Under what circumstances should an administrator prefer local VLANs over end-to-end VLANs?
A.
Eighty percent of traffic on the network is destined for Internet sites.
B.
There are common sets of traffic filtering requirements for workgroups located in multiple buildings.
C.
Eighty percent of a workgroup’s traffic is to the workgroup’s own local server.
D.
Users are grouped into VLANs independent of physical location.
Explanation:
This geographic location can be as large as an entire building or as small as a single switch inside a wiring closet. In a geographic VLAN structure, it is typical to find 80 percent of the traffic remote to the user (server farms and so on) and 20 percent of the traffic local to the user (local server, printers, and so on).
