Which two statements are true about how switches handle Layer 2 traffic? (Choose two.)

The correct answer is B. The MAC address is learned based on the source MAC address. D. Traffic is forwarded based on the destination MAC address. In Layer 2 switching, switches learn MAC addresses based on the source MAC address of incoming frames and forward frames based on the destination MAC address. When a switch receives a frame, it records the source MAC address and the port on which it arrived. This allows the…

Explanation

In Layer 2 switching, switches learn MAC addresses based on the source MAC address of incoming frames and forward frames based on the destination MAC address. When a switch receives a frame, it records the source MAC address and the port on which it arrived. This allows the switch to know where to send traffic destined for that MAC address. Forwarding Based on Destination: The switch then looks at the destination MAC address and forwards the frame out of the port associated with that MAC address. If the MAC is unknown, the switch floods the frame to all
