The configuration of an interface on a switch is shown below.

Huawei hybrid interfaces support tagged and untagged frame forwarding, allowing administrators to control how frames associated with different VLANs leave a switch.

The command port hybrid untagged vlan 10 specifies that frames belonging to VLAN 10 are transmitted without an 802.1Q VLAN tag.

The command port hybrid tagged vlan 20 specifies that frames belonging to VLAN 20 retain their VLAN identification during transmission.

Therefore, when a frame associated with VLAN 20 leaves this interface, the switch forwards it with its VLAN 20 tag intact.

The command port hybrid pvid vlan 10 determines the default VLAN classification for untagged frames received on the interface. It does not require outgoing VLAN 20 frames to be converted into VLAN 10 frames.

Consequently, option D correctly describes the interface ' s egress behavior.
