The Ezonexam network Topology is displayed in the exhibit below:

A switch has been configured for three different VLANs: VLAN 2, VLAN 3, and VLAN 4. For the purposes of communication between VLANs a router is to be added. Host from one VLAN should be able to reach the hosts in the other VLANs.

Based on this requirement, what type of connection is acceptable between the router and switch？

(Select all valid answers)

A．10 Mbps Ethernet

B．56 kbps serial

C．100 Mbps Ethernet

D．1,544 Mbps serial

E．1000 Mbps Ethernet

D.This switch has a lower bridge ID for VLAN 2 than the elected designated switch.

A.The switch will not forward unicast frames.

B.The switch will forward the frame to a specific port.

C.The switch will return a copy of the frame out the source port.
