Question #1
Which of the following best describes how a switch functions?
A.   It connects multiple cable segments (or devices) and forwards frames to the appropriate segment.
B.   It connects multiple cable segments (or devices) and broadcasts frames to all of its ports.
C.   It connects multiple segments of different architectures. It translates frames and broadcasts them to all of its ports.
D.   It connects multiple segments of different architectures. It translates frames and forwards them to the appropriate segment.
Question #2
How do switches and bridges learn where devices are located on a network?
A.   When a frame enters a port, the source MAC address is copied from the frame header.
B.   When a frame enters a port, the source IP address is copied from the frame header.
C.   When a frame enters a port, the destination IP address is copied from the frame header.
D.   When a frame enters a port, the destination MAC address is copied from frame header.
