Question

A switch differs from a hub because, it ________.
 

• A. operates at Layer 1
• B. broadcasts all frames
• C. uses MAC tables for forwarding
• D. only supports half-duplex

Hint:

Switches are more efficient than hubs because they minimize traffic on the network by only sending data to the intended destination.

Answer 1

The Correct Option is C

A switch differs from a hub in that it operates at the Data Link layer (Layer 2) and uses MAC address tables to forward data only to the correct destination port, unlike hubs that broadcast frames to all ports.
