B. Broadcast storms can be mitigated by decreasing the number of broadcast domains,thus increasing
C. A higher level of network security can be reached by separating sensitive data traffic from other network
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
F. Broadcast storms can be mitigated by increasing the number of broadcast domains,thus reducing their
G. VLANs make it easier for IT staff to configure new logical groups,because the vlans all belong to the
same broadcast domain.
D thanks to 802.1Q trunks不正确
In the implementation of VLSM techniques on a network using a single Class C IP address,which subnet
mask is the most efficient for point-to-point serial links?
A switch has been configured with two vlans and is connected to a router with a trunk for inter-vlan routing.
OSPF has been configured on the router,as the routing protocol for the network.Which statement about this
network is true?
A. For the two vlans to communicate,a network statement for the trunk interface needs to be added to the
B. For the two vlans to communicate,a network statement for each subinterface needs to be added to the
C. Direct inter-vlan communication does not require OSPF.
D. OSPF cannot be used if router-on-a-stick is configured on the router.
