A hot standby system is defined by its readiness for immediate operation, which is precisely why the correct answer emphasizes that a backup machine is always prepared to take over without delay. In such configurations, the standby system runs concurrently with the primary system, continuously receiving updates and mirroring its operations. This capability ensures that in the event of a failure in the primary system, there is no downtime, allowing for seamless transition and continued service. Options that suggest a backup machine being powered off until needed or requiring monthly updates demonstrate a lack of immediacy and readiness, which are not characteristic of a hot standby system. Similarly, a configuration requiring extensive setup before activation does not align with the concept of a hot standby, where the emphasis is on instant accessibility and operation without the need for reconfiguration.
