Refer to the exhibit. A junior network administrator was given the task of configuring port security on
SwitchA 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.
Which two of these changes are necessary for SwitchA to meet the requirements? (Choose two.)
