67. Which of the following can be deployed in data centers as a protection against an undervoltage event?
Answer: D
Uninterruptable power supply
An uninterruptable power supply (UPS) can be deployed in data centers as a protection against an undervoltage event. It provides backup power and stabilizes voltage levels to ensure continuous operation of critical equipment during power disturbances.
A) Resource management
Resource management refers to the strategy of allocating and utilizing resources effectively within an organization. While it is crucial for operational efficiency, it does not directly protect against undervoltage events in data centers.
B) Load balancer
A load balancer distributes network or application traffic across multiple servers to optimize resource use and prevent overload. However, it does not offer any protection against undervoltage conditions affecting power supply.
C) Surge protector
A surge protector is designed to prevent damage from voltage spikes by diverting excess voltage away from connected devices. Although it protects against surges, it does not specifically address the issue of undervoltage, which requires a different solution.
D) Uninterruptable power supply
An uninterruptable power supply (UPS) is specifically designed to provide emergency power and maintain voltage levels during undervoltage events. It ensures that devices remain operational and protected from power quality issues, making it the appropriate choice for data centers facing undervoltage risks.
Conclusion
The uninterruptable power supply is definitively the correct answer as it is specifically designed to combat undervoltage events, ensuring that critical systems remain powered and stable. All other options either do not directly address power quality issues or serve different purposes within a data center environment.
