Comprehensive Explanation: The interface configuration shows that VLANs 2, 3, and 100 are tagged, meaning frames belonging to these VLANs are transmitted with VLAN tags. VLANs 4 and 6 are untagged, meaning frames for these VLANs are transmitted without tags. The command port hybrid tagged vlan 2 to 3 100 specifies that data frames for VLANs 2, 3, and 100 are transmitted with tags, while port hybrid untagged vlan 4 6 configures the interface to transmit untagged frames for VLANs 4 and 6.
