Question 2

A generator would enable a data center to remain operational through a multiday power outage.

A generator provides a reliable source of power that can sustain operations for extended periods during outages, ensuring that critical systems remain functional.

A) Generator

A generator is specifically designed to provide power during outages, making it essential for maintaining operations in a data center. It can supply electricity for days, depending on the fuel supply, thus ensuring continuity even during prolonged power interruptions.

B) Uninterruptible power supply

An uninterruptible power supply (UPS) is primarily designed for short-term power outages, providing instant backup power for a limited duration. While it is crucial for protecting against brief interruptions, it would not sustain operations through a multiday outage, as it typically relies on batteries that can only last for a few hours or less.

C) Replication

Replication refers to the process of duplicating data across multiple locations to ensure data availability and disaster recovery. While it is essential for data integrity and availability, it does not directly address power supply issues or ensure continued operations during a power outage.

D) Parallel processing

Parallel processing involves using multiple processors or computers to perform tasks simultaneously, enhancing computational efficiency. However, it does not provide any solution for power outages, as it is entirely dependent on a stable power supply to function.

Conclusion

The generator is the only option that directly addresses the need for sustained power during a multiday outage, making it the best choice for maintaining data center operations. In contrast, the other options either provide limited power, focus on data protection rather than power supply, or do not relate to power management at all.
