1. When a switch receives a frame and the source MAC address is not found in the switching table, what action will be taken by the switch to process the incoming frame?
The switch will request that the sending node resend the frame.
The switch will issue an ARP request to confirm that the source exists.
*****The switch will map the source MAC address to the port on which it was received.
The switch ends an acknowledgement frame to the source MAC of this incoming frame.

2. Refer to the exhibit. How many collision domains are depicted in the network?
1
*****2
4
6
7
8

 

3. Refer to the exhibit. What action does SW1 take on a frame sent from PC_A to PC_C if the MAC address table of SW1 is empty?
SW1 drops the frame.
*****SW1 floods the frame on all ports on SW1, except port Fa0/1.
SW1 floods the frame on all ports on the switch, except Fa0/23 and Fa0/1.
SW1 uses the CDP protocol to synchronize the MAC tables on both switches and then forwards the frame to all ports on SW2.

 

4. If a network administrator enters these commands in global configuration mode on a switch, what will be the result?

Switch1(config-line)# line console 0

Switch1(config-line)# password cisco

Switch1(config-line)# login
*****to secure the console port with the password “cisco”
to deny access to the console port by specifying 0 lines are available
to gain access to line configuration mode by supplying the required password
to configure the privilege exec password that will be used for remote access

5. A network administrator uses the CLI to enter a command that requires several parameters. The switch responds with “% Incomplete command”. The administrator cannot remember the missing parameters. What can the administrator do to get the parameter information?
append ? to the last parameter
*****append a space and then ? to the last parameter
use Ctrl-P to show a parameter list
use the Tab key to show which options are available
