   A network administrator is configuring VLAN translation on a Dell SONiC switch. The goal is to translate VLAN 100 to VLAN 200 on interface Ethernet2. After applying the configuration, the administrator sends a frame with VLAN 100 into Ethernet2 and captures the frame on the egress interface. The capture shows VLAN 100. What is the most likely reason the translation is not working?

   • AThe translation rule was applied in the wrong direction.
   • BThe egress interface is in access mode.
   • CThe switch does not support VLAN translation on physical interfaces.
   • DThe frame was sent with an outer tag instead of an inner tag.

   A Dell SONiC switch has Q-in-Q configured on interface Ethernet1 with outer VLAN 100, and VLAN translation configured on interface Ethernet2 to map VLAN 200 to VLAN 300. A packet capture on Ethernet2 shows a frame with two tags: outer VLAN 100 and inner VLAN 200. What will the switch do with this frame?

   • AForward the frame unchanged because translation only applies to single-tagged frames.
   • BDrop the frame because Q-in-Q and VLAN translation cannot coexist.
   • CTranslate the outer VLAN 100 to 300, resulting in outer 300 and inner 200.
   • DTranslate the inner VLAN 200 to 300, resulting in outer 100 and inner 300.

   In which scenario is VLAN translation most commonly used?

   • AWhen a network needs to segment traffic into multiple broadcast domains.
   • BWhen a switch needs to provide redundancy for a failed link.
   • CWhen a network administrator wants to prioritize voice traffic over data traffic.
   • DWhen two networks that need to be interconnected use the same VLAN IDs for different purposes.

   While analyzing traffic on a link with VLAN translation configured, what should you observe in the packet capture?

   • AFrames with two VLAN tags.
   • BFrames with the original VLAN ID on both sides.
   • CFrames with the translated VLAN ID on the egress side.
   • DFrames with no VLAN tag.
