Which statement best describes an active-passive configuration?

1. Both devices are functional simultaneously

2. One device is in standby mode while the other operates

3. Both devices require constant manual input

4. Neither device is actively processing data

The correct answer is: One device is in standby mode while the other operates

An active-passive configuration is characterized by one device actively handling all the workload while the other device remains in a standby state, ready to take over if the primary device fails or experiences issues. This approach is commonly used in systems that prioritize reliability and uptime, ensuring that there is always a backup available to minimize downtime. In this configuration, the active device processes all data and requests, while the passive device monitors the active one. If the active device fails, the passive device can quickly switch to an active role, allowing for a seamless transition and continued service without significant interruption. This is different from an active-active configuration, where both devices operate simultaneously to share the workload, enhancing performance and redundancy. The other options do not accurately describe an active-passive setup. For instance, the idea of both devices functioning at the same time contrasts with the fundamental definition of the active-passive model, where only one device is actively engaged. Constant manual input contradicts the automated failover and redundancy features intended by an active-passive configuration, while neither device processing data does not apply since one device is actively handling tasks. Thus, the chosen statement accurately reflects the essence of an active-passive configuration.
