Refer to the exhibit. What is the effect of the configuration on interface FastEthernet0/2 for Switch SW1?
NO DIAGRAM: Answer is "It learns the MAC address of a connected device and stores it in the port security configuration."
It will allow a MAC address to be manually entered in the port security configuration.
It will disable the interface if more than one device is connected.
It learns the MAC address of a connected device and stores it in the port security configuration.
It learns the MAC address of other interfaces on the same Switch and will store it on the configuration.
MAC addresses will be dynamically shown in the MAC forward/filter table by default. To stop unauthorized hosts from accessing the LAN Switch and populating the MAC table, port security must be enabled on the interfaces. A very useful tool when configuring security in a LAN switch is to use sticky secure MAC addresses. The keyword _sticky makes the first MAC address connected into the port to record (stick) the address as static until a determined aging time is expired. For more information refer to: [Odom W. - Cisco CCENT - CCNA ICND1 100-101 Official Certification Guide, Chapter 8].
*** The choice "It will disable the interface if more than one device is connected." is technically correct as well since the commands say to only allow the learned MAC to pass traffic over this interface. Because of this, if the device is swapped for another or if a second device is connected via a hub or other such device then the interface will be disabled due to the violation type nor the max # of allowed MACs not being changed. Both or which are shutdown and 1 respectively***
