Which of the following parameters is not required if you want to communicate with a system on the same LAN?
  1. IP address
  2. Subnet mask
  3. MAC address
  4. Default gateway
Explanation
Answer: D - You need not configure the default gateway if you are configuring a system to communicate with a system on the same LAN.

Key Takeaway: The default gateway is the router that the host uses to send data to hosts on other networks. In this case, you do not need to set the default gateway as all of the data is staying on the same network.
