Refer to the exhibit. Current PCs connected to SW1 and MAC address table are shown in the exhibit below. What two functions will SW1 perform, when it receives the Ethernet Frame shown below? (Choose two.)
SW1 will discard the frame.
The frame will be forwarded to all active ports.
The frame will be forwarded to ports Fa0/4 and Fa0/10.
The frame will be forwarded to all active port expect Fa0/10.
The MAC address FFFF.FFFF.FFFF will be recorded in the MAC address Table.
The MAC address 0000.00CC.3333 will be recorded in the MAC address Table.
An important function of a Switch is to learn MAC addresses and interfaces and map them into its address table. With a complete address table, a switch can make forwarding decisions based on the MAC addresses mapped to a specific interface. When a frame enters the switch and the source MAC address is not in the table, the switch makes a new entry. The table entry lists the interface from which the frame was received. In the case of the question, the Ethernet Frame is coming from Fa0/10 with a L2 Broadcast (FFFF.FFFF.FFFF) as destination MAC, which might be an ARP broadcast. The Switch will proceed to map the source MAC from the frame to its incoming interface. In order to find the owner of the destination MAC, the Switch will flood the frame to all ports except the one that it came from (Fa0/10).
