- D UPS
Reveal correct answer
Correct answer: D
Explanation
Correct Answer:
D is correct. An uninterruptible power supply (UPS) is a temporary power source intended to be a backup supply in the event of a power failure; thus, it does not address Jonathan’s ongoing problem of line noise.
Incorrect Answers:
A is incorrect. A voltage regulator can extract momentary extra line voltages to protect his system and data.
B is incorrect. A line conditioner uses a tap to look for lows and highs in voltage and compensates for them.
C is incorrect. What he really needs to do is move the cords and cables to other outlets to reduce line noise and the threat of fire—this is the least expensive solution.
