Selected Answer: D
The correct behavior for an EX Series switch when it receives a frame with a known destination MAC address is to forward the frame out the specific port associated with that MAC address. This is described in option D. Option A describes the behavior for a frame with an unknown destination MAC address, where the switch would flood the frame out all ports in the VLAN except the ingress port.

It should be D as the Frame is apparently not BUM traffic but simple Unicast. So it will be sent to the destination port in the same Ingress VLAN. It will not be flooded, as A suggests.
