Explain how a managed switch learns and forwards frames using the MAC address table, including unicast, broadcast, unknown unicast, and multicast behaviour within a VLAN.
Apply VLAN concepts to segment a network, including default VLANs, data VLANs, voice VLANs, management VLANs, and the operational purpose of separating broadcast domains.

Implement inter-VLAN routing by selecting the appropriate method, including switched virtual interfaces (SVIs) on a multilayer switch and router-on-a-stick using subinterfaces.

Interpret switch interface status and common implementation outputs to confirm VLAN membership, trunk operation, duplex and speed settings, and administrative state.

Evaluate when to use features such as port security and MAC filtering at the switchport as part of a basic implementation scenario without confusing them with broader security-policy troubleshooting tasks.
