Where is the loadbalancing mode specified.

The load balancing mode (or method) is a fundamental property of a pool, determining the algorithm the load balancer uses to distribute incoming client connections across the pool's members (backend servers).

The node definition primarily specifies the IP address and basic attributes of a backend server, not the algorithm for traffic distribution.

A virtual server acts as a listener for incoming traffic and directs it to a pool, but the specific load balancing algorithm is defined within the referenced pool, not the virtual server itself.

A pool member definition specifies a particular server within a pool and its specific properties like ratio or connection limits, but it does not define the overall load balancing method for the entire pool.
