A
Explanation: A) The sticky secure MAC addresses feature enables a switch to learn the MAC addresses off a switchport and automatically enter them into the port security configuration.

The first x number of MAC addresses are learned (1 is the default), and then they are enabled as the only addresses that are allowed to send traffic over the switchport.
