Refer to the exhibit. How are new connections load balanced?
The correct answer is B. To the pool member with the least number of connections. Assuming a common load balancing method, new connections are distributed to the pool member with the least number of active connections.

Why each option
Assuming a common load balancing method, new connections are distributed to the pool member with the least number of active connections.
Load balancing typically employs specific algorithms to distribute traffic, not simply directing it to the first two members listed with the same priority group.
The 'Least Connections' load balancing method is a common and effective algorithm that directs new connections to the pool member currently processing the fewest active connections. This method ensures an even distribution of workload across available pool members within the active priority group, optimizing resource utilization.
Connections are directed to the highest available priority group, not specifically to a pool member based on a 'high priority group value' as the sole load balancing criteria within that group.
Connections are directed to the highest available priority group (typically represented by lower numerical values), not to a pool member with a low priority group value.
