In the given exhibit, interface ge-0/0/0 is configured to accept VLANs 101-120 and ge-0/0/1 is configured with flexible VLAN tagging, which means it can tag traffic with any VLAN ID specified. However, only VLAN 200 is explicitly mentioned for ge-0/0/1.
A: Traffic tagged with VLAN 101 will pass through ge-0/0/0 and will egress on ge-0/0/1 with the same VLAN tag, because the VLAN ID is within the allowed range on both interfaces.
B: VLAN 100 is not specified in the allowed VLAN range for ge-0/0/0 (which is 101-120), nor is it specified under ge-0/0/1. Therefore, it will be dropped.
