300-115 题库V2.0 关于stack, vlan等题目请教

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。

拖图题，配对后结果如下

Waiting = The stack master is actively performed discovery

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：
' }- Q6 M: r5 ]# e( L& ?  b0 Ehttps://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"
2 @+ U5 G' a0 [- i
$ b9 s! W1 a9 O; P& f3 O7 PProvisioned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.

Provisioned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。

2. 实验题第一题AAA的配置
我这边模拟器上面的交换机似乎不支持802.1x的配置，请大家都怎么练习下面相关的命令的？
比如全局配置模式下：
0 E. w2 _# k7 v4 y# O& D/ qaaa authentication dot1x default group radius
dot1x system-auth-control
2 Y0 M1 F. b3 h) Y; N端口模式下：
" h+ [- ~- T- l4 }! F) }/ }dot1x port-control auto

我认为是ox88a8，答案A是最接近的，大家怎么看？

第一题答案文档里面就有。

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.

The Provisioned state might be caused by a switch that is no longer connected to the stack or be the result of manually preprovisioning the related ports. See the Catalyst 3750 or the Catalyst 3750-E switch software configuration guide for more information on preprovisioning switches in a stack.

Provisoned状态原因有两个，一个是之前是stack一部分的一台交换机被移除或掉线；或者是之前有手动配置。一般来说，堆叠设备型号相同是不需要手动配置。

手动配置方式参考：https://www.cisco.com/c/en/us/td ... tack.html#wp1177470

2. 我用GNS3+IOU  可以配AAA的命令，dot1x port-control auto 是隐藏命令，不能用？的，不过全打出来是可以的，后面 vlan ACL 都不支持。只能默默背下来
