Which term stores information about the MAC addresses available on any given port of the switch?

• A. Port Security
• B. Switch
• C. CAM Table
• D. Sticky MAC

Answer: (C)

Switches keep a MAC address table that maps each learned MAC address to the port it was seen on. This storage, known as the CAM table, is what lets the switch forward frames efficiently: when a frame arrives, the switch looks up the destination MAC in the CAM table and sends it out only on the relevant port. If the destination isn’t in the table, the frame is flooded to all ports except the source.

Port Security is a feature that limits which MACs can be learned on a given port; it doesn’t hold the full MAC-to-port mappings for the whole switch. The device itself is a switch, not a term for storing MAC information. Sticky MAC is a method to populate CAM entries and persist them, but the actual storage of the MAC-to-port mappings is the CAM table.
