Switches:
A)learn addresses by reading the source and destination addresses
B)operate at the physical layer only
C)connect two ore more network segments that use different data link protocols
D)connect two or more network segments that use different network protocols
E)have become more popular than layer 2 switches

Question

Quizplus · Accepted Answer

Switches learn addresses by reading the source and destination addresses in the data packets they receive, allowing them to build a table of which devices are connected to which ports. This enables them to forward traffic only to the relevant port, improving efficiency and reducing network congestion. Choices B, C, D, and E are incorrect because switches operate at the data link layer (not the physical layer), connect network segments that use the same data link protocol (not different protocols), and are more popular than layer 3 switches (not layer 2 switches).
