Which statement accurately describes the difference between two loadbalancing modes specified as "member" and "node"?
A.
There is no difference; the two terms are referenced for backward compatibility purposes.
B.
When the loadbalancing choice references "node", priority group activation is unavailable.
C.
Loadbalancing options referencing "nodes" are available only when the pool members are defined for the "any" port.
D.
When the loadbalancing choice references "node", the addresses' parameters are used to make the loadbalancing choice rather than the member's parameters.
D. When the loadbalancing choice references "node", the addresses' parameters are used to make the loadbalancing choice rather than the member's parameters.: In load balancing modes that reference "node," the decision is based on the node's IP address parameters. This means that the load balancing algorithm considers the overall usage of the node's IP address across all ports. In contrast, when the load balancing mode references "member," it considers the specific IP address and port combination (the pool member), thus making decisions based on the individual service on that node.
D. When the loadbalancing choice references "node", the addresses' parameters are used to make the loadbalancing choice rather than the member's parameters.
Here’s the reasoning:
"Member" in F5 load balancing refers to the individual server or machine in the pool, and the load balancing decision is based on the parameters specific to the member itself (such as the health, connections, or other member-specific metrics).
"Node" refers to the IP address of the server, without considering individual port-level details. When you reference a "node" for load balancing, F5 will make the decision based on the node's parameters (like its IP address), not the specific ports or services (members) tied to that node.
