22 / 65

Which three statements accurately describe Layer 2 Ethernet switches? (Choose three.)

Spanning Tree Protocol allows switches to automatically share VLAN information.

Establishing VLANs increases the number of broadcast domains.

Switches that are configured with VLANs make forwarding decisions based on both Layer 2 and Layer 3 address information.

In a properly functioning network with redundant switched paths, each switched segment will contain one root bridge with all its ports in the forwarding state. All other switches in that broadcast domain will have only one root port.

If a switch receives a frame for an unknown destination, it uses ARP to resolve the address.
