Which command will show the MAC addresses of stations connected to switch ports? A. show mac-address B. show arp C. show table D. show switchport Answer : A Explanation: One of the three main functions of a switch is to learn which devices—that is, MAC addresses—are associated with which interfaces or ports. This information is stored in a port address, or content addressable memory (CAM) table. You can view the CAM table by using the show mac-address-table command. The command show mac-address is short form of show mac-address-table . Topology In this simple topology there were four hosts connected to Sw-Host switch. Each of its IP address and MAC address are shown below the Host icons. The switch Sw-Hosts has been assigned IP address of 192.168.1.254. After some transactions of data between all hosts. Each and every MAC address of hosts will be stored in CAM table. Below is the output of show mac-address...

Refer to the exhibit. Switch-1 needs to send data to a host with a MAC address of 00b0.d056.efa4. What will Switch-1 do with this data? A.  Switch-1 will drop the data because it does not have an entry for that MAC address. B.  Switch-1 will forward the data to its default gateway. C.  Switch-1 will flood the data out all of its ports except the port from which the data originated. D.  Switch-1 will send an ARP request out all its ports except the port from which the data originated. Answer: C. Switch-1 will flood the data out all of its ports except the port from which the data originated. Explanation: When a switch received a frame it will check the destination mac-address of frame with its mac-address-table. If that particular mac-address found, then data will send to the interface where that mac-address associated. But if no interface is associated with that mac-address, then it will broadcast the...
