You have just configured the network in the following exhibit. The commands you have entered configured the VLAN database and assigned the VLAN IDs to the interfaces. You cannot communicate between VLAN 2 and VLAN 4, but communication within VLAN 4 works. What is wrong?

A. The VLANs must be enabled via the command no shutdown.
B. The network requires routing between the VLANs.
C. The VLANs require VTP to be configured.
D. The interfaces are administratively shut down by default and need to be enabled via no shutdown.

B. When a VLAN is created, so is a broadcast domain. The broadcast domain/VLAN requires its own unique IP network addressing and a router to route between the networks.
