Where are MAC addresses and their virtual LAN parameters stored?

Where are MAC addresses and their virtual LAN parameters stored?

• A. In the firewall
• B. In the routing table
• C. In the CAM table
• D. In the DNS database

Answer: (C)

MAC addresses and their associated virtual LAN parameters are stored in the Content Addressable Memory (CAM) table of network switches. The CAM table is used to facilitate the rapid retrieval of MAC address information, which helps a switch determine where to forward incoming data frames. When a device sends a frame, the switch examines the source MAC address and adds it to its CAM table if it's not already present, along with the corresponding port to which the device is connected. This process enables efficient communication within local area networks (LANs), as the switch can send data directly to the appropriate port instead of broadcasting it to all ports. By maintaining the CAM table, the switch can optimize network performance and improve overall efficiency in data transmission.
