What happens when the bandwidth limit is exceeded on the X1 interface?

When the bandwidth limit is exceeded on the X1 interface, traffic is typically rerouted to alternative WAN interfaces. This mechanism is often part of load balancing or failover configurations, where the device redirects traffic in a round robin manner across the available WAN interfaces. The primary aim is to maintain connectivity and distribute the network load evenly, ensuring that no single interface becomes a bottleneck while adhering to bandwidth limitations.

In many network configurations, this capability allows for improved performance and redundancy. If one interface becomes congested or reaches its bandwidth threshold, users experience less disruption as the system actively seeks to utilize alternate pathways for data transmission.

The other choices reflect different behaviors that may not accurately describe the functionality of bandwidth limit management on the X1 interface. For example, traffic prioritization would typically involve Quality of Service (QoS) mechanisms rather than rerouting. Blocking all traffic or queuing it until bandwidth becomes available does not align with the proactive approach to handling bandwidth limits effectively.
