In a redundant network setup, how do the primary and secondary networks operate?

In a redundant network setup, it is crucial for the primary and secondary networks to maintain operational reliability and fault tolerance. The correct answer indicates that they operate full time in separate broadcast domains. This configuration allows for the separation of traffic between the primary and secondary networks, ensuring that if one network experiences failure, the other can take over without experiencing the same issues.

By having distinct broadcast domains, the networks can effectively manage network traffic and avoid potential collisions or interference that might arise if both networks were to communicate within the same broadcast domain. This operational separation enhances the reliability of the overall network, allowing for seamless switchover and reducing the chances of having both networks fail simultaneously due to interference or misconfiguration.

The incorrect options imply either a lack of separation between the networks or suggest that both are always communicating or connected, which would not adhere to best practices for creating a robust redundant network. Ensuring that the primary and secondary networks are isolated from each other is a foundational principle for achieving optimal redundancy and operational efficiency.
