Jill wants to design her organization for high availability. Which of the following design elements best supports power resilience for a high-availability environment for an on-site datacenter?

Using UPS with generators will allow systems to remain online during a power outage even if the power outage extends for some time. Generators alone will not spin up fast enough to avoid an outage, and UPS systems will run out of battery power in extended outages. A warm site requires setup time to bring it online, resulting in an outage.
