Which term describes a standby system that is not powered until failover is required?

Explanation:
Cold standby means the backup system sits powered off and isn’t in use until a failover is required. Because it’s kept offline, it costs less, uses less energy, and requires fewer resources to maintain. When the primary system fails, the cold standby is powered up, the necessary services are started, and data is brought in from backups or replicated storage. The trade-off is the time it takes to boot, initialize services, and catch the system up to current state, which means longer downtime compared with systems that are already running. In contrast, hot standby is already powered and ready to take over with minimal downtime, while warm standby is powered and partially prepared but may need some steps to become fully operational. Parallel standby involves two systems operating in tandem for load sharing or redundancy, which is more resource-intensive.
