Implementing Cisco IP Switched Networks (CCNP SWITCH, legacy) — Question 176

What attack technique attempts to fill a switching table so the attackers can capture traffic passing through a switch?

Answer options

• A. VLAN hopping
• B. MAC spoofing
• C. Rogue device
• D. MAC flooding D

Correct answer:

Explanation

The correct answer is D, MAC flooding, because this technique overwhelms the switch's MAC address table, causing it to fail open and forward all traffic to all ports. VLAN hopping (A) and MAC spoofing (B) do not specifically target the switch's MAC table, while a rogue device (C) refers to unauthorized hardware on the network rather than a flooding technique.
