Question

question 5
which network device makes forwarding decisions based on the destination mac address that is contained in the frame?
repeater
hub
router
switch

Explanation:

A switch builds a MAC - address table by learning the MAC addresses of devices connected to its ports. It then uses the destination MAC address in a frame to forward the frame to the appropriate port. A repeater simply regenerates a signal, a hub broadcasts data to all ports, and a router makes decisions based on IP addresses (layer - 3) rather than MAC addresses (layer - 2).

Answer:

D. Switch
