   Two enterprise networks are being merged. The first network uses VLAN 10 for its finance department, and the second network uses VLAN 20 for the same department. The networks are connected through a Dell SONiC switch. The finance VLANs must communicate as a single broadcast domain. Which feature should be configured on the connecting switch?

   • AQ-in-Q tunneling with outer VLAN 10.
   • BVLAN translation to map VLAN 20 to VLAN 10 on the connecting interface.
   • CA trunk port carrying both VLAN 10 and VLAN 20.
   • DA routed sub-interface for each VLAN with IP forwarding.

   An administrator has configured VLAN translation on a Dell SONiC switch to map VLAN 10 to VLAN 20 on interface Ethernet1. To verify the configuration, the administrator sends a test frame with VLAN 10 from a host connected to Ethernet1. What should the administrator observe in a packet capture on the other side of the switch?

   • AThe frame still has VLAN 10 because translation only applies to the outer tag.
   • BThe frame has two tags: VLAN 10 and VLAN 20.
   • CThe frame is untagged because translation strips the VLAN tag.
   • DThe frame has VLAN 20, confirming the translation rule is active.

   What is the primary function of VLAN translation?

   • ATo encrypt VLAN traffic between switches.
   • BTo add an outer VLAN tag to frames for tunneling.
   • CTo combine multiple VLANs into a single broadcast domain.
   • DTo map a VLAN ID in one domain to a different VLAN ID in another domain.

   After configuring Q-in-Q on a Dell SONiC switch, a technician wants to confirm that frames from a customer are being double-tagged correctly. The technician captures traffic on the core-facing trunk port. Which frame characteristic confirms the Q-in-Q tunnel is operating as expected?

   • AThe frame has a single VLAN tag with the customer's VLAN ID.
   • BThe frame has an outer tag equal to the customer's VLAN ID and no inner tag.
   • CThe frame has two VLAN tags: an outer tag with the provider VLAN and an inner tag with the customer VLAN.
   • DThe frame has no VLAN tag because the customer traffic is untagged.

   A Dell SONiC switch is configured for Q-in-Q on interface Ethernet1 with outer VLAN 200. A packet capture on the core-facing port shows frames with an outer tag of 200 and an inner tag of 300. However, the customer reports that traffic from VLAN 300 is not reaching the remote site. What is the most likely cause?

   • AThe customer's inner VLAN 300 is not configured on the switch.
   • BThe core-facing trunk port does not have VLAN 200 in its allowed list.
   • CThe outer VLAN tag should be 300, not 200.
   • DThe interface is in access mode instead of trunk mode.
