You are working as a technician at certifyme.com. You are asked to prepare a couple
of workstations to be used in an electrically unstable environment where brownouts
are a regular occurrence.70-290 Which of the following would be the BEST solution in
order to protect the workstations?
A. an uninterruptible power supply (UPS)
B. a surge protector
C. a power strip
D. an anti-static pad
Answer: A
Explanation: Brownout is where the voltage level is below the normal minimum
level specified for the system.70-551 Systems supplied with three-phase electric power also
suffer brownouts if one or more phases are absent. UPS would protect against this
as it will even out any fluctuations in the voltage level.
