Selected Answer: B

I did that in a lab - it is B. The reason is that once member 4 goes offline, persistance records are removed, so it will not go to disabled member, but per prio group 5 and least connections LB which in this case is B

Selected Answer: B

Not 100% sure but by default it would be load balanced to .4 but it is offline. .3 is disabled. Priority is 5:1 for .1 and .2, and according to the # of connections it should still go to either .1 or .2. 10.10.20.2 has less connecitons so according to the least connections setting it will go to .2.

I was wrong. IP is 205.12.45.52, mask is 255.255.0.0. Persistence timeout is 360s, upper table shows that the connection is connected to the pool member for 300s. Pool member .3 may be disabled but persistent connections still go through it. Therefore i would choose node 10.10.20.3.
