Which type of MAC address is dynamically learned by a switch port and then added to the switch’s running configuration?

A.
Pervasive secure MAC address

B.
Static secure MAC address

C.
Sticky secure MAC address

D.
Dynamic secure MAC address

Explanation:
To mitigate MAC address spoofing attacks, a switch administrator can configure the
Cisco Catalyst switch to use sticky secure MAC addresses. When configured for sticky
secure MAC addresses, a Catalyst switch dynamically learns MAC addresses connected
to various ports. These dynamically learned MAC addresses are added to the switch’s
running configuration, thus preventing an attacker from spoofing a previously learned
address.
