Question:
Which switch characteristic helps keep traffic local and alleviates network congestion?

• high port density
• fast port speed
• large frame buffers
• fast internal switching

Explanation: Switches that have a lot of ports (high port density) reduce the number of switches required and keep some of the traffic locally on the switch, thus removing the need to send it between switches.
