What is the default behavior for traffic load balancing in A/A HA configurations?

In an Active/Active (A/A) High Availability (HA) configuration, the default behavior for traffic load balancing is such that the system is designed to handle traffic across all active instances. This means that by default, traffic is load balanced, allowing multiple nodes to simultaneously process requests. This effectively utilizes resources across the available servers, enhancing both performance and redundancy in the system.

This behavior is crucial in A/A configurations because it ensures that no single node becomes a bottleneck in performance and that the workload is distributed evenly across all active nodes. By doing so, A/A configurations can provide better efficiency and response times for users, as multiple resources are engaged in handling the incoming requests. This distributed model also increases fault tolerance since even if one node goes down, the remaining nodes can continue to handle traffic without a significant impact on service availability or performance.

The other options do not accurately capture the characteristics of A/A configurations, which inherently support traffic balancing among active nodes.
