When a secondary network in a redundant setup is dormant, under what condition does it activate?

In a redundant network setup, the secondary network is designed to serve as a backup that activates only when needed. The key function of this secondary network is to ensure that audio and data can continue to flow seamlessly in case of a failure in the primary network.

When a failure occurs in the primary network, the secondary network detects that the primary system is no longer operational, which triggers the activation of the backup system. This mechanism is essential for maintaining reliability and minimizing downtime, particularly in critical applications such as live sound or broadcasting where uninterrupted service is paramount.

Options that highlight full capacity operation or scheduled intervals do not accurately reflect the primary purpose of a redundant system, which is reactive rather than proactive in its activation. Thus, the condition that leads to the activation of the dormant secondary network is an explicit failure in the primary network, allowing for a swift transition to maintain network integrity and communication.
