Which power backup method will continually provide power to a server if the power goes out during a thunderstorm?
- a. Online UPS
- b. Generator
- c. Dual power supplies
- d. Standby UPS
When the power shut down due to thunderstorm the power back method used to provide power continuously is “online UPS”.
Hence, the correct answer is option “A”.
Explanation of Solution
UPS:
UPS is stands for Uninterruptible Power Supply. UPS is a processor of the computer system that is sensitive about electrical fluctuations.
- It is used for running the system for short time after stopping the power supply.
- It protects the system from the power surges.
Online UPS:
It provides power to the network device through its battery and it continuously uses AC power form the wall outlet to charge its battery.
- There is no risk in momentary power lapses as it constantly provides power from its inverter even when the power functions properly.
- It is more expensive than standby UPS.
Explanation for incorrect options:
Generator:
It is an electronic device used to generate different type of electronic waveforms of different range of frequencies.
Hence, the option “B” is wrong.
Dual power supplies:
- It is a common equipment’s in electronic circuits and to operate properly every circuits needs best power supply source...
