Referring to the following figure, what will happen when a frame destined for 0001.6c58.486f enters the switch?
Answer Options
The frame will be forwarded to the uplink port.
The frame will be forwarded to all active ports except the one on which it was received.
The frame will be dropped.
The frame will be forwarded to a MAC address of ffff.ffff.ffff.
Correct Answer: B
Explanation
When a MAC address is unknown by the switch, the switch will forward the frame to all ports; this is also called flooding the frame. When the destination system acts upon it, the switch learns its MAC address through source MAC address learning. The uplink port will receive a copy of the flooded frame, but it will receive this copy along with all other active ports. Switches never drop frames unless the CRC for the frame is incorrect. The frame will never be forwarded to a broadcast MAC address of ffff.ffff.ffff unless that is the intended destination.
