Which two statements are correct about VXLAN domains? (Choose two.)
A . With Layer 2 traffic, the VLAN ID is discarded before the packet is sent.
B . With Layer 3 traffic, the VLAN ID is discarded before the packet is sent.
C . With Layer 2 traffic, the VLAN ID is transmitted within the packet.
D . With Layer 3 traffic, the VLAN ID is transmitted within the packet.

Answer: AC

Explanation:

In VXLAN domains, when dealing with Layer 2 traffic, the original VLAN ID of the packet can be either transmitted within the VXLAN packet or discarded, depending on the specific implementation and configuration. When the VLAN ID is preserved, it allows for VLAN transparency, enabling the VXLAN to transport VLAN-tagged frames across the network. On the other hand, discarding the VLAN ID can simplify the encapsulation process but removes the original VLAN information from the packet.
