Which of the following attacks involves an attacker tricking a network switch into believing the attacker’s host is another switch, allowing access to traffic from multiple VLANs?
Correct Answer: A
VLAN hopping occurs when an attacker tricks a switch into believing the host is another switch by generating tagged frames or exploiting trunk negotiation (DTP). This allows the attacker to access traffic from multiple VLANs, potentially stealing sensitive data.
* B. Evil twin is a rogue wireless AP attack, unrelated to switch impersonation.
* C. DNS poisoning corrupts name resolution, not VLAN access.
* D. ARP spoofing is a Layer 2 on-path attack, not masquerading as a switch.
