220-1102 · Question #681

A location is experiencing under-voltage events during peak periods. Which of the following should be deployed at this location?

The correct answer is B. UPS. A UPS (Uninterruptible Power Supply) is designed to provide stable power and battery backup, making it ideal for protecting equipment from under-voltage events (sags or brownouts).

Why each option

A UPS (Uninterruptible Power Supply) is designed to provide stable power and battery backup, making it ideal for protecting equipment from under-voltage events (sags or brownouts).

AProper ventilation

Proper ventilation addresses heat dissipation, not power quality issues like under-voltage.

BUPSCorrect

A UPS (Uninterruptible Power Supply) includes battery backup and often voltage regulation features (like AVR - Automatic Voltage Regulation) that can stabilize incoming power, protecting connected devices from under-voltage events by either boosting the voltage or switching to battery power. This ensures consistent power delivery during sags or brownouts.

CSurge protector

A surge protector guards against voltage spikes (over-voltage), not under-voltage events.

DPDU

A PDU (Power Distribution Unit) distributes power to multiple devices but does not provide voltage regulation or battery backup for under-voltage events.
