On a corporate network, hosts on the same VLAN can communicate with each other, but they are unable to communicate with hosts on different VLANs. What is needed to allow communication between the VLANs?

a router with subinterfaces configured on the physical interface that is connected to the switch
a router with an IP address on the physical interface connected to the switch
a switch with an access link that is configured between the switches
a switch with a trunk link that is configured between the switches

Answer(s): A

Explanation:

Different VLANs can't communicate with each other, they can communicate with the help of Layer3 router. Hence, it is needed to connect a router to a switch, then make the sub-interface on the router to connect to the switch, establishing Trunking links to achieve communications of devices which belong to different VLANs.
