200-301 - Network Fundamentals - Section 1.13
Describe switching concepts - MAC learning and aging, frame switching, frame flooding, and the MAC address table - and compare TCP to UDP.
Explain how a switch builds its MAC address table by learning source addresses, ages out stale entries, forwards known-unicast frames out a single port, and floods unknown-unicast, broadcast, and multicast frames out all ports in the VLAN. Compare connection-oriented TCP, with its three-way handshake, sequencing, and acknowledgements, against connectionless UDP, and choose the right transport for a given application.
