The Company network needs to pass traffic between VLANs. Which device should be used
to accomplish this?

A.
Hub

B.
Switch

C.
Router

D.
Bridge

E.
None of the other alternatives apply

Explanation:
A VLAN is a virtual LAN contained within a switch, so for it to pass information into a
different VLAN within the same switch it has to leave that switch and re-enter via a router.
VLANs contain local traffic only, so in order to reach users in another VLAN the traffic must
go through a router or a layer 3 routing processor.
