Which of the following best describes the action of implementing a Spillover Failover/Load-balance?

Implementing a Spillover Failover/Load-balance involves connecting new traffic to an alternate WAN when limits on the primary WAN are reached. This method helps manage traffic efficiently by ensuring that when one connection reaches its capacity or experiences issues, additional traffic is automatically routed to a secondary WAN connection to maintain performance and reliability.

This approach not only provides continuity in service during high traffic periods but also optimizes the use of available WAN resources. It is particularly beneficial in environments where bandwidth demand can fluctuate significantly, allowing organizations to sustain operations without interruptions due to network congestion.

The other options, while they may refer to aspects of network management, do not accurately capture the specific function of Spillover Failover/Load-balance. For instance, distributing load evenly among all interfaces refers more to load balancing rather than failover; shifting traffic only to the fastest WAN suggests a preference that overlooks the need for backup connections; allocating traffic based on user schedules does not relate to the immediate response to congestion or system limits. Thus, the focus on connecting to an alternate WAN after limits are reached encapsulates the essence of spillover functionality effectively.
