Which feature on a switch makes it vulnerable to VLAN hopping attacks?
- the mixed duplex mode enabled for all ports by default
- the limited size of content-addressable memory space
- mixed port bandwidth support enabled for all ports by default
- the automatic trunking port feature enabled for all ports by default
Answers Explanation & Hints:
A VLAN hopping attack enables traffic from one VLAN to be seen by another VLAN without routing. In a basic VLAN hopping attack, the attacker takes advantage of the automatic trunking port feature enabled by default on most switch ports. |
