網(wǎng)絡(luò)管理員在交換機(jī)1上創(chuàng)建一個(gè)新VLAN并且將主機(jī)C和主機(jī)D加入到此VLAN中。管理員配置交換機(jī)接口FastEthernet0/13到FastEthernet0/24成為新VLAN成員.但是網(wǎng)絡(luò)管理員完成配置以后,主機(jī)A可以和主機(jī)B通信,但是主機(jī)A不能和主機(jī)C或者主機(jī)D通信。哪個(gè)命令可以用來(lái)解決這個(gè)問(wèn)題?()
A.
B.
C.
D.
A.Only passwords configured after the command has been entered will beencrypted.
B.Only the enable password will be encrypted.
C.Only the enable secret password will beencrypted
D.It will encrypt the secret password and remove the enable secret password from the configuration.
E.It will encrypt all current and future passwords.
A.Security increases because only the network administrator may change the routing tables.
