E. They act as though they are on the same LAN regardless of physical location.
Correct Answer: BCE
Explanation/Reference:
VLANs provide the following advantages:
* (E) VLANs enable logical grouping of end-stations that are physically dispersed on a network. …
* VLANs reduce the need to have routers deployed on a network to contain broadcast traffic. …
* (C) Confinement of broadcast domains on a network significantly reduces traffic.
By confining the broadcast domains, end-stations on a VLAN are prevented from listening to or receiving broadcasts not intended for them.
* (B) If a router is not connected between the VLANs, the end-stations of a VLAN cannot communicate with the end-stations of the other VLANs.
