Which command is used on a Catalyst 2950 series switch to enable basic port security on the interface?

A.
set port-security

B.
switchport port-security

C.
set port-security enable

D.
switchport port-security enable

Explanation:
The switchport port-security command is an interface configuration command used on a Catalyst 2950 series switch to enable basic port security on the interface.
The syntax of the command is as follows:
switch(config-if)#switchport port-security
Switchport security can be used to:
– Limit the computers that are allowed to connect to the LAN (by specifying the MAC addresses allowed on the port)
– Limit the number of MAC address allowed to be accessing a port
– Set the action the port will take when a violation of the security rule occurs
The set port-security, set port-security enable, and switchport port-security enable commands are incorrect because these are not valid Cisco IOS commands.
Objective:
LAN Switching Fundamentals
Sub-Objective:
Configure, verify, and troubleshoot port security
