A BIG-IP Administrator is configuring a pool with members who have differing capabilities. Connections to pool members must be load balanced appropriately. Which load balancing method should the BIG-I

The correct answer is D. Weighted Least Connections (member). For pool members with differing capabilities, the Weighted Least Connections (member) load balancing method should be used to distribute connections appropriately.

Why each option

For pool members with differing capabilities, the Weighted Least Connections (member) load balancing method should be used to distribute connections appropriately.

ALeast Sessions

Least Sessions distributes new connections to the member with the fewest active sessions, but it does not account for differing processing capabilities or capacities between members.

BLeast Connections (member)

Least Connections (member) directs new connections to the member with the fewest active connections, without considering any inherent differences in processing power among the pool members.

CFastest (node)

Fastest (node) sends connections to the node that responds fastest to health monitor probes, which may not accurately reflect its sustained capability to handle application traffic.

DWeighted Least Connections (member)Correct

Weighted Least Connections (member) allows the administrator to assign a weight to each pool member, ensuring that members with higher capabilities receive a proportionally larger share of new connections while still minimizing connections to already busy members.
