the server but does not provide power during a blackout.
A line conditioner regulates voltage fluctuations and filters noise, but it does not supply power during a blackout.
