An attack where an attempt is made to access traffic on a restricted VLAN is called what?

• A. Virtual Local Area Network (VLAN)
• B. VLAN Hopping
• C. Virtual Private Network (VPN)
• D. Virus

Answer: (B)

VLAN hopping centers on breaking out of the intended network segmentation. VLANs separate traffic into different broadcast domains, so devices in one VLAN should not see traffic in another. An attacker attempts to bypass that boundary by having switches forward frames onto a different VLAN, effectively moving (hopping) into restricted traffic. This is a direct way to access networks that should be isolated, which is why this option is the best description of the attack described in the question. The other concepts are not attacks that target VLAN isolation: a VLAN is just the segmentation itself, a VPN is about securely tunneling remote connections, and a virus is malware, not a technique to bypass VLAN boundaries.
