正确答案及解析
正确答案
A
解析
试题分析：
要实现上图中跨交换机的Vlan之间的通信，需要配置SwitchA和SwitchB之间的链路类型及通过的VLAN，实现相同业务用户通过SwitchA和SwitchB通信。
[SwitchA] interface gigabitethernet 1/0/3
[SwitchA-GigabitEthernet1/0/3] port link-type trunk //交换机之间相连接口类型建议使用trunk，接口
默认类型不是trunk，需要手动配置为trunk
[SwitchA-GigabitEthernet1/0/3] port trunk allow-pass vlan 2 3 //将接口GE1/0/3加入VLAN 2和VLAN 3
