A.A more efficient use of bandwidth can be achieved allowing many physical groups to use the same network infrastructure
B.Broadcast storms can be mitigated by decreasing the number of broadcast domains,thus increasing their size.
C.A higher level of network security can be reached by separating sensitive data traffic from other network traffic.
D.Port-based vlans increase switch-port use efficient,thanks to 802.1Q trunks
