Danielle’s organization has experienced a total power outage. The datacenter is currently running on its UPS. What concern should Danielle have if the UPS is her organization’s only power resilience control?
Answer Options
The generator may not start.
The UPS batteries may run out before the outage is over.
The generator may run out of fuel in a long outage.
The UPS may not handle the surge when power resumes.
Correct Answer: B
Explanation
Organizations typically deploy both a UPS and a generator (or generators!). Long power outages will drain the batteries that a UPS relies on. Since UPS systems are typically intended to run for minutes, rather than hours, for datacenters this should be Danielle’s first concern. No generator was mentioned, and in fact the UPS is her only power resilience control. While a UPS may experience issues with surges when power resumes, temporary drops in voltage, and power outages are not uncommon even on well-maintained power grids, and UPS systems are designed to handle them under normal circumstances while protecting the systems they provide emergency power to.
