Refer to the exhibit. The entire contents or the MAC address table are shown. Sales-4 sends a data frame to Sales-1. What does the switch do as it receives the frame from Sales-4?

Question

Accepted Answer

B. Insert the source MAC address and port into the forwarding table and forward the frame to Sales- 1. When Sales-4 sends a frame, the switch first learns Sales-4's MAC address and the port it came in on (Gi1/4) and adds this entry to its MAC address table. Since Sales-1's MAC address (destination) is already in the table associated with Gi1/1, the switch will then directly forward the frame out of port Gi1/1 to Sales-1.

Answer

A. Perform a lookup in the MAC address table and discard the frame due to a missing entry. The switch will perform a lookup, but it will not discard the frame because Sales-1's MAC address entry is present in the MAC address table.

Answer

C. Map the Layer 2 MAC address to the Layer 3 IP address and forward the frame. Mapping Layer 2 MAC to Layer 3 IP addresses is typically an ARP function, not the primary action of a switch forwarding a known unicast frame.

Answer

D. Flood the fr me out of all ports except on the port where Sales-1 is connected. The switch only floods a frame if the destination MAC address is unknown or it's a broadcast/multicast; here, Sales-1's MAC is known in the table.
