F5CAB3: BIG-IP Administration Data Plane Configuration

QuestionQ6

Apply procedural concepts required to modify and manage virtual servers

A BIG-IP Administrator uses backend servers that host multiple services on each server. Multiple virtual servers and pools are configured that reference the same backend servers.

Which load-balancing algorithm is most suitable for maintaining an equal number of connections on every backend server?

Explanation

Least Connections (node) evaluates active connections for each backend node across the pool members that reference that node, so it directs new connections toward the backend server with the fewest current connections. Member-level methods count connections only for a specific pool member and can therefore fail to equalize totals when one server supports multiple services through several pools or virtual servers.
