  1. option D is correct. Simple way to understand. devices are untaged to vlan 2 and 3 on both the switch and the uplink is tagged to vlan 2 and 3 which allows it to carry the traffic from vlan 2 and 3 between the switches .

  2. i am not shure. Device 1 and 4 vlan2, device 2 and 3 vlan 3. Tag vlan 2,3 for both swithes.
    Answer D or?
