A.Port security is implemented on the fa0/1 interface.
B.MAC address 0000.00aa.aaaa does not need to be learned by this switch.

D.Frames with a Layer 2 source address of 0000.00aa.aaaa will be forwarded out fa0/1.
E.MAC address 0000.00aa.aaaa will be listed in the MAC address table for interface fa0/1 only.

A.255.255.255.240
B.255.255.255.254
C.255.255.255.252
D.255.255.255.0
E.255.255.255.248

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.

A.微分割減小了網(wǎng)絡上的沖突次數(shù)。
B.如果交換機收到一個幀一個未知的目的地，它使用ARP解析地址。
C.生成樹協(xié)議允許交換機自動共享VLAN信息。
D.在一個功能正常的網(wǎng)絡冗余的交換路徑，每個交換環(huán)節(jié)將包含其轉(zhuǎn)發(fā)狀態(tài)的所有端口一個根橋。在廣播域中所有其它交換機將只有一個根端口。
E.建立的VLAN增加廣播域的數(shù)量。
F.配置有VLAN的交換機使基于第2層和第3層地址信息轉(zhuǎn)發(fā)決策。
