CISCO CCNA 200-301 Q96

What IOS command produced the following output?

A. show interface mac
B. show mac
C. show mac-address-table
D. show ip interface

Correct Answer: C

The output was produced by the show mac-address-table command. The show mac-address-table command displays a table of every learned MAC address and the switch port associated with the MAC address. The output shown in the question indicates that four MAC addresses have been learned by this switch, and the last column indicates the switch port over which each MAC address was learned, and for which frames destined for each MAC address will be forwarded. The MAC address table is built dynamically by examining the source MAC address of received frames.

The show ip interface command is a router command, and displays no information on MAC address tables.

The show interface mac and show mac commands are incorrect because they are not valid Cisco IOS commands.
