    Hi, 

    Please help me to understand this question:

    Config below:

    -----------------
    [edit interfaces ge-1/0/0]
    user@host#  show
    vlan-tagging;
    native-vlan-id 55;
    unit 0 {
        family bridge.  {
                interface-mode trunk;
                vlan-id-list   [55    56]
           }|
    }


    Answer choices:

    1) The ge-1/0/0 interface will transmit any outgoing frames associated with VLAN 56 as untagged frames
    2) The ge-1/0/0 interface will associate any untagged frames that are received with VLAN 56
    3) The ge-1/0/0 interface will transmit any outgoing frames associated with VLAN 55 as untagged frames
    4) The ge-1/0/0 interface will associate any untagged frames that are received with VLAN 55

    Why choices 1 and 2 are the correct answers, and not 3 and 4? I thought since VLAN 55 is configured as native VLANS, and native VLANs are
    untagged, thus, the answers should be 3 and 4.

    Thanks,
