Certified Ethical Hacker (CEH v13) — Question 209

Which type of attack attempts to overflow the content-addressable memory (CAM) table in an Ethernet switch?

Answer options

• A. DDoS attack
• B. Evil twin attack
• C. DNS cache flooding
• D. MAC flooding

Correct answer: D

Explanation

The correct answer is D, MAC flooding, which specifically targets the CAM table by sending numerous MAC addresses to fill it up, causing legitimate traffic to be dropped. A DDoS attack (A) aims to overwhelm a network with traffic but does not specifically target the CAM table. An Evil twin attack (B) involves creating a fake access point to capture data, while DNS cache flooding (C) focuses on disrupting DNS services, neither of which relate to CAM table overflow.
