To preserve data integrity during power outages, which device should a user have in place?

• A. Battery backup
• B. Surge protector
• C. Voltage regulator
• D. Redundant server

Answer: (A)

To preserve data integrity during power outages, a battery backup, often referred to as an Uninterruptible Power Supply (UPS), is essential. This device provides temporary power to connected equipment during an outage, allowing systems to continue operating momentarily. More importantly, it gives users the opportunity to save their work and safely shut down devices without losing data, thus maintaining the integrity of the information stored on those devices. In contrast, while a surge protector helps shield equipment from voltage spikes, it does not provide backup power during outages. A voltage regulator stabilizes voltage levels to prevent fluctuations, but again, it does not offer any power protection during a complete power loss. A redundant server, while useful for ensuring availability and reliability in network environments, does not address the issue of immediate power failure for a single workstation or device. Therefore, the battery backup is critical for data preservation during unexpected power interruptions.
