Certified Ethical Hacker (CEH) Practice Question

While analyzing switch port mirroring logs, you notice host 52:54:00:ab:cd:ef repeatedly sending unsolicited ARP reply packets that state "192.168.50.1 is-at 52:54:00:ab:cd:ef," even though the legitimate default gateway has MAC 00:25:90:12:34:56. Shortly afterward, several workstations begin routing their traffic through the rogue host. Which sniffing-related spoofing technique is the attacker using to redirect the traffic?

  • MAC flooding to overflow the switch's CAM table

  • DHCP spoofing to issue fraudulent default-gateway information

  • DNS cache poisoning to redirect hostname lookups

  • ARP poisoning (ARP spoofing) to perform a man-in-the-middle attack
