A junior network administrator was given the task of configuring port security on Switch A to allow only PC_A to access the switched network through port fa0/1. If any other device is detected, the port is to drop frames from this device. The administrator configured the interface and tested it with successful pings from PC_A to RouterA, and then observes the output from these two show commands.

Port security needs to be enabled on the interface.
Port security needs to be configured to allow only one learned MAC address.

As we see in the output, the Port Security is in Disabled state (line 2 in the output). To enable Port security feature, we must enable it on that interface first with the command: SwitchA(config-if)#switchport port-security -> B is correct. Also from the output, we learn that the switch is allowing 2 devices to connect to it (switchport port-security maximum 2) but the question requires allowing only PC_A to access the network so we need to reduce the maximum number to 1 -> D is correct.
