An engineer must set up 200 new laptops on a network and wants to prevent the users from moving their laptops around to simplify administration. Which switch port MAC address security setting must…

`aging` is a setting for port security that defines how long a secure MAC address remains valid before it's removed; it doesn't prevent movement, but controls the lifespan of learned addresses.

`static` secure MAC addresses are manually configured for a port, which would be administratively burdensome for 200 new laptops and doesn't simplify administration.

The `sticky` MAC address security setting on a switch port learns the MAC address of the first device connected to that port and then automatically adds it to the running configuration as a static secure MAC address. If a different MAC address attempts to connect, the port goes into an error-disabled state, effectively preventing unauthorized device movement.

`maximum` is a setting that defines the maximum number of secure MAC addresses allowed on a port; it doesn't prevent movement, but rather limits the number of devices.
