Which statement accurately describes the difference between two loadbalancing modes specified as "member" and "node".

The 'node' and 'member' variants represent fundamentally different scopes of metric measurement and are not backward-compatibility aliases for the same behavior.

Priority group activation is governed by the priority group settings on pool members and is not restricted or unavailable based on whether the load balancing mode references 'node' or 'member'.

Node-based load balancing options are not limited to any particular pool member configuration type - they are available regardless of how pool members are defined.

When the load balancing choice references 'node', the BIG-IP evaluates the node address parameters - such as total current connections or response time - aggregated across every pool that server IP belongs to when selecting a destination. This differs from 'member' mode, which evaluates only the metrics scoped to that pool member's participation in the specific pool being load balanced.
