The network shown in the exhibit below was recently deployed. Switch SW1 has an existing populated MAC Table, however SW2 has no entries in its MAC Address table. All SW2 ports are in VLAN 20. SW1 and SW2 trunk on their gigabit interfaces. A frame is generated in PC1 with destination MAC address of PC4. How does the flooding process occur for both Switches? (Choose two)
SW2 will ignore the frame because there are no entries in its MAC Table
SW1 will forward the frame to all ports except Fa0/1
SW2 will forward the frame to Fa0/1
SW2 will forward to all ports except Gi0/1
SW1 will forward the frame to Gi0/1
SW1 will ignore the frame because there are no entries in its MAC Table
The two main functions of a switch is to flood or forward frames and to learn or populate its MAC address table with MAC addresses and out-going interfaces. When a frame enters the switch and the destination MAC addresses is unknown in the switch's MAC address table, the Switch will flood or forward copies of the frame out all ports, except the port on which the frame was received. On the other end the unknown device receives the frame and sends a reply. The switch will build a correct MAC table entry for the unknown device based on its source MAC address.
