Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In a switched network, switches learn MAC addresses and forward frames only out the port where the destination MAC address is located. When Computer A sends to Computer D, the switch looks up the MAC address of Computer D in its MAC address table and forwards the frame only to the port connected to Computer D. This is unlike hubs which broadcast to all ports or routers which operate at Layer 3.
