On Device B, the downlink port GigabitEthernet 1/0/2 permits secondary VLAN 2. The downlink
port GigabitEthernet 1/0/3 permits secondary VLAN 3. Secondary VLANs 2 and 3 are

associated with primary VLAN 5.

On Device B, the downlink port GigabitEthernet 1/0/6 permits secondary VLAN 6. The downlink
port GigabitEthernet 1/0/8 permits secondary VLAN 8. Secondary VLANs 6 and 8 are
