Implementing Cisco Network Security (IINS, legacy) — Question 64

What are the primary attack methods of VLAN hopping? (Choose two)

Answer options

• A. VoIP hopping
• B. CAM-table overflow
• C. Switch spoofing

Correct answer:

Explanation

The correct answers are B. CAM-table overflow and C. Switch spoofing. CAM-table overflow allows an attacker to send a flood of MAC addresses to the switch, causing it to fail open and forward packets between VLANs. Switch spoofing involves tricking the switch into thinking the attacker is also a switch, allowing them to send traffic between VLANs improperly.
