What factor contributes to increased network availability?

Implementing proper network redundancy is a critical factor for increasing network availability. Redundancy involves having additional or duplicate components or systems in place that can take over seamlessly in case of a failure. By having multiple pathways for data to travel within a network, or backup systems ready to take charge in the event of a failure, the risk of downtime is significantly reduced. This means that even if one part of the network experiences a failure, other parts can continue to operate normally, ensuring that the network remains accessible to users.

In contrast, using a single path for data transfer increases the risk of outages, as there are no alternative routes for data if that path fails. Limiting the number of devices can lead to more manageable network operations but doesn't necessarily enhance availability; in fact, it can hinder growth and flexibility. Reducing data transfer rates might help manage congestion but could negatively impact performance and user experience. Thus, proper network redundancy is the most effective approach in enhancing network availability.
