What is the dynamic table that stores information such as MAC addresses available on physical ports along with VLAN parameters associated with them?

• A. CAM table
• B. MAC address
• C. macof
• D. Port security

Answer: (A)

In a switch, the dynamic table that maps MAC addresses to the specific physical ports and the VLANs they’re reachable on is the CAM table (Content Addressable Memory). As frames pass through, the switch learns the source MAC address and the port it arrived on, recording the associated VLAN ID. This enables the switch to forward future frames destined for that MAC to the correct port without flooding. The entries are dynamic and age out when devices go silent, keeping the table current. The other options don’t fit: a single MAC address isn’t a table, macof is a MAC-flooding tool, and port security is a feature that controls which MACs are allowed on a port rather than describing the forwarding table itself.
