What will be the result if the following configuration commands are implemented on a Cisco
switch?
Switch(config-if)# switchport port-security
Switch(config-if)# switchport port-security mac-address sticky

A.
A dynamically learned MAC address is saved in the startup-configuration file.

B.
A dynamically learned MAC address is saved in the running-configuration file.

C.
A dynamically learned MAC address is saved in the VLAN database.

D.
Statically configured MAC addresses are saved in the startup-configuration file if frames
from that address are received.

E.
Statically configured MAC addresses are saved in the running-configuration file if frames
from that address are received.

Explanation:

In the interface configuration mode, the command switchport port-security mac-address
sticky enables sticky learning. When entering this command, the interface converts all the
dynamic secure MAC addresses to sticky secure MAC addresses.
