   A Dell SONiC switch connects two data centers. Data Center A uses VLAN 100 for its storage network, and Data Center B uses VLAN 200 for the same storage network. The storage arrays must be in the same broadcast domain for replication. The administrator configures VLAN translation on the inter-switch link. Which additional consideration is critical for this design?

   • AQ-in-Q must be enabled on the inter-switch link.
   • BThe inter-switch link must be an access port.
   • CThe storage arrays must be configured with both VLAN IDs.
   • DThe translation rule must be configured in both directions.

   A Dell SONiC switch is configured with 'switchport vlan mapping 100 200'. What happens to frames received on this interface with VLAN tag 100?

   • AThe frames are forwarded unchanged with VLAN 100.
   • BThe frames are dropped because VLAN 100 is not allowed.
   • CThe VLAN tag is changed to 200 before forwarding.
   • DThe frames are forwarded with both VLAN tags 100 and 200.

   A network engineer is troubleshooting a VLAN translation issue on a Dell SONiC switch. The translation rule maps VLAN 10 to VLAN 20 on interface Ethernet1. Frames entering Ethernet1 with VLAN 10 are correctly translated to VLAN 20. However, frames returning from the other side with VLAN 20 are not translated back to VLAN 10. What is the most likely cause?

   • AThe return frames are untagged and bypass translation.
   • BThe reverse translation rule was not configured.
   • CThe return frames are double-tagged and cannot be translated.
   • DThe switch only translates frames on egress, not ingress.

   A packet capture on a Q-in-Q tunnel interface shows frames with two VLAN tags. What does the outer tag represent?

   • AThe service provider's VLAN that identifies the tunnel or customer.
   • BThe customer's original VLAN ID.
   • CThe destination MAC address of the frame.
   • DThe priority bits for quality of service.

   A Dell SONiC switch connects a customer network that uses VLAN 100 to a service provider network that uses VLAN 500. The customer's traffic must be forwarded to the provider with the VLAN ID changed from 100 to 500. Which configuration should the administrator apply on the switch interface facing the provider?

   • AA Q-in-Q rule with outer VLAN 500 and inner VLAN 100.
   • BA VLAN translation rule that maps VLAN 100 to VLAN 500.
   • CA trunk port with both VLAN 100 and VLAN 500 in the allowed list.
   • DAn access port assigned to VLAN 500.
