What addressing information is recorded by a switch to build its MAC address table?

  • the destination Layer 3 address of incoming packets
  • the destination Layer 2 address of outgoing frames
  • the source Layer 3 address of outgoing packets
  • the source Layer 2 address of incoming frames
    Answers Explanation & Hints:

    A switch builds a MAC address table by inspecting incoming Layer 2 frames and recording the source MAC address found in the frame header. The discovered and recorded MAC address is then associated with the port used to receive the frame.
