Select the 2 best answers.


Answer: A, C
As networks grow in size and complexity, many companies turn to Virtual Local Area Networks (VLANs) to provide some way to structure this growth logically. Basically, a VLAN is a collection of nodes that group together in a single broadcast domain. The basis for the group is something other than physical location. The section Switch Technologies describes broadcasts and how a router does not pass along broadcasts. A broadcast domain is a network or portion of a network that receives a broadcast packet from any node within that network. In a typical network, everything on the same side of the router is part of the same broadcast domain. A switch on which you have implemented VLANs now has multiple broadcast domains, which is similar to a router. But you still need a router to route from one VLAN to another. The switch alone cannot perform this routing.
