Network Hardware

Question 1

How do switches and bridges learn where devices are located on the network?

– When a frame enters a port, the source IP address is copied from the frame header
– When a frame enters a port, the destination Mac address is copied from the frame header
– When a frame enters a port, the source Mac address is copied from the frame header
– One a frame enters a port, the destination IP address is copied from the frame header

Answer 1

When a frame enters a port, the source Mac address is copied from the frame header
