Which of the following would enable a data center to remain operational through a multiday power outage?

While uninterruptible power supplies (UPS) are valuable for providing short-term power backup and protection against power fluctuations, they are not typically designed to support a data center through multiday power outages. UPS systems offer temporary power until generators or alternative power sources can be activated.

Replication involves duplicating data and systems across multiple locations to ensure redundancy and availability. While replication is crucial for data protection and disaster recovery, it does not directly address the power supply issue during a multiday outage. It helps in maintaining data integrity and accessibility but does not provide power to the data center.

Parallel processing involves breaking down computational tasks into smaller parts that can be executed simultaneously, improving efficiency and speed. While it enhances performance in data processing, it does not contribute to keeping a data center operational during a power outage. Parallel processing focuses on optimizing computing resources rather than power continuity.
