After a security incident, a technician reveals that company data was stolen. During the investigation, it is discovered that a host disguised itself as a switch. Which of the following best describes the attack that occurred?

VLAN hopping involves an attacker gaining access to a virtual LAN (VLAN) by exploiting vulnerabilities in the network configuration, typically through double tagging or misconfiguration of VLAN tagging protocols. However, this attack does not specifically involve masquerading as a switch or intercepting traffic in the manner described in the question.

An evil twin attack occurs when a rogue access point mimics a legitimate Wi-Fi hotspot, tricking users into connecting to it. While this attack involves deception, it primarily targets wireless networks and does not relate to the scenario of a host disguising itself as a switch within a wired network environment.

DNS poisoning, or DNS spoofing, involves corrupting the DNS cache to redirect users from legitimate sites to malicious ones. This attack affects domain name resolution but does not involve disguising as network hardware or intercepting local traffic, which is central to the described incident.
