Question 4

The figure shows the simplified topology of an enterprise campus network. On this network, the aging time of dynamic MAC address entries on switches is 300 seconds. The administrator connects PC1 to GE1/0/1 of SW1 and successfully pings the IP address of PC2 from PC1. Then, the administrator disconnects the Ethernet cable of PC1 from GE1/0/1 of SW1, immediately connects the cable to GE1/0/2 of SW1, and pings the IP address of PC2 from PC1. Which of the following operations does SW1 perform after receiving a data frame from PC1 when PC1 is connected to GE1/0/2 of SW1?

A. SW1 does not update the MAC address table until the original entry ages out. B. SW1 saves the mapping between the MAC address of PC1 and GE1/0/2 and deletes the mapping between the MAC address of PC1 and GE1/0/1. C. SW1 saves the mapping between the MAC address of PC1 and GE1/0/1, and also keeps the mapping between the MAC address of PC1 and GE1/0/2. D. SW1 deletes all MAC address entries and relearns them from all ports.
