CCNP(300-115)题库V2.0（2017.8.21）中有3个小问题请教大家。先谢谢了。

9 I  n# X; ^( V. V, B/ n+ r7 e! \我想对这些状态排序以便更好的理解，于是参考了如下链接：
( V2 f# C+ g/ F! Uhttps://www.cisco.com/c/en/us/td ... /switch_stacks.html

当交换机加入堆叠时候，状态变化的顺序为"Waiting-> Progressing-> Initializing-> Ready"
8 w* e" a# ]' c5 h! k
Provisioned的详细定义如下：
Provisioned: Ports are assigned in the stack running-configuration, but no switch with the port numbers Fa3/0/1, G3/0/1, and so on, is detected in the stack. If a switch that previously joined a stack is removed, the port numbers remain in the running-configuration, and the missing switch is shown as Provisioned.

5 y: A  Z! J4 X# {- M( vProvisioned在Progressing之后，任何时候都会发生，是一种非正常的状态呢？

请问我的以上理解正确吗？欢迎指正，谢谢。
