A network administrator needs to configure port security on a switch. Which two statements are true? (Choose two.)
A.
The network administrator can apply port security to dynamic access ports.
B.
The network administrator can apply port security to EtherChannels.
C.
When dynamic MAC address learning is enabled on an interface, the switch can learn new addresses, up to the maximum defined.
D.
The sticky learning feature allows the addition of dynamically learned addresses to the running configuration.
E.
The network administrator can configure static secure or sticky secure MAC addresses in the voice VLAN.
A. is incorrect because Dynamic access ports belong to vlans. THis answer implies that you can assign port security to vlan ports. Port security is assign to physical ports.
B. is incorrect because per port security guidelines and restrictions, you cannot enable port security on EtherChannels and a secure port cannot belong to an EtherChannel port-channel interface.
E. is incorrect because port security is applyed to an interface not to a logical grouping (vlan).
C. is correct. The key words are “can learn new addresses, up to the maximum defined.”
D. is correct as well
