问题 There are 2 switches in the Ezonexam LAN, with no routers. Ports 1, 2 & 3 are assigned to VLAN 1 in switch 1 and 2 and ports 4, 5 & 6 are assigned to VLAN 2 in both switches. These two switches are connected together via a trunked link. Which of the conditions below would verify trunk and VLAN operation? (Select all valid answers)

选项 A、Host 1 on VLAN 1 can ping Host 2 on VLAN 1
B、Host 1 on VLAN 1 can ping Host 4 on VLAN 2
C、Host 1 on VLAN 1 can not ping Host 2 on VLAN 1
D、Host 4 on VLAN 2 can not ping Host 1 on VLAN 1
E、Host 4 on VLAN 2 can ping Host 2 on VLAN 2

答案A,D,E

解析 Explanation:
If there is no router present, only hosts in the same VLAN will be able to ping each other. In order for any host on one VLAN to communicate with a host on another VLAN, the traffic must pass through a router. Host within the same VLAN will be able to ping each other, even though they reside on different switches, as long as the switches have a trunk connection configured between them.
