56. Which of the following is the best safeguard to protect against an extended power failure?

Answer: D

Explanation:

Generators are the best safeguard to protect against an extended power failure.

Generators provide a reliable source of power during prolonged outages, ensuring that essential systems and equipment remain operational.

A) Off-site backups

Off-site backups are crucial for data protection but do not provide immediate power supply during an outage. They primarily safeguard data rather than maintaining operational capability during a power failure.

B) Batteries

While batteries can offer temporary power solutions, they typically have limited capacity and duration. They may not sustain operations for extended periods, making them insufficient for long-term power failures.

C) Uninterruptible power supplies

Uninterruptible power supplies (UPS) offer short-term backup power and protect against surges, but they are designed for brief outages. They cannot provide the extended power necessary during prolonged outages, which limits their effectiveness.

D) Generators

Generators are designed to provide power for extended periods, making them the most effective safeguard against prolonged power failures. They can keep critical systems running until normal power is restored.

Conclusion

Generators stand out as the most effective solution for extended power failures because they can deliver sustained power when other options, such as batteries and UPS systems, fail to meet the demand. Other options primarily address short-term needs or data protection rather than ensuring continuous operational capacity.
