Which type of device uses the destination IP address to forward packets?

  1. Layer 3 router
  2. Layer 2 switch
  3. repeater
  4. hub

Answer(s): A

Explanation:

A Layer 3 router forwards packets based on the destination IP address. It operates at the network layer of the OSI model and uses routing tables to determine the best path for packet delivery. Unlike Layer 2 switches, which forward packets based on MAC addresses, routers handle logical addressing, making them crucial for inter-network communication.
