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 E . A more efficient use of bandwidth can be achieved allowing many logical networks to use the same network infrastructure. F . Broadcast storms can be mitigated by increasing the number of broadcast domains,thus reducing their size. G . VLANs make it easier for IT staff to configure new logical groups,because the vlans all belong to the same broadcast domain.
