What is a method to launch a VLAN hopping attack?
- introducing a rogue switch and enabling trunking
- sending spoofed native VLAN information
- sending spoofed IP addresses from the attacking host
- flooding the switch with MAC addresses
Explanation: A VLAN hopping attack enables traffic from one VLAN to be seen by another without the aid of a router by configuring a host or rogue switch to spoof Dynamic Trunking Protocol (DTP) signaling, which exploits switch ports that have the automatic trunking feature enabled by default to establish an unauthorized trunk link and grant the attacker access to all VLANs on the switch.
