Disabling auto trunking and moving native VLANs to unused VLANs is the best choice to prevent VLAN hopping attacks. This prevents an attacker from accessing the native VLAN and hopping to other VLANs. Installing an additional switch to isolate traffic or using MAC address filtering are not effective measures to prevent VLAN hopping attacks. Installing a router to process untagged traffic on the VLAN is also not a recommended solution as it can potentially introduce more security vulnerabilities.
