Explanation:
Port security is a feature supported on Cisco Catalyst switches that restricts a switch port to
a specific set or number of MAC addresses. Those addresses can be learned dynamically or
configured statically. The port will then provide access to frames from only those addresses.
If, however, the number of addresses is limited to four but no specific MAC addresses are
configured, the port will allow any four MAC addresses to be learned dynamically, and port
access will be limited to those four dynamically learned addresses. A port security feature
called “sticky learning, ” available on some switch platforms, combines the features of
dynamically learned and statically configured addresses. When this feature is configured on
an interface, the interface converts dynamically learned addresses to “sticky secure”
addresses. This adds them to the running configuration as if they were configured using the
switchport port-security mac-address command.

•Port security does not support EtherChannel port-channel interfaces.
Port security supports nonnegotiating trunks.
–Port security only supports trunks configured with these commands:
switchport
switchport trunk encapsulation
switchport mode trunk
switchport nonegotiate

Answer is F…, When Lab’d on a Cisco 3750X, this can be done on ports G1/0/1, G1/0/2, G1/0/3 and G1/0/24 ( Trunk )…. the Switchport Port-Security command was not an option on a Port-Channel or a Interface that was a Member of a Port-Channel…
