CompTIA Security+ (SY0-601) — Question 422

A large bank with two geographically dispersed data centers is concerned about major power disruptions at both locations. Every day each location experiences very brief outages that last for a few seconds. However, during the summer a high risk of intentional under-voltage events that could last up to an hour exists, particularly at one of the locations near an industrial smelter. Which of the following is the best solution to reduce the risk of data loss?

Answer options

• A. Dual supply
• B. Generator
• C. PDU
• D. Daily backups

Correct answer: B

Explanation

The best solution is a Generator, as it can provide backup power during prolonged outages, such as the potential under-voltage events mentioned. A Dual supply may help with minor outages but won't suffice for extended power loss. A PDU (Power Distribution Unit) manages power but does not generate it, and while Daily backups are crucial for data protection, they do not prevent data loss during power disruptions.
