ISC2 Certified in Cybersecurity (CC) Practice Question
Within an on-premises data center, which control is designed to deliver instantaneous, short-duration electrical power when utility supply is lost, allowing critical equipment to remain online until backup generators engage?
Heating, ventilation, and air-conditioning (HVAC) system
An uninterruptible power supply (UPS) contains batteries or other energy-storage components that immediately provide power when the primary utility source fails. This short bridge keeps servers and network devices running long enough for standby generators to start and stabilize. HVAC units regulate temperature and humidity but do not supply power. A dry pipe sprinkler system is a fire-suppression measure, and a raised floor primarily aids cable management and airflow; neither delivers backup electricity.
