A virtual server is defined using a source address based persistence profile. The last five
connections were A, B, C, A, C . Given the conditions shown in the graphic, if a client with IP
address 205.12.45.52 opens a connection to the virtual server, which member will be used
for the connection?

A. 10.10.20.1:80
B. 10.10.20.2:80
C. 10.10.20.3:80
D. 10.10.20.4:80
E. 10.10.20.5:80
Answer: B

按照最小连接数的负载均衡算法，不应该选择E吗，请教一下各位大神

这三道同类型的题我实在看不出怎么得出的答案，是题库的答案有问题还是怎么回事，求各位指导下

又来一道 答案给的是d，到底为什么

这样的题很简单，先看保持类型，再看状态，然后看优先级活跃数量，再看最小连接数

dododuck1977

先看会话保持类型（源地址，cookie等），再看状态（disable,offline等），然后看优先级活跃数量（member ratio  priority等），再看最小连接数
Q174, 源地址会话保持， 195.64.45.52转发至10.10.20.3：80，虽然10.101.20.3状态是disable, 不会转发新conn,还是会转发旧conn, 所以下一个连接还是转发10.10.20.3：80
其它问 看member ratio  priority 即可所知

还要看会话保持的timeout
