What is a direct method used for VLAN hopping?

The correct answer, which involves configuring a trunk port on the attacker's machine, highlights a technique where an attacker sets up their device to operate as a switch trunk. This method allows the malicious device to send traffic on multiple VLANs simultaneously.

In a network where VLANs are used for segmentation, if an attacker can convince a switch to treat their device as a trunk port, they can gain access to VLANs that should be isolated from each other. This occurs when the switch's configuration is not properly secured, allowing the attacker's non-compliant device to pass traffic from one VLAN to potentially unauthorized ones. This VLAN hopping threat exploits the way VLAN tagging works, taking advantage of improperly configured switches.

Other options, while related to security practices in a network, do not directly facilitate VLAN hopping. Disabling security features could potentially expose a network to various attacks but isn’t specifically a method for VLAN hopping. Stronger encryption might protect VLAN data from eavesdropping, but it does not help in accessing or crossing VLAN boundaries. Segmenting VLANs with firewalls is a sound security practice that aims to contain and control network traffic; it does not directly enable an attacker to hop from one VLAN to another effectively. Thus, configuring a trunk port on the
