What are three benefits of implementing vlans?（）
- AA more efficient use of bandwidth can be achieved allowing many physical groups to use the same network infrastructure
- BBroadcast storms can be mitigated by decreasing the number of broadcast domains,thus increasing their size.
- CA higher level of network security can be reached by separating sensitive data traffic from other network traffic.
- DPort-based vlans increase switch-port use efficient,thanks to 802.1Q trunks
- EA more efficient use of bandwidth can be achieved allowing many logical networks to use the same network infrastructure.
- FBroadcast storms can be mitigated by increasing the number of broadcast domains,thus reducing their size.
- GVLANs make it easier for IT staff to configure new logical groups,because the vlans all belong to the same broadcast domain.
