Final answer:
In an A/A High Availability setup, whether traffic is directed to the primary device first depends on the configuration of the system, which can handle traffic concurrently in active-active mode, and traffic management determined by various controlling mechanisms.
Step-by-step explanation:
High Availability (HA) configurations are designed to provide continuous operational performance and minimize downtime. In an A/A High Availability setup, the answer to whether traffic is always directed to the primary device first is b) No, it depends on the configuration. Such systems can be configured in various ways, including active-passive or active-active modes. In active-active mode, both devices can handle the traffic concurrently rather than having a dedicated primary device that takes all the load initially. Traffic distribution is often controlled by load balancers or network configurations that can determine how the traffic is managed, ensuring availability even if one device fails.
Whether the traffic goes to a "primary" device may also be determined by load balancing algorithms, health checks, or priorities set within the HA configuration.
