What feature allows multiple computers to quickly enter learning mode without individual configuration?

The feature that allows multiple computers to quickly enter learning mode without the need for individual configuration is the schedule maintenance button. This functionality streamlines the process by enabling an administrator to set a specific timeframe during which learning mode is activated for all designated machines simultaneously. This is particularly useful for managing multiple devices in an organization, as it reduces the administrative burden and ensures that the systems can be configured for learning mode at once, aligning with network maintenance schedules.

In contrast, the other options would require either manual configuration or do not focus specifically on the collective adjustment of settings across multiple devices, which makes them less efficient for this purpose. For instance, enabling learning mode individually necessitates logging into each computer separately, while utilizing batch processing and accessing the admin dashboard may not provide a direct or immediate means to initiate learning mode for multiple devices at once. Therefore, the scheduled maintenance capability is the most effective approach for configuring multiple systems in a unified manner.
