Which Learning Mode is set on the GE1 port for Port Security?

• A. Learn
• B. Disabled
• C. Classic Lock
• D. Auto

Answer: (C)

Port Security learning modes control how a port handles MAC address learning and access. Classic Lock locks the port to the first MAC address learned on that port, meaning no new MAC addresses will be learned and only that device can use the port until the lock is removed. This provides strong, single-host security for the GE1 port. Other modes either allow dynamic learning of multiple addresses (Learn), turn security off (Disabled), or operate in a mode that isn’t fixed to one MAC (Auto), which is why Classic Lock is the correct choice for a locked, single-device port.
