Which three statements accurately describe layer 2 Ethernet switches？（）
A
Microsegmentation decreases the number of collisions on the network.
B
if a switch receives a frame for an unkown destination，it uses ARP to resolve the address.
C
Spanning Tree Protocol allows switches to automatically share vlan information.
D
In a properly functioning network with redundant switched paths，each swiched aegment will contain oneroot bridge with all its ports in the forwarding state.All other switches in that broadcast domain will haveonly one root port.
E
Establishing vlans increases the number of broadcast domains.
F
Switches that are configured with vlans make forwarding decisions based on both layer 2 and layer 3address information.
