An attacker has connected to an unused VoIP phone port to gain unauthorized access to a network.
This is an example of which of the following attacks?
A . Smurf attack
B . VLAN hopping
C . Bluesnarfing
D . Spear phishing
Answer: B
Explanation:
The VoIP phone port can be used to attack a VLAN on the local network.
