Disabling auto trunking and moving native VLANs to unused VLANs can help prevent VLAN hopping attacks as it separates the VLANs and prevents an attacker from accessing the native VLAN. Installing an additional switch or using MAC address filtering may not be effective in preventing VLAN hopping attacks. Installing a router to process untagged traffic on the VLAN may also not be effective as the router may not be able to prevent VLAN hopping attacks.
