看到分享的文档，里面有几道争议题，跟题库不太一样，求考完的大神帮忙看看是选哪项
1、When you enable port security on an interface that is also configured with a voice VLAN, what is the
maximum number of secure MAC addresses that should be set on the port?
A. No more than one secure MAC address should be set.
B. The default is set.
C. The IP phone should use a dedicated port, therefore only one MAC address is needed per port.

选A还是B？

恰巧还都知道些，第一个是选b的，端口安全是一个vlan对于一白名单，题目问的是有两个vlan （数据vlan和语音vlan），也就是有两白名单，所以就是b
第二个是abde
lacp实验要在sa上show看vtp和stp的模式，
