ADMIN, PLEASE FIX OR REMOVE THIS QUESTION: Refer to the exhibit. PC1 sends data frame to PC2. How does the switch handle the frame when it receives it on Fa0/1 interface? **NOTE FROM USER: THERE IS NO IMAGE/DIAGRAM**

It will add the source MAC and Fa0/1 interface to its MAC Address Table and forwards the frame outbound of Fa0/2

It will forward the frame outbound of Fa0/2 and do nothing more

It will send back a Destination Unreachable message to PC1

It will drop the frame because PC1's MAC address is not in the MAC Address Table

Explanation

The switch learns and builds it MAC Address Table by looking at incoming frame source mac address, it will add the source mac and the interface where it was received (In case of a Hub, the switch will map the mac addresses to a single source port). CCNA R&S Curricula: 2. The switch examines the source MAC address and compares it to MAC address table. • If the address is not in the MAC address table, it associates the source MAC address of PC 1 with the ingress port (Port 1) in the MAC address table (Figure 2). • If the MAC address table already has an entry for that source address, it resets the aging timer. An entry for a MAC address is typically kept for five minutes. 3. After the switch has recorded the source address information, the switch examines the destination MAC address. • If the destination address is not in the MAC table or if it’s a broadcast MAC address, as indicated by all Fs, the switch floods the frame to all ports, except the ingress port (Figure 3).
