Answer: A

Explanation:

Port Security and Port Types You can configure port security only on Layer 2 interfaces. Details about port security and different types of interfaces or ports are as follows: Access ports–You can configure port security on interfaces that you have configured as Layer 2 access ports. On an access port, port security applies only to the access VLAN. Trunk ports–You can configure port security on interfaces that you have configured as Layer 2 trunk ports. VLAN maximums are not useful for access ports. The device allows VLAN maximums only for VLANs associated with the trunk port. SPAN ports–You can configure port security on SPAN source ports but not on SPAN destination ports. Ethernet Port Channels–Port security is not supported on Ethernet port channels.
